Van’s Aircraft to Build SLSA RV-12iS and RV-12iST at Oregon Headquarters


August 31, 2018.  0001Z   Issue #4,644.   
  Wishing you and yours a happy, safe and RV-filled weekend!

Updated Groundtrack of RV-9A Around the World ...1045Z.  Landed!!!


RV-12iS KAI update

lots of updates out for the 12iS

Section 1, 2, 3, 5 and 28 (rudder pedals mislabeled & F-1289C-L tubing length change)

Interesting things in Section 1:
•There is a "Section 35GiS/U Premium Brake System" optional kit.
•The "Section 41B: Canopy Glare Shield" is in grey (not available yet), but I'm sure I have the glare shield in my finishing kit (?)
•New "Section 42PiS: GTN650" - so that's an option for E-LSA too i guess. gosh i wish IFR navigators didn't cost an arm and a leg.

Mistake drilling Flap Tube Horns

Installing flap tube in section 40 of fuse build. After drilling horns, rechecked the angle using the Flap Horn Jig. Well, evidently, something shifted while drilling. #&*@#%*

I'm 3/32" off in my angle on one side only. (see gap in pic)


Sad RV Story ...Mel Asberry

January 10, 1989, after a long conversation with Richard Vangrunsven, Ann, Myself, and Red Marron ordered 2 RV-6 kits. In May of 1993 both airplanes flew within 2 days of each other. Late into Phase I, I watched Bob Newton take off in N168TX for it's aerobatic wring-out. That's the last time I saw that airplane fly without me in it....until yesterday.

Yesterday the airplane took off for its new home in Louisiana. After a thorough interview, a very nice couple adopted N168TX. I am convinced that they will care for her just as they do their Cessna L-19, but we're sure gonna miss that bird.

The Carvair....pictures, and a new thread.

104*F heat index Wednesday in N. Texas, so any flying needs to be done early early.  I woke up 0500 Wednesday and couldn’t go back to sleep, so I drove through the drive thru at Whataburger for a breakfast burrito and Jeeped out to the airport for an RV gas run up to KGLE.

Randy told me awhile back that he parked under the Carvair (wikipedia) on the ramp there in the shade once, so I threw my compact chair and the laptop in the baggage area and launched. 13 minute flight up, breakfast in a bag, a VERY nice workspace view while digging through the morning admin tasks and email.  Some gas and RTB for some treadmill time before heading home to work more.  Yes, I did call the airport manager the day before and made sure it was OK.  Nice guy.  It's parked way out away from everything - nice and quiet.

I might be on to something using the RV to find ‘unique office space’ once a week or so.  The deal breaker is shade this time of year.  No shade no dice.   Developing….

In the mean time, I’ve started a thread where you can post pics of non-standard places you've viewed VAF. If you have an interesting VAF viewing pic feel free to join in.   Rob Reece and I laughed at the title we thought up for the thread (Where U Been VAF’n?).   ‘Keep Calm and VAF On’ was a finalist.  ;^)

View all the pics.


The Bluegrass State  ...petehowell

It was summer RV vacation time and our best laid plans for Glacier went up in smoke for for the 2nd year in a row, so we did a last minute audible, heading south to Kentucky, for history, booze, caves, camping, and hiking.......

I took my last 2 calls of the day at the hangar while Andi packed the plane - we then launched and headed to 3TR - Niles, MI to have dinner and overnight with Mom.   ...


Updated panel mockup ...jjbardell

Updated my blog based on all the great feedback thus far. Looking forward to continuing to refine and have now engaged UpNorthAviation to help finalize the layout. Love to hear feedback on the panel. I also am installing my gear switch just to the left of the throttle. I think it’ll be best there.

Here’s a recent photo arriving into Oshkosh.


Thoughts on ditching after a big accident with my RV7 in 2015 ...luigi_from_italy

You may recall a big accident happened in Italy on 31st May 2015 during an Airshow along the Adriatic sea. My close friend and formation flying pal, Marco Ricci, died in the accident, I could ditch my RV7, I-AMEL, in the sea and come out with a minor brush on my left hand.
There’s a great analysis that AOPA USA have made on it, just to help to recall and there are some interesting thoughts that I would like to share with you on the ditching itself. Here's AOPA Live:

AOPA Live 4 June 2015

Few words on the accident itself which was deeply analyzed by our national NTSB (ANSV): we flew this routine so many times during our formation training with the help of formers Frecce Tricolori pilots (Frecce Tricolori are the Italian Blue Angels), including the day before for the saturday “test” of the Airshow. Therefore it was absolutely a surprise (for me) the abrupt “recovery” from the inverted flight of my pal (while I was flying under it), Marco Ricci. That was not the plan, no radio call for distress and no usual recovery from inverted flight without loss of altitude.
Everything has been X-rayed from the italian NTSB: “luckily” (in order to understand the probable cause of the incident), that day we had many GoPro mounted, including one in the cockpit of Marco, directly facing the pilot. The GoPro was initially lost in the sea, but found by someone and sent anonimously to the Italian Coast Guard 2 days after the accident. From this video and the post mortem, the probable cause has been found on the incapacitation of the pilot for a “stroke” (not exactly a stroke, I am not a cardiologist).
You can download (unfortunately in Italian) the full PDF report on www.ansv.it., maybe using Google Translate.

Why am I writing only now?

Well, first of all, I restarted flying with my own plane (actually an Extra 330 LT). I continued flying almost immediately; a friend of mine, just 1 month after the accident, lent me his RV10 for a tour in Italy and I continued flying as a flight instructor on Tecnams, but it’s not like having your plane.

Another reason is how valuable is this forum and, as you will read later, there are lessons that I have red on this forum which came handy (and actually remembered!) during my ditching (believe it or not). I am sure that I can give some suggestions in the unlikely (as the PA on airliners say) of ditching with an RV.

Quick note, I have a full video (which is not pubblic) of my ditching (one GoPro was mounted facing forward on the back of my RV7), so what I am writing here, is clearly visible, so no “allucinations” after an accident.
Anyway you can see a lot of videos on YouTube (there were TV and more than 50K people on the beach), just search for “Incidente Alba Adriatica” (Incident in Alba Adriatica, which is the city along the coast where the Airshow took place).

My experience on RV7 is consistent, I made my FAA License in 1994 then European one in 1995 and I logged more than 1.000 hrs as a PIC on my RV7 (sliding canopy, O-360-A1A and Sensenich then Hartzel Scimitar Prop), flying X-countries (also from Italy to Morocco, which is not a short hop), pylon races with the 3R British Association and a lot of short grass fields in Italy, usually 1.500 ft, no IFR. One things that should be mentioned is that just 2 years before my ditching, I have made a water egress training test with a professional guy in a pool (although I am a good swimmer, I am 1.90 mt tall and thinking of ditching in the relatively small cockpit of the RV has been always something that I thought possible due to long X-country in open waters).

The whole thing from the mid air collision lasted a little bit more than 2 minutes (2 minutes and 20 seconds), but lot of things happened and many things were thought, analyzed and made.

In the whole process of ditching, things were really calm (until a certain point that I will explain) and that’s not because I have steel nerves, but just for one simple and understandable reason.

A catastrophic mid air collision is something that you can hardly tell and that’s what I thought during the big collision: I clearly remember (you can see from the video) a lot of noise, litterally falling from the sky with a lot of negaive g's, a big shade in the cockpit, my canopy obscured by the wing of the other aircraft and the nose down 30 degree (starting at just 500 feet AGL) with the sea approaching. I thought: OK, now it’s going to finish. This is so vivid.

For pure luck, although left wing was really damaged, prop bent, engine out, left flap bent and after a difficult recovery at just 40 feet from the sea, I found the aircraft controllable (almost) with light again “ON” in my cockpit.

It was so surprised (after being 100% that I was going to die) that I thought: “OK, I have to ditch, but the worst has passed, prepare yourself”.

Part 1


Status Update ...David Paule RV-3B

Here’s a photo of the rivet holes in the side skin that are hidden by the wing. The row at the top of the photo doesn’t need to be flush. The plans are a bit vague about this area - I’m sure that other people have built their planes a little differently here. But for me the ease of riveting is more important than the extra work dimpling them. I could have gotten the AN442 flat protruding head rivets for this but I didn’t. Those are as easy to set as flush ones and are otherwise like universal-head rivets, but with a flat top. While we’re thinking of easy-to-set rivets, if you go back to reread that riveting spec MIL-R-47196 that’s on Van’s site, I’m pretty sure it says that flush rivet sets can be used on universal-head rivets. That’s also easy. But there’s a small dimensional window between a proper shop head and going too far squishing the factory head, so I haven’t been doing that.

The area outlined by the red dashed line will not be glued.  ...


Plug PIREP on Long XC ...pstraub RV-12

If you are wondering about the spark plugs, here is a before and after pic of cylinder 1, lower plug. This is pretty much indicative of all 8 plugs. The before is after 70 hours of premium unleaded auto fuel (Chevron Supreme) and the 'after' is after the last 40 hours burning 100LL. Yikes!!

Blueberry Run  ...Vlad RV-9A

John Fleurent told me about the place a year ago. Deblois, Maine 43B has a great paved airstrip right in the middle of blueberry fields. The picking season is over but there are still a lot of ripe berries left. Day off, I go.  ...


Milestone: Kit Arrives ...Brantel RV-10

So my emp/tailcone arrived yesterday. So I am 0 and 4 for no crate damage from ABF. I said I would never use them again back in the RV-7 build days but Barb at Van's told me that they are actually fairly low on the damage rates. My experience has been different but oh well...


Seaside Municipal (56S) Fly-in BBQ, Sept. 15  ...Randall Henderson RV-6

The Seaside Oregon Municipal Airport Fly-in BBQ is set for September 15, 2018.

We fire up the grill around 11, but fly in any time. This is in conjunction with the EAA Chapter 105 Fly-out to Seaside. I'm hoping for a good turnout from RV-ers and others!

We have some bikes we can loan to people who want to go into town, and the taxi ride is super cheap, so if you want to make a day of it, all the better.

A few things to keep in mind: FLY FRIENDLY -- no buzz jobs, use the standard pattern, no early turnouts, and don't linger unnecessarily over neigborhoods, especially Gearhart (NW of the airport). And use caution for tethered paraglider activity over the beach 3 miles NW of the airport, up to 3000'.

It'll be helpful to have an idea who / how many might be coming so PM me if you think we might see you.


Oshkosh 2018 - BullockAir-A-Palooze ...bullojm1 RV-7

I've been planning this Oshkosh/Airventures trip (coined BullockAir-A-Palooza) for some time now - I've been wanting to shuffle things up from years past as I've had friends move to new locations in the US -- As you have followed along in the past, I use this week off work to do the Oshkosh thing, and then visit a bunch of college friends around the US. This year I had a friend move out to Fort Collins, CO, so I decided to take the RV further west than she's ever been before.

My original itinerary was Cleveland - Oshkosh - Ft Collins - Des Moines - Detroit - Buffalo - Home. Weather was a MAJOR challenge along the route. Low ceilings, rain, headwinds, turbulence, etc.. It was the most challenging trip I've ever taken in the RV.  ...


RV-4 engine mount question  ...AX-O

Looking for real data from someone that has converted an RV-4 long gear from conical mount to a Dynafocal mount.

Specifically, did the prop flange end up in the same place? meaning no cowl mods were done. The vertical and lateral offsets were the same.

In the process of this prop swap I am evaluating the possibility to swap out engine mounts. Thanks for any help you can provide.

Biggest RV Smile Ever ...Rob Traynham

I had the great honor today of taking Sean Rupert on his first ever lightplane ride. Sean is a recent graduate of the Greenville Tech Aviation Maintenance program where I am also a student (at 67 years old!).  He is a really great guy and I had been promising him a ride for some time. I knew this morning, when the day broke cool and clear, that this was THE morning. Sean flew it almost the entire time and I couldn’t help but notice that famous RV grin!


Life Update ...trishrussell (SchoolMom)

We definitely live on the best airpark in the south, possibly in the country. For those of you who know me (probably as SchoolMom), you know I have some major challenges. We are coming up on the third anniversary of my almost leaving this Earth, not by RV. My brain blew a gasket just after ordering salmon for dinner at a local restaurant. Medically, I had an AVM (arteriovenous malformation) rupture. No one knew I was born with a tangle of veins and arteries in my brain.When it ruptured it caused a massive stroke. I spent two months in the hospital and am still working on recovering. I'm back to flying, with the help of neighbors. Ron Schreck wrote about my recovery early on. He was the first to get me back in the air and follow me through when I couldn't resist the need to roll my RV. Currently, Mike Stewart flies with me at least weekly. I have almost no feeling on my left side. My left arm and hand are basically useless. But, with a safety pilot, I fly. Imagine pushing on the rudder without being able to feel it. Getting in and out of the plane is probably the biggest challenge, but it is getting easier.

Which brings me back to the topic, as RVers we are familiar with the friends being involved with RVs brings. Now, imagine a community of aviators who are truly friends. Gold Hill Airpark is such a place. We had only lived here a few months when my rupture happened. The house we were building had just finished being framed. I knew more neighbors than Mark because I was the pilot in the family. This community came together to make sure we had what we needed. For the two months Mark came home from the hospital to a hot meal. When I needed large shirts to dress easily they were at our door. And of course, when it was time to get me in the air, that happened. This community gathers as friends daily. Neighbors fly together, help each other with projects, or just gather on a porch for an evening beverage. We have parties on a regular basis, whether it's an impromptu birthday party, a Memorial or Labor Day potluck, a neighborhood BBQ & bluegrass party, or our December progressive dinner, there is always something.

The summer before my rupture I obtained my NC real estate broker's license. The plan was to supplement a teaching salary and retire in style with a part-time job when I reached 65. I am active in real estate. It is something I can do again with my limitations. My favorite listings are at our airpark helping others realize how wonderful airpark living can be. If you have ever thought of living on an airpark you must come visit NC25. Currently, there are two houses and three vacant lots for sale. The houses are a 5850 sft three story home asking $550,000 and a single story 1841 sft home asking $312,000. The lots range in price from $59,000 to $75,000. Our airpark is almost full. And, as I said, we are the best airpark! Check us out on airnav or fly in for a visit. Our house has a windsock in the front yard. You can't miss us. We have plenty of room in the hangar for a visiting bird. I'm the girl who insisted on a hangar with a 50' door.

Here is a picture of the really nice house being offered for $312,000. I would love to sell it to a RV owner or builder.

New RV9 Owner Chimes In ...ALagonia

I am now the new owner of the airplane that is affectionately known as The Clown Plane. It is an RV9 built by Stein for his brother and dad. The inspiration for the paint scheme was a Fisher Price childs plastic hammer. And if you can visualize that hammer you will understand why it is called The Clown Plane.

It was finally delivered to me late this past Wednesday. Since Thursday I have put 6.3 hours on her. I have over 4,500 hours TT flying some very cool airplanes but have been humbled by that little rubber wheel in the back. I look forward to becoming good friends with that little rubber wheel.

All kidding aside I just want to say a big thank you to Stein for what he did for me and for putting up with me and my one million questions while we went through the purchase. Thank you for everything Stein. You did what you said you would do and more. And I appreciate that.

Also a big thanks to his brother Zweit who made sure I knew what I was buying. Never over promising and always speaking clearly and honestly. How refreshing in this world.

And yes, I have that Vans grin. Finally.


VAF Site Sighting.

Taken Monday 0715 at the Denton Creek Regional Spaceport and Tire Care Center (3 n.m. from my home field - my little hideaway like in the movie Oblivion).  Nobody but me and my laptop for a couple miles - a place to pick out stories for the VAF front page and do site maintenance in the shade and in the quiet.  A place to start the daily assault on Mt. Email.

RV related?  Yep, that's the forums there on my laptop <g>.  I've written in the RV-15 thread I'll drop this thing like third period French to fund an RV Super Cub if it comes to market.  Give me s/n 1 and brace for thousands of pictures. ;^).  I'll even organize the first RV Super Cub backcountry fly-in and star party.  I'll pick a dark spot and bring the telescope.

RV-7 Milestone ...Byorn (Katy, TX)

Fuselage riveting done.  For me, finishing the fuselage skins was more satisfying than flipping the canoe. After removing the vinyl and cleaning with MEK, I just sat there for a minute ogling the shiny aluminum.

Couldn't have done it without my trusted rivet shooter Carol.


Paint before FAA inspection? ...Tom Herrmann's first post

Does the FAA allow complete painting of a homebuilt before the airworthiness inspection? Obviously, painting the wings, control surfaces, fairings, etc. would be much easier before final assembly. Any advantages of waiting until after the inspection before painting that I might be missing?

Old Belts and Harnesses ...David Paule

I've got a Cessna in addition to the RV-3B that I'm building. I contacted the company that made my aftermarket belts and shoulder harnesses and got a prompt reply. Not bad for something I'd bought 30 years before. Here's part of what he said:

"The next thing is that these assemblies life expectancy are somewhere between 10 and fifteen years depending on a lot of factors(environmental exposure, hours of use, etc...) Replacement now is based on what is known in Part 21 as Continued Airworthiness. If the product meets the requirements of the Instructions for Continued Airworthiness they are operational. Yours are 30 years old. They are way past replacement time and actually were built before harnesses were TSO'd, meaning the part number you have cannot even be built by AmSafe. When your harnesses were purchased, if they are our harnesses, the mandatory replacement was every 10 years. This was before the TSO regulation and ability to inspect to Continued Airworthiness was in place."

Now for our experimentals, we probably don't need to worry about the TSO or replacement interval. That said, they do age anyway.

Please consider the age of the harnesses and belts and maintain their condition appropriately. Be safe!

RV-10 Status Report ...jamcgee1978 (Glasgow, UK)

Nessies tail is complete!

Well after 17months and raising 2 kids under 2 i finished the empennage 2 days before my 40th birthday in time to show friends and family what the tail feathers actually were! As i write this the wings have just arrived at the Port of Liverpool (my familys hometown) and so im frantically installing insulation into the shop next week and re-organising in time for the delivery. The process and initial learning curve so far at times challenging has been so rewarding when any builder looks at the final product. Through this website and other builders who have become firm friends you learn, develop and ultimately go on to advise/help others and for me this was the lightbulb moment; I’m becoming a builder! So few pics before I disassemble, re-organise and build on.  ...


HELP Request ... Whole Lotta Shakin' Goin' On!

Aircraft: RV6
Engine: ECI 340 Stroker
Fuel Delivery: Airflow Performance Fuel Injection
Propeller: Whirlwind Constant Speed

Problem: Upon significant reduction in power (quickly pulling the black knob back), as in for landing, if done quickly, I get significant shaking of the engine/prop.

Anyone with any ideas as to what MIGHT be the cause?

Previously, on this plane with a carbureted O-320 and Hartzell Constant Speed prop, I did not have this issue. Don't recall this being an issue with the 340 when it was carbureted and the prop was fixed pitch.

Question for Aeronautical Engineer

I have a Van’s RV-12 that I purchased that has a heavy wing. The RV-12 has the fuel tank mounted in the fuselage offset to the copilot’s side. In addition to the fuel tank being right of centerline I also fly with and without a passenger.

The original builder added a crude sheet metal trim tab mounted under the left flaperon at the wing tip. See top of drawing below... The current sheet metal tab is 1.5” x 12”L and is bent at 45 degrees. In my opinion it is not very efficient because it severely interrupts flow at trailing edge of the control surface. It does however work fairly well.

I want to install a proper servo-driven trim tab with piano hinge so I can compensate for various loading scenarios. See bottom of drawing below… The new inset trim tab will be same dimensions – 1.5” x 12”L.

My question is… will the new trim tab provide same counterforce as current sheet metal tab but with less trim tab deflection?

Aircraft cruising speed is 115 knots.

I’m looking for an educated opinion before I start cutting metal.

Thanks in advance…

New [old] RV-3 Owner

I’m proud to announce that as of earlier this week I am the proud owner of a beautiful RV-3. Chuck Brietigam graciously agreed to let me purchase his baby. I’m convinced this plane has got to be in the top 10 list of best RV-3’s in existence.

For those of you who don’t know Chuck, he is one of the finest people I’ve ever met and is an exceptionally talented builder. While I’m thrilled to own his RV-3, making his acquaintance and now considering him among my friends is the highlight of my purchase.

I’m an Airbus guy by day, so my plan is to turn the plane into my personal Airbus. It’ll be a winter project and I’ll hope to assemble as much as I can on the bench so as to minimize downtime.

I still have my Midget Mustang as of this writing, but I have a person who is interested in buying it as soon as I can repair the paint after some cowling modifications and paint the new RV-8 wheel fairings and brackets. That darned fiberglass sanding, filling, etc. goes on forever and makes a HUGE mess. My hangar is an absolute wreck.

So for right now, my Midget Mustang has a new step-brother.

Happy to be an RV owner again.

Thanks, Chuck, for building a fantastic airplane and for being such a nice guy.

Fuselage Woes

Just felt like venting. I've probably made more mistakes and sent more E-mails to Van's Support while building the first three fuselage subassemblies than I did for the entire empennage and wing kits. So many gotchas! Latest fun: Did the same thing that a few other builders did in this thread: missed the note on the plans that suggests I should not drill through the F-605C bar doubler where it angles down to meet the center bar. I wouldn't have even noticed the mistake if one of my favorite build logs I'm following didn't point it out. Too bad I reviewed the log after drilling the piece. Also, despite trimming the F-605C bar to the exact dimensions called out in the plans, it's end is 1/16" misaligned with the end of the center bar. This piece is a lost cause at this point, fortunately it's cheap.

I used to think I'm being efficient by pre-cutting all the parts I need for an assembly in one go, and I am learning the hard way about delaying cutting or drilling pieces until the latest possible opportunity.

As more and more of the build moves from "follow the instructions" to "read the plans carefully and do everything pictured", what methods do you guys use to ensure you're not missing anything, or doing a step too early? For the empennage and wings, you could treat the instructions as a checklist:

1. Read the instruction
2. Do what it says
3. Inspect the result
4. Check the box and move on to the next line

With the fuselage, a single line in the instructions can be 20 steps, not all of which are obvious before scrutinizing multiple drawings. I like to "follow along" each step with 6-7 other builder's logs while building to try to learn from their mistakes before I do a part, but even that's not foolproof.

Observations after first loooong cross-country (Oshkosh)

Please excuse the long post....After an approx 4K mile roundtrip from NorCal to Oshkosh, I just wanted to share some of my observations on the RV-12. I flew through 14 states, landed at 15 airports, put 40 hours on the hobbs (worked out to about 33 in-flight, 7 on the ground). Cruise altitudes were between 2500' and 12,500', and maybe a little 600'agl scud-running to get out of Custer, SD which put me at a 'cruise' altitude of 6200' My favorite power setting turned out to be 5200rpm, it just felt easy on the Rotax and consistently gave me 110-115kts TAS at just barely over 4gph. I brought a friend with me, so after each fuel stop, we were back at max gross wt.

I am happy to report that the RV-12 is an amazing little plane (as if most of you didn't already know that!). Even as I was building it, I considered it somewhat of a 'toy' airplane that would be fun and inexpensive to fly with a passenger, low and slow, mostly local sightseeing flights. Well the RV-12 far exceeded its mission profile....it was comfortable and capable, even on a trip like this, where I had to cross the Sierras and the Rockies. I am not saying it's a cross-country, high density altitude monster by any stretch, but it really did a great job!

One example....I had to depart Rock Springs, WY at about 3 in the afternoon. Density Altitude was approx 10,400' and I was at max gross. I ran the numbers and figured I should get about 250fpm climb, which was fine. I had a 10,000' runway and no high terrain or obstacles to out-climb. I was able to turn on course towards Devil's Tower, WY and slowly climb up to 12,500msl, which was pretty impressive considering the DA was well over 15K'. I am also super happy that I decided to install the autopilot servos when I was building, it's much better than I am when tracking to a waypoint while holding a steady altitude. It paid for itself on this trip alone.

I had 70 hours on the plane before I left home, so it was already pretty well tested, but the RV-12 (at least the E-LSA version) turned out to be very reliable. Nothing at all against E-AB, I am just saying that if you build it as designed, it's pretty darn good. It's certainly arguable that some of the changes E-AB builders make could make it even better, so please don't get me wrong!

In that first 70 hours, I burned premium unleaded mogas 95% of the time. I pulled and inspected my plugs at 25 and 50 hours, and they were like new. I also did a couple oil and filter changes, exclusively using Aeroshell Sport Plus 4, and the oil looked great at both changes. So, on my Oshkosh trip, I ran 40 straight hours of 100LL avgas. WOW!! what a difference! It ran great the whole trip but I decided that I would change the plugs and oil/filter as soon as I got home. The plugs all had heavy deposits on them, and the oil was much darker (dirtier) and had a 'filmy' look and feel to it. Now I really understand why Rotax recommends 25-hour maint intervals if you run 100% avgas!! I even used the Decalin Runup lead scavenging additive on the entire trip, but it didn't seem to make much difference. In the future, I will use more additive. The bottle recommends 1/2 oz per 10gal of fuel, so that's all I used. They support up to 2 oz per 10 gal, so that's what I will try next time I burn a ton of 100LL.
All in all, what a great airplane!! I still want to build an RV-14A, but I'm no longer in a big hurry to start! The RV-12 can hold its head up high! I would just love to dabble in some aerobatics, and have a solid IFR platform, so the 14A seems perfect for that. If anyone is interested, I put together a 20 minute video about the Oshkosh trip. https://youtu.be/SR69XQj4jZg

Maybe Building a 9A? ...Mark Dickens

Now that I have the -8 done and am looking at the potential of having nothing to keep me busy this winter, I am looking a building a 9A as a cross country machine for my wife and me. The -8 is a great plane and I have no plans to sell it but it doesn't really work for the wife and me as a "go to the beach for a weekend" plane.

So, I looked at the -14...great kit that costs an arm and a leg, not to mention the 390 angle valve engine. I want something I won't feel guilty building. The 9A looks like it might be the best compromise, so I am seriously considering it. Plus I really like the idea of the O-320 and the lower fuel burn!

The Vans website claims that it's matched hole. But I've seen posts indicating that maybe it isn't completely matched hole. Which is it? Would I need to build wing and fuse jigs like I did for the -8? Not interested in doing that again. I just want to build the plane, not build the jigs.



Kids Get It ...vid


New to VAF

Hi to all VAF members,

After working 6 years on an RV-9A slow build and using this forum to answer my numerous questions during the build I am finally going to jump in and start asking for advice/opinions on completing my 9A.

I have purchased a DL-01SS heater box from Vans thinking it was the stainless version I needed, but have now found out that I maybe should have purchased a stainless TG-10 from another vendor.

Can I use the DL-01SS on my 9A and if so does anybody have pictures of the installation showing how the control cable is routed?

Thanks in advance for any help you can give me.

Sad Day ...bkervaski

Just dropped my 14 off for paint ... no plane for 6 weeks


Panel Pics Before and After ...Lufthans RV-4

A friend and I have bought our -4 together, and luckily we both felt the same about our panel. It was full of old vacuum instruments, a VOR and other stuff we felt we'd never use. And so we set about doing a new panel.

Victor uses the plane for local aerobatics mostly, whereas I am mostly doing formation flying with the occasional cross country trip. All strictly VFR. And so we figured we didn't need glass panels. One simple EFIS to have a horizon, plus some reshuffling of the basic round dials that came with the plane. Add Mode S transponder and 8.33 kHz radio (both mandatory here), plus an iPad mini to tell you where you are. Who needs more?

So we put a new panel in CAD, had it CNCd and powder coated, moved the switches to the side panel, rewired 80% of the aircraft and came up with this.


Operating Limitations for IFR


I bought a really nice 9A that was supposed to be IFR Certified. It says in the logs the systems were checked by a certified mechanic and it's "certified". However after digging into the regs it appears this must be noted in the Operating Limitations. After looking at the Limitations noticed it says Day VFR Only.

It looks like I need to get a waiver from the "Administrator". Has anyone been through this process? Is this the correct path?



RV-4 Shots ...Lufthans



August 23, 2018.   Issue #4,638.
  Our son Tate is a senior at Marcus HS here in N.TX, and finally got a slot into the welding class he wanted since being a sophomore.  We drove to Northern Tool Tuesday evening and picked up the auto-darkening hood ($40) and gloves the teacher recommend, and he's off to the races.  Used an Oxy/Acetylene torch for the first time Monday.  The science of the auto-darkening technology is fascinating to me.  1/25,000-second switch time with internal battery charged by the welding light.  Unbelievable.
  His first class project is making me some custom chocks for the RV-6 out of angle iron.  Maybe I can get him to take the occasional pic - getting him dimensions tomorrow.
  The smoke from the fires in the NW has made its way to the North Texas area - hazy skies the past couple of days.  Can't imagine what the haze is like up there. 

Luke, I am your faaaaaathhhhaaaa!
The Tater....student of welding.

From his course outline:
"In Welding, students will be introduced to the basic welding processes and will learn how to cut with Oxy/Acetylene and Plasma rigs. In Advanced Welding, students will learn welding theory, metallurgy and blueprint reading. Students will complete and receive a 10-hour OSHA safety certification issued by U.S. Deptartment of Labor."


New RV-4 Owner

Q: I'm about to be the new owner of an RV-4 picking it up this weekend. Previously I was flying a Sonerai 2L (Poor mans RV-4) that I built myself.

When purchasing an RV-4 is it necessary to notify Van's? or is that just if you purchase a non finished kit and plans?

A: Not necessary but not a bad idea.  Congratulations for getting the best flying two place RV model.

A: Yes you should make sure it’s registered with Van’s if you ever want to buy any RV specific parts that only Van’s sells. I don’t think you can buy RV parts until Van’s has your plane in their database or they won’t support it.


New Guy Checks In


8/22 Update ...j-red

The cowling is nearly finished! With the engine hung, a whole world of new jobs opens up and this is a big one that needs to be done before all the engine systems installation jobs that will come next.

First up was the front fuselage top skin. There's a lot of staring into the fuselage before starting this to make sure that any little jobs related to the wiring, brakes, etc. are finished. Access is going to be much more difficult after this is done. Assured that all was as finished as it could be, the skin was riveted on.


Diagnosing Air in the Brake Line ...lr172

If a soft pedal can be pumped up and becomes hard, that points to seals in the master cylinder or some anamoly with the calipar (warped rotors have similar symptoms). Air in the lines will have the pedal soft until enough pedal travel has occurred to compress all of the air and then it goes hard, often progressively. This should be repeatable any number of times with the same amount of soft travel before going hard. If it is air in the lines, you could pump a hundred times and you'll still have the same amount of travel before the pedal goes hard.



August 22, 2018.   Issue #4,637.
  Tuesday morning I headed out to the airport at 0630 to get in a quick RV-6 flight before breakfast/work.  We had a slow front pass through the day before and had a rare northerly wind.  The OAT was around 73*F when I took off, and as I rose on upwind I saw the image below off to the east.  Over to the lake to get a reflection, then RTB for a breakfast meeting with an old boss.  Catching up.  There was some airplane talk ;^).
  I didn't expect that sunrise, but sure was glad I got to see it. 



Status Report ...RV-3B David Paule

Dallice Tylee came over to help me drill and cleco the LH cockpit side skin. At the aft end there’s a mild compound curvature that presses into position nicely but which I can’t quite manage by myself. This isn’t a kit flaw but a natural part of the design. She pressed a block of wood to the skin while I drilled from the inside, after which she put clecos in. Fortunately she’s both self-employed and a neighbor as well as a pilot, and was able to come over without a scheduling hassle.

The photo shows me yanking out some clecos to fit the LH tunnel side under the skin.


Mothership Stats


Odd Squeak...does it matter?

My -10 has an odd 'squeak', more like a low frequency vibration, when moving the stick rapidly left or right.

If you move it slowly left/right, its quiet...but if you move it rapidly, it has this odd vibration....like a shaft moving through a slightly worn/sloppy grommet ?

I noticed it the other day while on the ground, engine off...maybe been there forever...but I'm not sure.

Any idea what this is ?

I didn't build the plane...it has about 500 hours TT.

Rudder Pedal Technique – Where/how do I place my feet on the pedals ...Dean RV-9

I fly an RV-9 so I’m not sure this would apply to every model but for sure the RV-6 and RV-7.

I flew about 100 hours in my plane prior to adding insulation and carpet to the floor. If I recall correctly I could angle my feet at about a 45 degree angle and hit the bar at the bottom of the pedal (without hitting the brakes).

Now with the added height of the insulation and carpet the past technique doesn’t seem to work.

You guys with insulation and carpet, how do you get to the rudder without hitting the brakes? I’ve been trying to place my feet on the outer bar. That works pretty good on the inside (right) pedal, but the outside pedal has the rudder cable attached there. And by the way I don’t have large feet.

This may seem kind of trivial, but my baby is a taildragger, so it is extra important that I get this right.

Thanks for the thoughts…

PS I realize the picture is of the right side, but you get the point.


Assistance Request - Interesting Engine Troubleshooting Problem

I've been scratching my head, trying to figure out how to help a fellow on our airport resolve his rough running engine. I'm down to only a very few remaining ideas so I thought I'd come to the brain trust for some additional guidance.

- engine is an O-360-A2A with Marvel-Schebler carb, one impulse-coupled Slick mag and one LSE Plasma II ignition
- engine ran fine late last year and currently has approximately 300hrs TTSN, as do most of the components on the engine (save for the carb - see below for additional details on that) and a starter that was upgraded a couple of years ago
- a wing tank fuel leak necessitated a lengthy repair process, with repair timelines exacerbated by a long, cold winter that prevented the use of sealant until suitable curing temperatures could be achieved this spring
- fuel system has been vacuumed clean, flushed with fuel running out at every fitting in the system - literally every fitting has been disconnected to ensure it was not harboring contaminants from the fuel tank work - something on the order of 50 gallons of fuel have been flowed through the system to flush it out
- the fuel tank finger screens have been inspected visually in situ via borescope and found contaminant free
- all fuel line fittings have been visually inspected for leaks and found to be leak-free
- multiple fuel flow tests (fuel line disconnected at carb) have verified well in excess of 150% of max engine fuel burn is being delivered to the carb
- carb has been overhauled by an approved overhaul shop as part of investigation process... then the overhaul shop provided a second, freshly-overhauled "loaner" carb to help with troubleshooting - symptoms do not change with either carb installed
- new spark plugs have been installed this past weekend (sorry, can't remember the plug PN for the Plasma II ignition but they are the exact part specified by Klaus Savier) and the plugs fired by the Slick impulse-coupled mag are brand new Tempest UREM37BY - replaced after I discovered their predecessors were found to have center electrodes badly worn to an oval shape
- Slick mag has had its timing checked this evening - it was at about 24*BTDC and now is as close as humanly possible to 25*BTDC

- engine cranks and starts easily and idles well including an expected slight increase in roughness of idle down at about 650-700 RPM
- engine responds well to smooth throttle inputs
- engine runs well on EITHER the LSE Plasma II OR the Slick mag right up to and including sustained runs at full throttle
- when the ACS key switch is set to "BOTH" the engine seems to misfire and surge at high power settings
- prop is a Sensenich fixed pitch so max static RPM is about 2200 - engine misfiring occurs above about 2000 RPM
- engine runs normally on BOTH ignitions at typical 1700 or 1800 RPM mag check power settings
- no difference in operation is noted with engine cowl on or off
- movement of mixture control makes no difference in the rough running characteristics until obvious RPM drop-off from excessively lean mixture
- engine has been run for a good amount of time with ACS ignition key switch in "L", "R" and "BOTH" positions - engine power is fine for L and R, but the bucking and popping starts as soon as "BOTH" is selected at above about 2000 RPM. This symptomology appears very repeatable.

- engine instrumentation is via a GRT EIS4000 with secondary display of engine data on a GRT Sport EFIS
- no unexpected engine indications are present other than the one known failed CHT sensor
- as expected when the EIS uses a magneto P-lead as its RPM source, TACH RPM is zero when the Slick magneto P-lead is grounded via the key switch
- operation on each single ignition system shows EGTs rising, and declining again when BOTH ignitions are selected ON
- when the engine is misfiring on "BOTH" ignitions, EGT drops slightly
- TACH signal input is from the left mag P-lead via a series dropping resistor - I haven't cut open the heat shrink on that resistor yet but since it has worked for about 300 hours I'm suspecting the resistor itself is not the source of the trouble
- other recent work done on the aircraft includes replacement of alternator field wire and its associated firewall feedthrough when engine run-up in the spring time resulted in a popped circuit breaker caused by the field wire having chafed through to ground at the firewall penetration

At this point I'm nearly out of troubleshooting ideas. Since the engine runs very well on each individual ignition but runs poorly when both ignitions are firing, I've been looking for a common tie point between the two ignition systems as a potential cause. The only thing that comes to mind is the GRT EIS tach signal pickoff - its wire is an unshielded 22ga Tefzel wire which is bundled alongside the other wires going to the ignition switch. The resistor connection is made literally right at the ignition switch terminal. I'm wondering if that unshielded tach sensor wire could be coupling p-lead voltage spikes into the LSE Plasma ignition, causing the Plasma ignition to misbehave. Has anybody seen this before? The magnitude of P-lead voltage spikes would be expected to increase with engine speed so this might explain why trouble doesn't occur until higher engine power settings.

Any well-considered suggestions from this esteemed group would be very much appreciated. Thank you!

First Flight N975G ...Ron Gawer RV-12

I am happy to say that my RV-12’s first flight was a successful one.

Having my wife on the ramp watching (and quite nervous about the whole thing), I simply made one trip around the patch to prove the controls work and the airframe worked well. I’m happy to say it performed very well, light on the controls and flew straight and level just touching the stick - and a pleasure all in.

My oil temp did get above 210 in flight settling at 214. This is frustrating as the oil cooler is stuck to the front cowl with a full opening. I can only imagine that it’s somehow undersized. I’ve contacted Bill at Airflow and gave him my data and he is going work out a different cooler for me (side note: talk about customer service! I emailed him on a Sunday and he emailed me right back with advice and request for data.).

Note that I never got my revs above 2400 - the airplane accelerated and lifted off a lot faster than I thought it would and I didn't even get the throttle all the way in yet. That, and knowing that oil temps could run high, I just left it at partial throttle. I chuckled to myself in that going from my Baron to this is like going from a deep draft vessel to a jet ski - super responsive. I pulled it back to 2100 at right crosswind and left it there until pulling back for landing. I landed a little fast, but I had 12G18 30º off from the right and wanted to carry a little extra. I’m pretty happy with my first landing in an RV-12. I did not experience any roll or pitch issues with flap extension that I’ve read other folks experience, so that’s good too.

I already have a short list of tweaks going, but it was a good first run. Enjoy.  Videos


RV-7 and Life PIREP ...rmartingt

Wow, so I've been a bit of a slacker at updating the thread... but in my defense, we've had a heck of a year or two. A few of the guys at FFC have probably heard some of this...

Starting in 2017, my wife started going to Emory in Atlanta for her epilepsy. After lots of testing, and far from just getting the second opinion we were looking for, the doctors up there decided that she was a candidate for surgery! Apparently they evaluate a couple thousand people a year and only one or two hundred are viable candidates. That was unexpected news, to say the least--we hadn't even considered that as an option, much less any hope that she could be "cured".

In January of this year, she had probes inserted to nail down where the seizures were originating, and then on April 19th she went in for surgery to have that part of her brain removed (sounds scary, doesn't it?).

You know how they always tell you before surgery that "there's a small risk of (serious thing)"? Well, she caught that risk. During the surgery she suffered a stroke in the part of her brain that primarily controls motor function, and when she first came out of surgery she couldn't move anything on her left side. Those first couple days were probably the scariest of my life.

Fast forward four months.

Two weeks of intense inpatient therapy had her walking out of the hospital, unsupported. A couple more months of outpatient therapy back home has her running around kicking a soccer ball with our son. We're hitting the gym four days a week and she's back up to (or exceeding!) where she was before her surgery. I think her progress has exceeded even the best expectations of any of her doctors or therapists--so much so that as of yesterday she's done with all of her therapy.

And over the past couple of weeks, she's been coming out to the shop to rivet with me!  Her therapists consider it a good therapy exercise and she's enjoying it, and with her help I'm ready to flip the canoe as soon as I get the cowl exit heat shield riveted on. I'll have some pictures up after the flip.

Oh, and just before her surgery, I also picked up an engine core, so to speak--an O-360-A1A, disassembled and tagged minus cylinders. An experienced local A&P will be helping me assemble it when the time comes.

But the best part of all this? Still no seizures She has at least a couple more months to go before we can start working on getting her driving again, but the longer she goes the less likely it is she'll ever have one again.


Canopy Frame Groin Punch! ...dwrand [ed. I love that thread title. v/r,dr]

Well I was ready to rivet the skin to my canopy frame today to get ready to glue the canopy to it next week. I had noticed the fit on the right side had changed a little, but I thought it had to do with the 3 strengthening pieces between the frame and skin. I put the blank panel in for the first time with the canopy frame installed and there was a huge gap near the middle on the right. I discovered the tube on the frame had cracked. Talk about a punch in the groin!! I have an email in to Vans to see if it's something that could be welded or if I have to replace it and start over. UGH!! This was also the first time I realized that that tube and the huge gap between it and the skin on the outer edges are visible from inside the plane. Now I know why guys use fillers to fill in that gap to make it look nicer. For some reason I thought that tube was behind the panel when the canopy closed.


RV-10 Status PIREP ...Brantel

Emp/tail cone kit is scheduled to arrive on Thursday.

Garage has been cleaned out and set back up as an airplane building shop!

Airplane building tools have been recovered from the hangar.

A million bucks have been spent on replenishing consumables and a few extra tools.

The build blog has been established and I am getting the hang of keeping it updated. (Link in signature)

Looking forward to getting started!

Here are a few things I want to address while building the tail while it is all wide open:
•Pitch servo mount
•Yaw damper servo mount
•Rear air vent mods
•Rudder trim? Maybe

Anything else I should consider?

Status Report ...Mark Ciaglia RV-10

I just passed the two year build mark. It has gone faster than I could have ever imagined.

Completed to date:
QB wings (75% done with remaining tasks)
SB Fuselage (getting ready to fit cabin top)

Some points I like to make:
1.) Thank you to DR for this site. I log on daily and learn from the immense amount of information here. The builders that have come before me have paved the way to address issues that are easily taken care during the build.

2.) I am glad I have primed. I used Azko and it was a little bit of work setting up the paint tent and all the associated prep work. But here in Houston, the humidity can be brutal.

3.) I am nearing the end of formal metal work and getting readu to dive into the composite world. Please send me prayers.

4.) I have realized Stein "Will not be happy till I'm broke" I have done the order from Stein on Monday...do work Monday night...realize you need something...order from Stein on Tuesday. I think I will single handedly fix the USPS deficit.

5.) I want to find the team that built my wings in the Philippines. I will gladly send you a case of beer, bottle of scotch or what ever you want. The QB wings are such a luxury. My hat off to you guys who do them the SB way.

6.) I have decided the plane will most likely be done Tuesday... I just dont know what month or year. Thats what I tell everyone

7.) Thanks to my wonderful family so far. I have managed to keep my anticipated pace of an hour every day (average) 2 years down and have worked a total of 731.65 hours on it. I haven't missed a single family function due to building and my kids love being part of this.

Time to get back to work.

Pneumatic squeezer problem ...Ed Wischmeyer

So I’m using my pneumatic rivet squeezer for the first time in maybe 15 years (!). The ram, fully retracted, extends 0.3”, and fully extended, the gap (with no set installed) is 0.4”. I took the yoke off and the ram out, and it’s a fixed ram (non-adjustable). So I’m wondering if the squeezer has something wrong inside causing the ram to be too far extended, all the time… Hopefully I’m doing something dumb that I just don’t remember.

There is no manufacturer or model number on the squeezer body. And I do have a full bunch of flat sets of various thickness.

I’ve looked briefly at the Cleaveland too youtube video, and although that reminded me of some things I’d forgotten, it didn’t help solve my problem.

So is there something internal that needs to be looked at? I'm not looking forward to taking it apart but can surely do that. And there are no indications of rust or sticking.

7A Builder Status Report ...jcarne

After match drilling the top skins I decided to work on installing the steps before moving to the baggage area. The steps aren't as difficult as I thought they were going to be but still time consuming since you have to do the on off shuffle quite a bit.

I can't get the rivet layout that the drawing specifies due to the massive weld Van's uses now. I backdrilled two holes in the plate that coincide with two existing rivets in the F-724 baggage ribs. One of them is close to the weld, I may have to grind it ever so slightly so that the rivet head sits flush.  ...


Way to go JERRY

Two RVs flew in the Kathy Jaffe aerobatic contest this weekend in NJ. Jerry Esquenazi and Oliver Spatscheck made a fine showing, with Jerry coming in 1st place in Sportsman. When the regional standings are updated and posted in the IAC website, Jerry will also be in first place in the southeast with three contests, and Randy King in 2nd place. Our prediction that RVs will start to dominate the Sportsman category is beginning to show.

Oil Cooler Fittings PIREP ...RV-14E input

Where to Mount a RV-4 Canopy Breaking Tool ...ArlingtonRV input

I mounted mine, one of those automotive hammer dealies, to the side wall below the roll bar. It is accessible from both seats.


Some minor VS skin damage

I'm in the process of setting up my workshop and I've been keeping my skins in the box in which they came. Well, I noticed a bend in the lower right corner of my VS skin and discovered that it had punched right into the side of the cardboard, resulting in an about 8 degree bend through the first prepunched hole. An amazing discovery when I just got the kit a week and a half ago and haven't even received my tool kit yet

I took a wood block and a mallet to it and gently tapped it back into shape, but there's still a tiny amount of deformation to that corner. I don't think it will affect anything structurally – it's bent slightly inward toward where the VS spar will be and the damage is really only visible from a distance if the light catches it. If anything I think it's just a cosmetic issue at this point.

I know the usual advice is to "flatten it out and build on", but does anyone recommend replacing the skin? For $85 plus shipping I don't know if it's worth scrapping an otherwise perfect skin for one tiny corner, but I'm open to suggestions.

Good morning folks,

I know this note on page 33-04, "Tighten the nuts and bolts until they are finger-tight DO NOT use standard torque values," applies to the nuts and bolts attaching the rudder pedals. Does it also apply to the nuts and bolts attaching the brake master cylinders, or should those be torqued to standard values?

Plenum Cowl Input ...DanH

There is no "perfect" size; any size covers an operating range. All the data says low Vi/Vo is superior, so when in doubt, go larger. Experimentally, six inches diameter seems to work well with the 390 and 540. The external diffusion (pressure rise in front of the inlet) is frictionless. The practical limit seems to be set by external drag, i.e. flow separation as the excess air flows from in front of the inlet, to outward and around the inlet....something like this


Right Brake Won't Bleed, RV-6A  ...petehowell

Here's the situation. Buddy has an RV-6A. We found a leaking, cracked flare at the right caliper and fixed it. Having a whale of time getting the air out of the right side brake system when we bleed. Pilot side brakes only. Has a soft pedal that can be pumped up to solid, then goes soft in a short amount of time. Left side has solid pedal, no problems.

Here's what we have done. Garden sprayer pressure bleeder from the bottom up. We've run several qts thru the system and out thru the reservoir. No bubbles coming out at the reservoir. Still a soft pedal.

We took the pressure side line off the master that goes over the top of the pedals and tried to get any air out of that - then rebled from the bottom up - soft pedal.

Replace master cylinder on the right side, re-bled, still soft pedal.

There is section of pressure side line that goes from the flex hose to to solid tube then up and over where the battery box used to be then on to the gear leg bulkhead fitting. That area looks ripe to store a bubble, any ideas how to flush it out better?

There are no fluid leaks we can see anywhere. Any tricks we are missing or areas to inspect further?

Thanks for any Ideas.......


About to Make First Cowl Cut - Seems Extreme? ...IowaRV9Dreamer

I'm finally going to start work on this cowl from 2010. The first step is apparently to get the front and back to mate and form a 13" circle. The manual provides some high level guidance - basically trim it till it works.


How to "Keep Up" with a Piper Tomahawk ...AlexPeterson

A friend visited us this past weekend, flying up in his club's Tomahawk. When he left, I decided to escort him on his way in the RV6A. I gave him a couple minute's head start, and took off, keeping him in sight. OAT was around 90F, so I knew I wouldn't be able to stay behind him at only 70 knots long before engine temps climbed. After a minute or two, while he was climbing at 70KIAS, I sped up to 120 or so and zig-zagged behind him, all the while climbing above him. I reported to him that he was looking at a headwind of 30 knots at 3.5'k. I climbed to 5.5'k and reported to him that the headwind diminished to about 10 knots there. I then descended back to his altitude, flew on his wing at 70 knots again for a minute, then buggered out back to base.

Here's the ground track:


A Little More Playing Around w/the DIY Lifting Creeper Idear

...updated pic

F=M*A.   What kind of pulling power is going to be needed to raise it when the chair is (almost) flat.  I would think it might be pretty hard, if not impossible, to lift from flat with a person lying on it.  Stuff to work out...

Some more picture detail with fixtures from an old garage door.  Fun to play with...

RV IAC Aerobatic Competition Standings - 2018

Galen Killam and Charlie Teeuwsen both put up some decent scores recently. Charlie placed third in Sportsman at the Can-Am Championship, securing a third place overall standing in the RV Competition Standings. Galen is holding onto 4th place in the Standings now.

There are still plenty of contests this season. I count 15 regional contests left, plus the US National Aerobatic Contest in Oshkosh (Sept 22-28).


Motherhip Ping...



August 15, 2018.   Issue #4,632.
  Has anyone in the RV world built a DIY lifting floor creeper?  Something like the guy here, but with a twist.  There are a few threads about people buying lifting creepers, but I was specifically looking for a DIY, made with 2 X 4's and bolts type thing.  Workbench like...
   My little mod idea:  I would like to have a boat winch type setup on the right side just about where my hand would rest.  This so I can crank it while laying down to lift the creeper bed slightly. I don't see why the crank assembly couldn't stick up a little bit to accommodate a standard winch/handle. Something like the Photoshopped Frankenstein here that I hobbled together.  Obviously the creeper wouldn't be this polished - more like a wooden workbench.
  You know how you need different heights when you're wiping the leading vs trailing edges of your taildragger RV?  And the bottom of the cowl vs the underside of the HS?  Trying to address those things using the RV Community Brain Trust.....and wood.
  Something like Sam did with his DIY tail lift project, but laid down over on its side.  Absolutely if I can work up some plans and a prototype with the help of others, I'll host the parts list and plans here somewhere if nobody else wants to.
   I started a thread on it to hopefully get the ball rolling.

I've got a Builder Number! ...Kenny Cahill

After a few weeks of tooling up, bench building, and and working through the practice aileron kit, I've placed my order for my empennage. I'm extremely excited about what lies ahead.

I'm also registered for the sport air workshop on RV assembly in September (Frederick, MD). Hoping to continue sharpening my skills there but also get the bigger picture of the end game (finishing, paperwork, inspections etc.)

Jason Ellis got the referral for his awesome youtube series filming his RV-10 build. I watched most of his content as I deliberated if this was the direction I wanted to go.

Look forward to participating in this community!

Panel Update ...mwardle7

Greetings! I thought I would post a few pictures from a recent panel upgrade for those of you who may be looking for ideas on how to expand the features available on your RV-12 panel.

I have the G3X Touch with autopilot, but I do not have a separate control box for the autopilot. I like the utility of the Blue "LVL" button that is available on the separate control box for engaging the autopilot in straight and level mode, so I added a switch that is wired to a discrete input on the G3X for AFCS Level mode. The switch is the blue version of the red autopilot disconnect switch that Vans uses; here is a link to the part number on Mouser: OTTO LP9-11112J26. I had custom labels made a local trophy shop.  more

Step 0.1: Book the trip to Aurora ...joe gremlin

I've had a hankering to build some kind of RV ever since I started working on my private cert back in the late 90's. Never had the means or the time or the space to really consider it.

Going to be turning 50 next month and I'm finally to the point where I've got the time and the space. The money? Well we'll figure that out as we go. Wife has about a year of school to go on 2nd masters so not planning to start anything until next summer.

I've already booked us a room in Appleton for OSH next year so we can see all the Vans stuff as well as the competitors. But today we just booked a trip to Portland for my birthday next month. The plan is the to do a factory tour. At the very least we want to see how we fit in the 9 vs the 14 vs the 10 while we're there and take a demo ride if able.

Planning to go see the Spruce Goose while we're there and then spend a couple days seeing the Mt St Helens area.

Is there anything I should make sure I see/do while at Vans and is there anything else we should try to see or do in the area while we're there?


RV-3B Status Report ...David Paule


Serious Control System Issue ...jwilber RV-10

Doing my first annual. When checking the elevator control in the tunnel I found the jamb nut was loose about 6 turns. Upon further investigation I found that the F-1065 cross bar was scraping the safety wire which in turn had worked the jamb nut loose. This happens only when the stick is pulled all the way back and while all the back it moves left/right -- exactly what you do when landing.

I know for a fact this was not scraping when I finished the build. I believe the push tube just twisted enough to bring the safety wire straight up top. So this had to be fixed. My plan was to first remove the bearing from the assembly, loosen the other end and roll it to put the safety wire on the bottom so it could never interfere again. Then I was going to adjust the segments as necessary to prevent any lingering interference. .... Well, as soon as I started removing the nut/bolt holding the rod-end bearing, the safety wire fell out. The safety wire loop on the bearing side had broken and the safety wire was being held only by being compressed in the assembly. In other words, it was not doing anything at all.

This part in the RV10 is on-purpose designed to have the rod-end stick out far more than half the threads in order to prevent interference with the tube itself. The safety wire is meant to prevent the tube from ever turning and working loose. I know I built this to plans and had it checked by another builder at the time.

Based on this experience I'm not happy with this design. In my case the tube twisted enough to put the safety wire on the top where it was then the cause of the interference. Further, I believe the constant working of that safety wire back and forth during landing (especially when forward CG - like flying solo for the first 40 hours) caused the safety wire to work harden and break where it went around the rod-end. I'm not 100% sure what I'm going to do to prevent this from happening again, but I'm considering safety wire on both sides in such a way to prevent the push-rod from rotating in either direction.

I'm not special so I'm assuming I'm not the only one where this has (or is) happening. I suggest everyone have a careful look at this next time you have the tunnel exposed.

In my case I caught it while doing a control system check with everything opened up for my first annual. When I had the stick full aft and moved side to side I could hear something scraping. And that lead to this find. ...

Oil leak help

It looks like there is an oil leak coming from under the lower hold-down clamp of my right mag (slick). Looks like the oil is seeping through the stud and out from under the hold-down nut. I recently changed oil and adjusted the timing of the right mag. I have not flown since then. After finding the leak on the floor - many drips worth over the course of several days, I cleaned it up, hoping it was just some drips from the recent oil change. Days later the tiny puddle is back. I torqued to 17 ft-lbs after adjusting the timing according to the lycoming manual. Yesterday, I loosened the nut, cleaned up the oil seeps again and re-torqued it. Haven't checked it yet today.

Does it make sense that oil would seep from this spot? I read on the Google that there has been some issues in the past with torque on these hold-down nuts and cracking somewhere. Any suggestions or thoughts?

New RV Owner

I have finalized the purchase of an already flying RV6A, and will be going out to pick up the plane this weekend. Thanks to all who have helped me get connected with a ferry pilot/transition trainer. He will be flying most of the way back home (from California to Louisiana) with me and doing the training along the way. The plane is a 2013 completed model with skyview touch PFD/MFD dynon AP with a GTN650 navigator. I can't really describe how excited I am about owning my first plane and the trip back to get her home.

I wanted to start this post so I could post pics of the pickup and the trip back.

Multiple fuel flow transducer failures

I have the EI FT60 'Red Cube' flow transducer mounted in the center tunnel up near the firewall, just forward of the electric boost pump. It's the most inaccessible component on that entire airplane, and I neglected to install an access panel when I had the chance.

It failed after only 20 hours. I spent nearly 3 weeks taking everything apart to get at it and replace it, and the new one functioned just fine after several tests. That is, until I got the entire airplane put back together and had it out on the tarmac for engine startup. That's when the new transducer failed, with essentially zero hours on it. I had to walk away before I took a crowbar to that **** airplane.

This transducer is not in a high heat area (125 degrees F has been the max tunnel temp so far) and vibrations aren't excessive. Does anyone know what would cause these things to fail so quickly? I consider the flow sensor as a mission critical piece of equipment - the plane won't fly if it's not working.

P.S. - Do yourself a huge favor and install an access panel in the tunnel everywhere you have a critical piece of equipment. You will thank yourself later.

Goofed Nose Rib - Next steps? ...RV-14

Section 8 (Horizontal Stabilizer) Page 08-11, Step 3.

Hi All,
I reached out to the mothership a few days ago, and while awaiting a response, I'm very interested in what you all think.

I’ve riveted the middle four HS-905 nose-ribs to the right and left skin.
On the last of the four ribs, the last rivet, I didn’t like the flushness of the manufactured head so I drilled out the rivet.
The head snapped clean off and when I used the punch on the rivet body, it bent out the flange on the nose rib a bit.

I tried using gorilla tape to hold the flange to the skin when re-riveting, but not with much luck; it sticks out. When I re-rivited, it bulged between the two parts.

What should I do about that last rivet? The only thought I had is to drill out the entire rib and replace with a new rib, but I’m quite concerned about ruining the entire skin by having to perform so many drill outs. And then making a small problem a really big, painful, expensive problem.


Those pesky leading edge rib to spar rivet-conquered!

Those "solid" rivet call outs for riveting the leading edge assembly ribs to main spar...most folks acquiesce and pull LP4 pop rivets or such. I challenged this task and I engineered a way to stick with the vans design! ...by driving the impossible to reach SOLID rivets in the leading edge ribs.
QA results: No smiley faces. No bent over shop heads. No gaps between ribs n spar.

What? How?: I drew up and tolerance'd a big steel block that holds five AN470 rivet sets. Imaging a rectangle block approx. 7" x 2.5" x 2.5" weighing about 13lbs or so. Placed this engineered tooling inside the leading edge assembly. Imagine if you have the wing in a jig/stand at this time, like you are supposed to at this phase, then this block lays inside and on top of the main spar. Then I back riveted vertically from the wing's aft side with a 12" offset back riveting set. Pretty awesome.
I was able to coax the Vans team into sharing with me actual dimensions for hole locations! Then I tolerance'd the tooling for the machinist.

Essentially this process is a heavy steel block (heavy mass desired) to back rivet against. And use a medium sized automotive ball-joint spreader as a pry bar. This remedied the long reach and clamping need. Basically my mission was to harness the easiest rivet method...back riveting, for purpose of best possible Quality.

I'll try to add photos here. But I am willing to align with anyone and lend you this tooling...even give a helping hand.
Sticking to the drawing and managing quality results equals finesse. An awesome feeling.

RAF camping trip at Creighton Island - Sept. 28th & 29th ...Bill

On the weekend of September 28th & 29th the RAF (www.theraf.org) will host the final Creighton Island fly-in camping trip of the season.

You are all welcome to come but I do ask that you RSVP to brepucci (at) theraf (dot) org. (Yes, No, and Maybe is acceptable.)

The island has good, clean drinking water and showers with hot and cold running water; however, you will be responsible for tents, sleeping bags, chairs, food, etc.

We hope to have a Pig Pick’n with a locally harvested swine on Saturday night. If we don’t have any luck, we will run into town and pick up supplies for a low country boil.

In addition, if you are a musician and can bring your instrument(s), please do so. We are trying to arrange some entertainment but the more the merrier!

As I said before, all are welcome but we ask that you RSVP, review the safety briefing, and watch this video of the approach, landing, and takeoff. (The camera ship was a certain blue and white RV-9.)

The runway is bumpy but I have seen an RV-9, two RV-10's, and an RV-4 in there.

We hope and pray for good weather and good times.


VPX and Contura rocker switches

After several threads on this subject showing some confusion, I made this schematic to help the non-expert in wiring builders connect Carling Contura switches to a VPX unit.

The big secret is to use double pole switches - labeled DPST - to remove any use of diodes with the VPX, and two independent lamps/LEDs if you want illumination.

I hope this schematic will help others -

RV-9A Around The World Update ...John

Due to concerns of potential damage to the plane from Hurricane Hector at Hilo, I relocated "May" to the island of Maui. Thanks to the VAF community (Ed, Scott, Eric, and Brad) I was able to secure a hanger at Kahului Airport (PHOG).

The winds aloft forecast for the Hawaii/California flight does not look favorable for the next two weeks. I decided to fly home commercially, rest and prepare for the final leg of the trip. When I return to Hawaii on August 21, I will complete work on the aircraft, fly back to Hilo, and wait for right moment to fly the 2000+nm to California.



Sky King Featured on the Garmin Blog

I'm proud to say I'm one of I think 3-4 people to solo this particular RV-8.  Yes, it's a pretty awesome flying plane.  Don't compliment him too much if you read this piece - it'll go to his head and we'll never hear the end of it at lunch ;^). 


McCauley Hub Question ...AX-O

I have been doing research on the McCauley hubs. Lots of info here but seems to be potentially obsolete based on the dates of the threads, people gave up on trying the combo on RVs or folks figured it out. I also found info on the McCauley website.

I am working with Catto propellers to develop/test a constant speed prop for RVs.

I cannot find any engineering drawings showing dimensions between the prop mounting flange, spinner back-plate mounting flange and/or the differences in dimensions between hubs. All I can find in their 500-plus-page doc is 4.5 or 6.5 inches from prop flange to center of the blade. I did call McCauley but long story short, no help.

Does anyone know where I can find that info? I was thinking of using the maybe the C211 or C214 hub, or the C220 hub since I have a 4-inch extension on my plane.

Thanks for any info that you can provide and for minimizing the thread drift.

Craig has been running the first constant speed prop on the test engine/stand for several weeks now. Hope to be flying the RV version in Jan if I can figure this stuff out (fingers crossed).


Looking at the -12, couple questions ...Eric B

I *was an RV-10 builder, but life came along and now those little feet need something to do. Why not build a plane?

First, I sold all the tools along with the kits and components a while back but the longeron yoke was my favorite for the pneumatic squeezer. Would a pneumatic squeezer be a benefit on he RV-12? I'm thinking of all the nutplates. Would a longeron yoke be useful for those?

Secondly, how much room is there behind the panel before you get to the subpa el? Looking to add an IFR navy to the mix, maybe Avidyne and the dimensions say it is 11" deep.

Thanks in advance! Looking forward to getting back. Hopefully.

Gas Tank Update ...DrillBit

Since a mod moved this to an archived forum* (originally posted to the temp section), I best finish the story in case you, Dear Readers, are wondering what happened...

To get gas to the boost pump, I slid some tygon tubing over the right tank vent and gently pressurized it, blowing into the other end of the tubing. After a short time, gas came siphoning out. Switched the fuel lever to off and let things sit awhile. Fired up the pump (wired as it was originally--the right way round ) and shazam, the pump was pumping.

However, despite the healthier sound coming from the dry pump, fuel flow read 0.0 gallons per hour (could have been firkins per fortnight, for that matter). Tried switching the Dynon EMS configuration to the second flow meter input pin in the Skyview EMS and once again, I had not hooked it up wrong. Easy to try since a software setting is easier than cut wires to reverse. (Besides, the second pin is for a tank return line and reads the opposite of fuel used!) This time, I was smart and decided to read up on troubleshooting Red Cubes before cutting wires or taking apart any plumbing.

In the meantime, I went ahead with baseline fuel flow tests with the a/c nearly level, about +1 degrees. Weighed the receiving jerry can with a fish scale before and after a timed pumping interval. Right tank: 1.9 lb in 30 sec = 228 lb/hr; left tank: 3.6 lb in 60 sec = 216 lb/hr. For an FI 160 HP engine, FAA recommends 1.25 x 0.55 gal/HP/hr x 160 HP = 110 lb/hr. Plenty of margin when level--we'll see what happens when tested at the "anticipated maximum angle of climb."

OK, what about the dang flow sensor? Dynon fora recommended grounding the yellow wire sensing line that goes to the Red Cube. If all is well in the EMS unit and wiring, tapping ground sends pulses and causes the fuel flow counter to advance--which it did. OK, if 12V and Gnd are good (red and black wires, respectively), then the Red Cube has a stuck impeller, dead electronics, or whatever. In the course of cutting the heat shrink away from PIDG knife splices, the red wire pulled out of its knife. Turns out the terminal had cracked too. Odd, first time I've had a bad crimp, or mishandled the terminal, or it had a latent defect to begin with?

Anyhow, the upstream black wire was solid to FoT ground and the red wire had +12.2 V with the bus turned on. I decided if one knife splice was bad, they all may be, so I changed to Dsub barrels and pins to make new splices. Once it was all together again, the fuel flow sensor was alive, and showed nearly the same flows (+/-1 gph) as the measured values above. My supposition is the sensor wasn't getting power before; works like a champ now.

Thanks everyone for the suggestions and advice. I didn't try pouring fuel back through the fire wall, since I had rigged up an overflow line and lashed it down with tywraps.

*I suspect it may have been the Lord Mayor of VAFdom himself, DR, since the flow issues made the VAF News front page. Note to self: for maximum VAF exposure, compare RV systems with health issues of men of a certain age...  [ed. It be I.  v/r,dr]


Fuel Pump Update ...Steve Riffe RV-8

After a flight last week, I noticed a drip from the fuel pump overflow. It appeared to have leaked enough to leave a small streak on the lower fuselage, although I never had any indication of a fuel pressure fluctuation. After reading this thread, I could hardly wait to replace the pump (NOT). I picked up a new pump at Air Power in Arlington. I removed the cowling and set about removing the old pump. Access is rather limited, so I removed the scat tubing for the cabin heat and removed the lower line from the oil cooler. I removed the pump overflow tube and the fuel lines from the pump. I zip tied all of these lines to various places on the engine mount--this helped free up some space. I cut the safety wire and removed the bolts. I found that a ball end hex tool was the only way I could get on the bolts. So, old pump off, then cleaned off the old gasket material from the engine with a scraper and some disc brake cleaner. At this point, I called it a day. The next day, I ran some string around the rod that operates the arm on the pump and clamped the free ends to the plate where my GPS antenna is mounted. I held my finger on the rod and slowly rotated the prop until the rod was fully retracted. Looks like the string will hold it in place. I used the old pump as a test to determine how best to position it for the installation. After I was satisfied I had found an acceptable method, I proceeded with the new pump. I coated a new gasket with permatex #2 and stuck it on the pump. I also coated the bolt threads with permatex thread sealer. I inserted the pump and rotated it about 30 degrees counter clockwise. This allowed the arm to fit under the plunger and the inboard bolt to engage. I gave it about 3 turns. For the outboard bolt, the pump has to be rotated clockwise to line up the bolt hole. This was the difficult part because the plunger rod must slightly depress the arm on the pump--and that arm has one stout spring! After several tries, I got the bolt started. I pushed the pump flush against the engine to ensure the arm was under the push rod, then tightened up the bolts until there was less than a 1/4" gap between the pump and engine. I pulled the string out and finished tightening the bolts. The safety wire wasn't much fun either, but I got it done. Re-attached all lines. Ready to test run and check for leaks, but now it's raining--will do it tomorrow. I spent about 4 hours on this project--I stand in awe of the gents that did fun task in 15 minutes and 35 minutes. Thanks to all for the tips found on this thread!

RV-3B Status Report ...David Paule

Well, with a bit of help from Sam Ritchie, local RV-10 builder, we glued the RH forward side skin on today. This is the cockpit side. This was the culmination of considerably more effort than had been apparent. Among the things that delayed this were:

The skin had been primed. The paint job turned out to be extremely rough, so I removed it completely, as I've mentioned.

With all the various overlaps of the construction, I had to add a lot of shims in a number of places. You may have noticed that.

I had to decide what I was going to do about the forward turtledeck later one. This is the one that goes between the firewall and the panel on top. According to the plans this overlaps the side skins and is attached with #8 screws and I believe the RV-4 is similar. If I were going to accept the overlap there, I’d have to fit those #8 holes in between the -4 rivets at the forward end and those rivets are spaced about 3/4” apart while the screws are roughly 2.5” apart. Worse, I’d have to drill, countersink the longeron and dimple the skin. That would only add a day’s delay. Still, the panel attachment meant that the position of the screws at the aft end would need to be a SWAG and the integration of the cowl cheek flanges would not happen for a considerable time down the road.  ...

Aileron - Repair or Replace?

Hi All,

This weekend, my left aileron experienced what I want to call “hangar rash”. I had the aileron off of the airplane, laying on a table, gust of wind came thru the hangar sending it to the floor. Damaged the outboard trailing edge and a small dent with a crack in the skin on the inboard end. For the dent damage, i figured I would stop drill and fill with some sort of filler (not Bondo). What is more challenging is how to repair the trailing edge that appears to have taken the brunt of the fall. I attempted to "pull out" the crumpled aluminum edge ever so gently but in doing so, a crack/tear appeared along the trailing edge. So, I stopped. Here’s what I am facing. First the trailing edge of the aileron;


Stick Bending

Hi Guys,
I'm looking at getting my stick bent with the 1.5" offset but I'm
a little concerned with making it work with the otto grip.

3 questions

How far aft does the stick go in relation to the seat pan?

Does the stick travel underneath the bulkhead brace forward of the panel?

Judging by the photos and the bottom side of the grip am I going to create problems with the seat cushions later or can they be recessed out to suit?

With the stick mocked up with conduit I can get my thumb on the top hat and clear the bottom side of the panel but not the forward brace.




8/5 Status Report ...j-red

Finally had a chance to get my engine built and hung. This is the second lycoming i've assembled and it was definitely much less intimidating this time. Just follow the overhaul manual carefully and check off each step as it is accomplished.

The engine assembly isn't completely finished, but done enough to get it out of the church gym so that VBS can commence next week!

List of things to do include:
  • Purchase 5 shorter pushrods for valve clearance
  • Install intra-cylinder baffles then oil drain tubes
  • I'm going to hold off installing the superior cold sump until a new fuel pump gets here... should make it a little easier to keep the plunger in the right spot while putting the pump in.
need 5 shorter pushrods for valve clearance, and am waiting until my fuel pump gets here before installing the sump

Next major job: the cowl!


AeroLED Shielded wire and routing

There's a crop of my light section of wiring. The Yellow, red and blue lines off to the right go to VPX pins. The jist is the VPX controls the wig-wag, recog stuff so each Landing light is wired separately to the VPX, however the Taxi wires will be joined and put to a single pin.

For the Nav lights and Strobes all three get wired together to include the green sync wire and put to a pin for Strobes and a pin for Nav.  ...

Another flying RV ...Claude Pitre

Shortly after 9:00 this morning, on a beautiful day, RV-9A C-GCPT did what it was designed and built to do - fly! I rode along in the left seat as my engine builder - who has 14,000+ hours in about 170 different aircraft - handled all of the flying. We backtracked runway 17 here at CYQF (Red Deer, AB) to have all 7500' available. We only needed the first 1000' and then we were off and flying. The aircraft flew true hands off on the climbout and handled very well through the hour long flight. As expected, the new engine ran hot (CHT ~425F) for much of the flight but settled down near and below 400F after 40 minutes or so. Flight was done at or above 75% power.

We ran into an engine issue as we started our descent that resulted in losing power in cylinder #1. This was quickly diagnosed as a leaking injector line and we mitigated the fire risk by keeping the airflow high in the descent. Power came back as we landed without incident. A quick check after the cowling was pulled revealed that the nut at the flow divider had completely backed off and slid down the line. The flared end was still firmly against the fitting, so the worst it got was leaky. Certainly a serious issue that should have been caught by either of us.

Not much else for snags, we'll get it fixed up and back out for flight number 2 later this week.

Not much luck with video, but here are a few pictures from just before the flight.


Airflow Performance pump failure ...Greg 9A

Well, actually not so much a pump failure, as a pump failing due to something else, but I still ended up with a dead pump.

I run 91E10 mogas in my system, and thought I had cleaned out all the natural rubber seals and components on everything to avoid problems with the fuel attacking the natural rubber seals. I missed ONE O-ring on one of my fuel filters, coming in from the right tank prior to the pump, and after 285 hours it finally degraded to the point where it was leaking. At first I noticed a very faint whiff of fuel smell, weak enough I could have dismissed it as a figment of my imagination. A couple flight hours later I noticed my fuel pressure dropping rapidly on the right pump (dedicated to my right tank). It normally runs 45 psig constant - now it was dropping into low thirties and high twenties. Friday of last week I took it for a post-maintenance test flight and the pump would only provide 11 psi on runup.

I called BS and went back to the hangar and sure enough, the pump is cavitating - and temps were cool enough that the fuel is not going to be vaporizing from heat. I checked my fuel filters for blockage that could be causing the cavitation, and that's when I found one of them with the natural-rubber O-ring that was badly deteriorated. I remembered some discussion prior from Ross that said these pumps were quite allergic to cavitation and it would destroy the pump quickly, so I rigged up a test set and fed it clean fuel with no restriction on the inlet, and sure enough it would only give about 15 psig output - so the pump is nerfed.

Anyway - just a datapoint - cavitation (or air ingestion) is bad juju for these EFI pumps and natural rubber O-rings are only good for a couple hundred hours of exposure to 91E10. I'm in the process now of raping out the entire fuel system and installing an Andair full-duplex valve plus the SDS pump module and fuel regulator.

Empennage Ordered ...bkmerrill

Well, I made the jump and placed an order for an RV-10 Empennage Kit! No turning back now! Have spent the past several months going back and forth between building or buying a Bonanza. Finally decided I should quit wasting precious time and start the build. If I get the flying bug too bad a year or so from now, I may buy something to fly while I finish up the build. That said, I’m also very excited about building. Was at Oshkosh this year and love the community that we all get to enjoy through aviation. Look forward to several years of advice from you all. Will document our build at the (newly created) site in my sig below.

Well here it is.  The month of July: 158 hours building.   When the aft fuse first went on it's back: July 17th.  Total build time so far: 932.1 hours.   Rolling the canoe: August 5th.  A big thanks to my dad for spending many hours on the bucking bar.


Puppies in a RV8-It Can Be Done ...Mark Dickens

Several years ago, I was active in Pilots N Paws when I owned a Bonanza. It was a great plane to haul almost any size dog. In fact, I hauled so many aged and injured Pit Bulls, I took to calling my plane "the Pit Special"...ha. I sold the Bonanza and aside from a brief interlude with a Cirrus, I didn't have a plane to continue hauling animals and gave up on it temporarily.

I always found it very rewarding and always intended to do it again after I finished up the -8, but always wondered about how realistic it would be considering the space available. Seeing some of the recent stories reawakened those thoughts and I recently and unexpectedly had an opportunity to jump back into it right before Oshkosh. It's a story of two coincidences.

Out of the blue and with no action on my part, and for the first time in years, I was contacted by a rescue organization based in WI and asked if I could fly 8 puppies (later to be 4 puppies) from Magee, MS to my home airport Fayette County, TN. That was convenient! The pilot I would hand them off to happened to be someone I had met for the first time less than 24 hours prior to be contacted and whose hangar is less that 50 yards from my own. What are the odds? Sean would then fly them to Waupaca WI on his way to Oshkosh.

Needless to say, a RV-8 is not a freight hauling machine and I was concerned about the weight and the size of the crate with 4 puppies in it. The puppies averaged about 6 lbs each and the foster mom found a small crate for them. I removed the back seat and laid a moving blanket down to quieten things a little and it all fit fine.  ...

Central Australia Trip ...rgmwa

I recently flew my RV-12 from my home airfield near Perth in Western Australia, east along the coast into South Australia, and then up into the Northern Territory, finally coming back home through the`top end' of WA.

While it's hard to complete with Vlad when it comes to informative and entertaining trip write-ups, I thought the unique country down here might justify the attempt.

Still buzzing from finishing RV14, can't speak highly enough for the quality of the kit and plans, this aeroplane is good for GA, it gets a quality build on the ramp to a larger audience. I can see a big future for this model.


RV-8 Status Report ...j-red

I’m way behind on posting. July was pretty much a wash between work taking kids to camp and family vacation. This week I’m building the engine and will take a few photos for the records and share them, but here’s what happened in July...

More fiberglass! I’ve contjnued to spend inordinate amounts of time with the wheel pants. The gear leg fairings were assembled with their hinges and the transition fairings, which I bought from rvbits, we’re bonded to the wheel fairings, split, and a little overlap formed to cover the split. Lots of filling and sanding with no end in sight!

More sanding and shaping of the rear skirt joint and I’m finally pleased with that area too.

Carbon fiber wrapped the panel and got it installed. Everything works as expected. Radio checks on the ground seem to confirm good transmission and reception although we all know the real test is with the engine running....


Error Proofing and Organization...djborko11

I'm in the early stages of the build, absorbing as much as I can at this stage. So last week at Airventure I picked up this handy tip.

Put all the bagged parts with the same part number in a single container!
Dasani 12 oz water bottles make great containers for rivets!

I used my handy Dymo labeler to label the rivets for the water bottles and a fine point sharpie identifies the components compartment boxes ($2.99 HF)

My expectation is that I'm less likely to grab the wrong rivet or bolt this way.

My dream come true: Oshkosh 2018 ...Norcalrv7

As long as I've been in aviation, I've wanted to go to Oshkosh. In my eyes, the only way to go would require 2 things

1) Flying myself there from home in California
2) Camping at Oshkosh for the weekend

Time slipped by, and every year It seemed like the wrong time. When I met my girlfriend Tiffany 2 years ago, My hangar was home of an airplane with a completely bare firewall, and a gutted panel. She patiently watched me work, and I promised her that *someday* this airplane would fly me to my dreams to Oshkosh.

Sometime Around April, I decided that 2018 would be my year. I requested time off work, and plotted the route to fly. With only 170 Hours of time Lycoming FWF, The thought of a mid continent breakdown made me feel a little sick to my stomach. I guess the unknown is part of the adventure. I did know that my SDS EFI engine had run like a clock since day 1, So it should be the same a few times zones away right?  continue


#2 running hot and high oil temp ...RicoB

its's an 9A with a O-320 E3D / MT C/S electric prop, Just trying to get any tips on solution for hotter number 2, it's usually 15-20 degrees hotter than 1,3,4. others are around 385 and #2 is above 405, on a climb i see up to 425. I have already removed the front dam completely. also my oil temp is running about 210-215, my oil pressure is at 60psi at running temps, if i raise the oil pressure the oil temp goes up, if i lower the oil pressure down to 45 it runs around 185-190. Looking for ideas on how to attack this problem.. thanks

Behind the Panel Avionics Update ...AviatorJ RV-10

Wanted to show what I ended up with. There were a lot of decisions on the fly, some solutions worked through and then redone because I wasn't happy with the result.

The IBBS is above and behind the VPX. I can't mount the GSU on the G3X panel like I originally planned to so it's going to go on that brace to the left. I did put the ground on the right and the GEA 24 is on the subpanel where you can see those bolts.

RE: Weight in the RV-4 Back ...Brent Travis

I have 1100 hours in my -4 now, it weighs 975 (or so) with an O-360 and Catto prop. I did a couple of things to be able to haul a heavy passenger / (bags). First, I moved the battery into the engine compartment, in the right cheek. This allows a forward baggage compartment between the rudder pedals, so you can add weight forward of the CG. I usually put a bag of tools and heavy stuff like my O2 tank, oil, tie downs, etc up there.

Secondly, if I know I am aft CG, I always run the trim forward (down) so that I have more stick force and feel when I get slow with flaps down.

I like to land with half tanks or more if rear loaded.

I hope this helps.

A new RV Grin in Belfast Maine ...Dvalcik post

I am Posting this for Mike with his RV Grin.  Mike Giles and his RV12 took her maiden flight today. Today was perfect for a first flight, sunny, low temperatures and calm winds this morning. Mike made a few high speed taxi runs and then she took to the air just like all of the other Vans.  Mike’s PREP; everything was within normal range, no heavy wing, and flew level hands off.

He has 2 hours on the Hobbs as he as he continues the 5 hour phase one check list for the 12. Great to have another flying RV at KBST!  video


Home From OSH'18 Post ...Tony Kirk

I finally hit the pillow in my OWN bed at 2 AM this morning.  I left home on 7/11 for my daughter's wedding on 7/13 in Ohio.  Then flew Delta to the Atlanta area 7/18 to pick up N912VA from Vic and flew it to Oshkosh on 7/19.  Then I helped Roger and Big John prep the OWW booth Fri, Sat & Sun.  The real show started for us when the RV-12iS crates were opened at 8 AM Monday!  Many thanks to all the people who help push the OWW project to completion!   We wouldn't have been able to make the ambitious schedule without the help from the Van's community, both inside the ropes and all those who helped with the more than 2,500 volunteer riveters outside the ropes.  I also had the pleasure of helping "Rosie the Riveter" pull a rivet on Friday.

Watching Scott and Van taxi N2018 during the airshow on Sunday made me feel very proud to be part of the Van's Aircraft team.  I am privileged to work with some of the finest people I've ever known (including some whom you never see at Oshkosh), thank you Van and everyone at Van's Aircraft!

Thank you to the RV Owners at Oshkosh with open cowlings ...Trent

Just wanted to say, "Thank you" to all the RV owners that took their top cowling off and left it open.

Other than online I do not get many opportunities to see under the cowling of a RV. Since I am building it really helps to visualize some elements in person.

Obviously I understand why many do not take the cowling off. Heck they don't even remove the cowling on the RV's at Vans booth. So once again to those that are willing I really appreciate it. Thank you.

Vic's 'Home Safe' Post

Just landed a bit ago at home. Lots of storms to circumvent today. Have to love the Southeast in the summer!

What an honor it was for me last night to make the first flight of the Airventure One Week Wonder! It was an amazing culmination of a lot of hard work by the Van's team, along with some fantastic volunteers. I know some of the Van's team worked 20 hours days to make it happen, but it really did happen! A completely finished & flyable RV-12iS in ONE WEEK! I don't understand why takes us so long at home. The Van's team must have some special magic when they are all working together.

I don't know what was the actual final count of other people who came by to install a rivet and sign their name on the RV-12iS, but the last number I heard mentioned was over 2500. Isn't that amazing?!

What a superb accomplishment for the Home Built Community of EAA. I know many of you from this forum came by during the week to see it, and I really enjoyed meeting you or reconnecting with you!!!

Overall it sure was an amazing trip of which I never dreamed. I licensed an RV-7A in Madison, WI on the way up, and then test flew the RV-12 iS last night. That was fun.

Yes, I’m stupid but lucky ...Jim 7A

This year’s trip to AirVenture taught me a valuable lesson about C.G. and weight.

Like (I suspect) several RV owners I became complacent about cg and weight because these planes perform so well. Background: my RV7A is a little heavy to begin with due to a nice panel, oxygen system, lovely interior, pretty paint job and a few extra luxuries I consider important to always carry. In other words the basic empty weight is 1,188 lbs. My empty C.G. is 79.97 which is a good forward cg.

Last year I overloaded the aircraft by about 100 lbs. and had absolutely no problems. This year was different! I’ve personally gained 5 lbs., my passenger was a little lighter than last year’s passenger; so I put about 125 lbs in the cargo area and estimated my total gross weight around 1,950 lbs. Takeoff cg was within limits.

I was part of a two ship arriving Saturday night and when three minutes out of Ripon they closed Oshkosh ten minutes early. We diverted to Appleton. Landing at Appleton was stick sensitive but very controlled.

My lead flew to Oshkosh the next day (3.5 hour flight plus one fuel stop) while I elected to stay at Appleton since it was convenient and my parking fee for that Saturday night was the same as the whole week. I was also told OSH HBP was muddy so staying at Appleton just made sense. I had room reservations at Oshkosh dorms and took the bus to AirVenture.

Like a lot of folks I purchased a few things, picked up a few more “free goodies” and so did my passenger. Return trip on Friday added another 10 to 20 lbs aft. Our return trip had me stopping at North Central Regional (MO8) for fuel. Unfortunately they ran out of 100LL two planes before my turn (price $3.90 gallon). We still had 18.5 gallons so I flew on to Marshall Memorial (KMHL) an additional 20 minutes air born for fuel. This burned about four gallons more. Airplane felt unusually sensitive with a slightly nose high pitch on this flight.

My first landing at Marshall surprised me with severe PIO (never have I experienced this before) so I went around. My second attempt was even worse. Now I’m shook up! (I’m a 3,800 hour - long retired military instructor pilot - and PIO is something only rookies experience - right?). My passenger (a former Tora Tora pilot and Reno Air Racer calmly suggested I apply full nose down trim - which I did. Thankfully it worked and the third attempt resulted in no PIO and a safe landing.

Lessons learned:
1. Don’t become complacent. Play attention to cg limits and gross weight. While you can be within cg limits on take off, inflight fuel burn will move your cg aft. If already over weight this can get you into serious trouble if your cg at takeoff is near the aft limit.

2. Use FedEx or UPS if you suspect your overweight. Even better - don’t start overweight and expect to not have consequences. It’s cheaper to mail stuff than to damage the aircraft and possibly hurt someone.

3. If you find yourself trying to land your RV outside of aft cg limits - apply full nose down trim! It will keep your nose down and help prevent over controlling the aircraft as you try to make a landing. Remember an aft cg makes these aircraft extremely sensitive to control inputs. Full nose down trim dampens this out a little.

4. Make sure your lighter passenger deplanes first and have him/her hold the nose down while you’re getting out. Fat boys on the rear step will cause the tail to drop. We at least thought of this before deplaning.

I share this with you in the hope that you’ll pay more attention to cg and weight limits when you make a long trip. These airplanes are great little performers but they can make you complacent if you’re not careful. Remember “full nose down trim” can help reduce PIO when control forces feel too light.

Fuel Pump Trouble ...Jan RV-10

Standard RV10 and today I have connected the fuel pump for the first time. I can hear a faint clunk sound from it but nothing else on Pump On. Yes I know that it should not be run without fuel, but thought one or two seconds will do no harm. It trips the VPX even at 15A. Monitored it with the laptop and I am getting a Short Circuit message from VPX.

I have even tried an independent supply at 12V with the same result.

Wondering if it will help to push a bit of Avgas through it and then try again? Your advise is welcome - before I dive n there to get it out and halfway around the world

First Flight ...Wesflies

On July 6th, 2018, N1277G RV-7A changed from a 2800.3 hour (fourteen year, two month, and thirteen day) project into an airplane. It was a .8 hour flight without any issues. Flight handling was just as advertised and the landing was a greaser! I cannot wait to fly it again and get past Phase 1.

My RV is powered by a 180hp Lycoming Thunderbolt, and a Hartzell constant speed prop (Van’s show special at OSH 2017). The instrument panel was designed and built by Jared Solomon and me and includes two Dynon Skyview 10" HD Touch Screens, Dynon ADS-B in and out, Dynon Auto Pilot, Dynon Intercom and Com, and Vertical Power VP-X. The interior was done by Oregon Aero.

As you may imagine, after taking over fourteen years to build, there are simply too many people to thank. There were many people who helped in so many small ways. I’m sorry if I do not mention your name. However the folks that spent the most time helping and get special mention are; Art Sanders, Jere Rosser, Skip Elsworth, David Anderson, Scott Kilgore, and Jared Solomon. Jared gets honorable mention as he really helped me “get over the hump” the last eight months or so, and helped see this to completion. I can’t close this without thanking my wife, Joy. She was the most help of all! She NEVER questioned this dream and ALWAYS was encouraging when there was a bad building day. She never complained about how long it took to build, how much space I took in the basement; how much money I spent; I could go on. I am so excited to take her flying and to exciting places very soon.

Finished! ...Chad Boot RV-14

Dear VAF,

I unfortunately missed #OSH18 this year, but on the plus side I had time to finish my RV14.

It's done!!! I've finished I present to you RV14 VH-VNX built in Sydney Australia.

The kit finish and quality of the RV14 from Van's can be summed up by my AP's sign off "It looks like a factory built aeroplane" The aeroplane is fantastic to fly and an absolute credit to all at Van's.

A huge thank you to the VAF community, everyones support and experience sharing makes all the difference.

This aeroplane took me a solid 18 months to build, its a as per the plans slow build with the IO-390, dual P-Mags, VPX, Classic Aero Interior, fuel & brake lines by Tom Swearengen & TS Flightlines, and a Dynon fit out.

I can't wait to do it all again!!!!

VAF Hat Drama ...Mike

So, despite reaching out (I know you were busy JJ), I am in San Fran by myself on a layover.

I go into town, we stay in Burlingame, and I get to the end of the Hyde Powell cable car line. Half way back to Powell, my hat flies off.


Good and faithful hat of 10 years, recently repaired and well cherished.

Oh well - never mind. Cable car stops 2 blocks later and this guy runs up and gives me my hat back !

Way to go - Idaho

I gave him a good drink as thanks and have been re united with my hat.

2018 Home Safe From OSH Thread

- Back in Alabama (have work to do). Great trip home with a nice tailwind at 16.5K.  It was a good visit. I'm very lucky to have so many friends.


- Back in Arizona. Great trip. Refueled in Shenandoah Iowa and Las Vegas New Mexico. Both were quick, easy, and reasonably priced.
Lots of weather enroute but mostly smooth ride until the last miserable hour. Home was 115 degrees when we landed.


- In the air yesterday by 7:00 am, on the ground by 9:45...if only the flight up had been as easy!


- Great flight home Tuesday morning. Only 6.5 hrs. flight time vs 8.9 hrs on the way there Saturday and I didn't even do any laps around Rush Lake. Had a small tail wind vs the 20-40 kts headwind Saturday.
Typical TS in Florida but managed to stay East of them on the way down the peninsula.

RV IAC Aerobatic Competition Standings - 2018

Sorry for the delay in getting this out. I've been on a 3800 mile trip in the 4-wheel RV and just got back to my computer. We have three new entrants in the standings. Scott Emery and Dennis Parks both tried their luck at the Corvallis, Oregon contest and Galen Killam took a third place at the Michigan Open in Bay City. Lots of contests left to be flown this season, so get out there and post some scores!


So I took off the tape ...kentlik 7A rebirthing update

So I took off the tape and revealed a decent job but not even close to great. I didn't put "great" time into it and learning on the fly is kind of cool...most of the time.

  I had the 'One Week Wonder' project streaming on one of my monitors full screen all day Wednesday, and I couldn't stop smiling.  How dang cool is that thing?!?!  I'm pretty sure I saw Paul and Louise working on that sucker.  I wish there was a PTT button like on the Nest camera at the hangar.  Wanted to shout out, "Iron!!!!!" ;^)
  Hope my friends at OSH are having a great time.  The Wx looks nice.  

I can fly now!

Just received my Special Certificate of Airworthiness in the mail, so C-GCPT, RV-9A #91081 is officially an airplane. Weather permitting, my first flight will be happening when I get back from a short vacation, in 10 days or so. The plane is ready and itching to get into the air where it belongs.

I kind of wish we could get that instant gratification of the pink slip like you do in the US. I waited for nearly 6 weeks for my last piece of paper. I am delighted that I'll be able to start my 25 hour test phase while the days are still long though.

Rudder Ouch ...John RV-14A

It was bound to happen. I'm working on the empennage/Aft Fuselage kit and have completed the HS, Rudder, VS, trim tab and nearly done with the elevator. I keep the completed components on top of a cabinet in my workshop (garage). It has been over 100 degrees nearly everyday for the past couple of weeks so I leave the roll up garage door open at night about 6" to take advantage of cooler nighttime temps. Apparently, 6" is enough for a family of raccoons to come visiting.

The little blankity blanks, climbed up the cabinet and knocked the rudder off. It made quite the racket as it fell 6 feet onto the concrete floor. I rushed into the garage to see them staring back at me as if to say, "...wasn't us. The cat did it." Well, I don't have a cat so I know it was them.

My rudder didn't survive the short CFIT and there is no way to realistically repair it. Better to build another one. I called Van's and asked if they had a "Rudder Kit" and was told they don't. I would have to order each individual piece. I started going through the plans and writing them down but thought there must be a faster way. Maybe someone has decided to build a second rudder and they have a parts list composed??

7A Rebirthing Status Report ...kentlik

So I took the plunge today and feel pretty good the job is done. Kind of messy and not as clean as I would have liked but it is solid   You do need more clamps when you actually glue it up. I, fortunately, have dozens so just grabbed a bunch out of the bin.   Not sure when I pull the tape off. I need to let it cure then backfill and then I pull it off I believe is the procedure.  ...


RV-14 or RV-10? What were your arguments?

(Welcome Malte from Munich)
"Hey builders,

I am a bit afraid there are already twenty threads about this, but I couldn't really find them.
I'm thinking about building an RV myself. I'd like to build an IFR capable plane. I do not like to build lots of carbon stuff (have had enough of carbon building at university). And I like XC and some acro. The idea to visit different continents with my own plane is appealing.
Now I'm not sure whether to go with a ten or a fourteen.

What where your thoughts when deciding pro RV-14?



Pre-Flight Catch ...Tom

Before flying my "new to me" RV-8 back to Colorado last October, I discovered both locknuts on the throttle control cable housing at the carburetor bracket completely backed off..I'd actually flown it like this. I also discovered fuel spraying onto the ground during priming from an improperly made up copper tube fitting. During preflight runup before my first solo in my RV-8, the engine backfired badly when on the left mag. A local A&P, without actually testing it himself, simply told me to go fly it, saying it was probably a fouled plug (he probably thought I was having a case of "pre-solo nerves"). The 2nd A&P on the field I took it to tested it and declared the plane non-airworthy until the left mag was replaced. The 2nd A&P was top notch.

Recently, after having some mods done on my RV-8 down in AZ, I found an abnormally high amount of friction when moving the ailerons during preflight. The aileron had been removed to perform an inspection and reassembled improperly. After takeoff I noticed a heaviness in the left wing that wasn't there before....later traced to the trailing edge of the right flap being about 0.1250"-0.1875" lower than the left flap when fully retracted. My transponder was also not working. Would be nice if the workshop performed their own preflight inspection before I got there.

There's nothing like having work done by paid professionals only to have it come back with squawks that were not broken before, costing extra money to fix. I'm learning that part of the ownership learning curve is finding a reliable shop/A&P to work on the plane. I've been throwing money at it for the past several months and believe the "deferred maintenance items" have now been addressed.

As a result of the above...and spending a lot of time scouring VAF, I now take more care than ever during my preflight inspections and now have a better idea what to look for.



July 25, 2018.   Issue #4,617.
  My hometown of Waco, TX was 114°F a couple days ago (link), and two hours north by car where I live now it has been a true cooker (screengrab), so I've been gravitating to the worn out shared Cub with its open doors and shade when the heat gets too much.  Tuesday a.m. did TnGs on a dried up lake bed (pic/pic).
  Don't take it personally, my darling RV!  I'm trying to avoid heat stroke here!  The gang at OSH sending me 'how cold it is' updates isn't helping much <g>.
  And yes, I've been researching air conditioning units for the RV-6.  We'll figure out something.

Behind the panel avionics placement ...AviatorJ RV-10

I need some mounting or arrangement suggestion, ie mounting locations and/or brackets I can make. So far I have only had to cut a single hole into my subpanel for my GTN 650. Decided to jump on in and go ahead and get those trays and the wiring harness into the plane.

So here's what I have shown in the picture with a bit of painters tape holding everything in an approximate place I think would accommodate space and with my Stein harness.  ...


Round the World in a RV-9A ...John's update


Tomorrow I depart for Pago Pago and will prepare for the upcoming long legs. The plane holds up to 124 gallons of fuel, but even with this capacity I will need to fly fairly slowly to ensure the range.

I had hoped to be in Oshkosh by this time. Weather delays in the far north and illness in India slowed down my progress.

OSH Arrival PIREP ...Scott Thompson

I was this poor RV-8 guy. Very frustrating arrival experience that began Saturday afternoon when they closed the airport for arrivals at 6:30 instead of 8:00 to allow 140 Bonanzas to arrive. I was 10 miles from Ripon when that happened and had to divert to Appleton. Today started off well enough. When the weather went to marginal VFR at about 11:30 I launched with others from Appleton and I almost got right in. Shut off arrivals just as I was in line at Ripon again and went to holding. It then became a real zoo on the Fisk arrival with guys not following the NOTAM and cutting people out of the flow. It became a game of chicken in some cases; who was going to turn out and give up first. I know the ATC guys were working hard but I was not impressed. Five guys converging ar Ripon and no one turning until someone had to. ATC would tell everyone to break off and hold, and 80% did so. The ones that pressed on were then getting in. I tried for over five hours to get in and had to refuel again at Appleton. The guys who declared minimum fuel to ATC were given priority instead of being told to divert. Finally made it in just before the field closed again for the day. Weather was great this afternoon but what a circus. Not sure I’ll do it again. I‘ve flown in a couple of times before and never seen it like today.


OSH Arrival PIREP ...Gary Sobek RV-6

After holding for more than an hour 5-miles south of RIPON, I diverted to KUNU Dodge County and took an UBER to OSH.

I did not like what I was seeing on Stratus Foreflight ADS-B traffic in.  ...


OSH Arrival PIREP (Ground) ...Turner Billingsley RV-14A

Due to a number of other destinations on our trip we drove to OSH this year. On the drive up today we spent time at Ripon, Fisk, and watching arrivals to RWY 9. We arrived at Ripon about 1-2 hours after weather went from IFR to "marginal VFR" and was pretty much VFR with rapidly improving conditions.

From the ground, Ripon looked like an absolute madhouse. Airplanes coming from every direction, breaking into the "conga line" from both sides, speeds varying, etc etc. Lots of "last second" break-offs. At one point EVERY aircraft turned left - clearly instructed to do so by controllers at Fisk.

At Fisk, listening and watching, the madness was even more impressive - controllers were asking for "1 mile" spacing and it looked to me like "1/4 mile" spacing at best. Probably 70% of aircraft arriving at/approach Fisk were turned back to rejoin the line - this didn't seem to be helping as more aircraft were clearly arriving at Ripon by the minute. Even at Fisk, the adherence to flying "over the tracks" was amazingly inconsistent. I was also surprised how many singles, including RV's, were flying the "high route" given the performance capabilities, but they weren't getting any special treatment.

Watching arrivals at RWY 9 things were much better, although I saw several very closely spaced arrivals with "go around" instructions - in one case a Malibu was flying higher and faster than another aircraft on final and I don't think the pilot had any clue there was another aircraft below/ahead.

Quite a spectacle and a good learning experience in how to prepare when I fly to OSH.

Baptized the gas tanks but...prostate problems ...Kurt Haller 9A

OK, so another big day...first gas.

Got 20 gal of 100LL in four 5-gal jerry cans. Took a bit to figure out how to transfer gas 2 gal at a time (into a couple 2 gal cans) to calibrate the left tank. Newfangled spring-loaded safety spouts have to pushed back by a tab bearing on the lip of the container or filler neck of the fillee. I put 2 gal cans against the outside of the hangar door, fill neck face out, keeping them from moving when the 5 gal jerry can bore down on the lip. Thirty pounds of gas is heavy!   ...


What should I always have in my RV?

As I continue to get to know my RV7 and start to venture outside my loca area I would like some input of what I should carry in my RV at all times.

I am putting a small bag together to always have in the aircraft.
Obviously I need a quart of oil, screwdriver to open oil door..

My tie down rings? My anti splat control lock? Etc.

What tie downs do you recommend?

What collectively are some best practices?

1 Week Wonder Webcam Link

(Greg Hughes)  We will be having the one week wonder web cam live at EAA starting on Sunday eveing. The work and ceremony (open the crates etc) starts Monday morning at 8am central time.  .....It will be up all week until the work is finished."

Ready, Set, OSH! ...scard

Annual 'made it safe to Osh' thread. ...[ed. ...and where I am parked. dr]

Well Shantel, the airplane, and I made it safe to Osh at 5pm. 1 fuel stop and 1 field closed due to IFR conditions which resulted in another fuel stop and wait along with about 75 of my closest friends at C47 and once the field went VFR, we blasted this way. Let’s just say the arrival was not flown at 1800’!

I ran all the way from the back row of HBC to the GES shack to get our box we shipped up here (54lbs).... lucky for me they were still open! Lesson learned, don’t put your tent in the box!

We are in row 313 by the cell towers right next to Dan Horton.

Air Show Practice

Here is practice flight of some of the RVs that you will see in the Thursday Air Show.

I forgot stuff. Can you fly it down maybe?


The Thursday Arrival.... Ironflight

All that practice - 90knots (+/- 1), 1800 feet, dead over the tracks, be ready for anything....and today I needed none of it! For a variety of reasons, I like to make it to the show early so that I can have a relaxing day just sitting chatting with friends in the Homebuilt world. Usually, I try to make that a Friday arrival, but the weather today was gorgeous across the country, all the way to Iowa - and the forecast for Friday is iffy - so I found a safe way around the afternoon storms and came all the way in, arriving about 1800 local.

I fly in to Oshkosh occasionally for business when Airventure isn’t going on, and it is a pretty sleepy little towered field. Today it was just plane fun - the regular controllers were running the show, and welcoming everyone showing up early. If you sounded like you knew where you were going on the field, they pretty much gave your taxi instructions as “cleared as requested”. I think they all go on leave tomorrow at sun up, so they were having as much fun as we were.

I was cleared for landing from a two mile right base to 18, and when I asked if he needed me south of 9-27, he said “there’s no traffic there right now, make it long our tight, your option!” Like I said...Fun!

See you here!


Canopy cut!!

Well another 9 gets it's big cut. Took advantage of the beautiful 85 degree day here in WNY and decided to quit thinking about it and just do it. It was also a small goal of mine to get it done before we leave for Oshkosh Sunday. Need to order the Sika flex now!

Scored Cylinders

Well, timing is not optimal. I scoped the cylinders after compression check today and found some vertical scoring in the cylinder walls on #1 and #3 with 600 hrs since new. Compression is 74/80 on both and oil consumption has been about 1qt/8-10 hours. I'm wondering about a bad ring that's moving around a bit. I have some carbon build up on pistons, any possibility it's just carbon getting caught by the wall? Thoughts?

Disagreement on numbers in brake cylinder ...Bob -12

On the RV-12iS instructions, chapter 28, page 2 figure 4, the call-out for WD1211-L&R show different orientations of the Tabs on the drawing that what the actual part shows.

It would appear that either the ID of the drawings are reversed, or the labels on the parts are.

But I need this confirmed before doing anything further (rats!)

Oshkosh Family Reunion Arrival ...Capt Sandy

Arriving at OSH this year truly felt like a family reunion. Dan Horton says it well: "When we first come to OSH , we come to see the planes and the airshows and forums. After a bit, we don't care about any of that stuff. We come to see our friends." SO TRUE, Dan. Here are a few photos:

Round the World in -9A Update

Good Ground Shot

Status Report ...jcarne

After finishing the gear leg mount holes it was time to install the various angles for the forward fuselage.

After the F-713 auxilary longerons were installed it was on to the F-719 stiffeners. The F-719 angles took quite some time as the clips can have an edge distance problem if your not careful making them.

David Paule -3B Status Report


Before I can glue the forward side skins on, the tunnels have to go on, at least where they fit in between the side skin and the lower longeron. Since I did a poor job on the left one, it’s on order and I’m working on the right one.

Both the forward tunnel bulkheads are riveted to the belly skin.

I’d planned to install the Fiberfrax and titanium underlay (overlay?) at a later stage in the assembly, but a trial fit proved that the titanium would not go under the tunnel inboard flanges then. I need to install the titanium before the tunnels go in. This meant that today’s job was fitting the Fiberfrax and locating it.

I trimmed it to size, adjust a little to suit, and then pressed it into the spacers along the belly skin. Here the Fiberfrax is cut out for the first one. The Fiberfrax is so soft that it’s easy to do this just by feel.

Favorite Picture of N164BL So Far...

This was a frame grab from a video taken by a friend. The interesting thing about this was that just a few moments earlier, we were lined up on the end of the runway staring down a coyote who seemed sure that he had more right to be on the runway than we did. He got bored and left, which enabled our two-ship to get the day started.

Another RV-14 Airborne ...Jeffrey Jones first post.

While this is my first post on VAF I have spent countless hours - as we all do - reading, learning, pondering and hoping to some day see our aircraft fly. Thanks to all of you who take the time to pass on your experience. And a huge thank you to the Reeves family to making VAF available to us all.

I have the utmost respect for those of you who have completed builds in a garage, workshop, living room or wherever works. Congrats to all of you. I live in Hawaii and having an airplane here is pretty much futile due to inhospitable airport managers, crazy winds and salty air. So my airplane will stay in what we call “The Mainland.” It didn’t make sense to build in the corrosive environment in which I live, only to have to pay big bucks to ship it East. For that reason I decided to build my aircraft at Synergy Air in Eugene Oregon. Their hangar, their tools and their expertise made my build much less gut wrenching than it may have been for many of you at-home builders. Again, kudos to you all!

Since embarking on this journey I have had nothing but pleasant experiences with all the vendors that help make completion of our project possible and I thank all of them for their professionalism and dedication towards us.

Garmin GTN 6XX/7XX Descent Vertical Navigation,

Garmin G5 and G3X Touch systems have always had coupled VFR VNAV capability to use the autopilot to perform functions such as descend from cruise altitude to pattern altitude, but up until now, we have not had the ability to use coupled VNAV when using the GTN navigator.

With GTN V6.50, pilots can take advantage of VNAV profiles throughout the enroute and terminal phases of flight within the GTN 6XX/7XX touchscreen navigators when they’re paired with the G5 or G3X Touch system. Within the GTN, pilots can easily enter altitude constraints on the flight plan page to set-up a vertical descent profile. Pilots also experience a near-seamless transition from VNAV to an arrival and instrument approach. Once an arrival or approach is loaded and activated, the GTN automatically populates step-down altitudes or any applicable altitude restrictions. If ATC issues an unpublished altitude restriction, pilots can enter those altitudes manually into the active flight plan under the VNAV field.

Garmin Transponder Software Updates at Oshkosh 2018


We will once again provide free software upgrades for Garmin Mode S transponders (and the GTX 327) used in Experimental aircraft at Oshkosh.

Just bring your GTX 327, 23ES/33ES/330/330ES, 35R/45R/335/335R/345/345R transponder in to us at the Garmin tent at Oshkosh and we will install the latest software into your transponder while you wait. It only takes a few minutes to accomplish this update.

Here are the latest versions:
GTX 23ES/33ES/330/330ES: V8.04, Jan 2018

GTX 35R/45R/335/335R/345/345R: V2.12, June 2018

GTX 327:
GTX 327 V2.10 software was released in Feb. 2014 and is the latest software for all GTX 327 units manufactured before July 2014.

GTX 327 V2.12 software was released in July 2014 to support newer hardware in the GTX 327 units manufactured after that date.

GTX 327 V2.13 software was released in Aug. 2017 to address an altitude reporting issue only when using a Gillham based altitude encoder with GTX 327 (011-00490-00) serial numbers 83750922 to 83752847 or GTX 327 (011-00490-10) serial numbers 84000356 to 84000357.

We are located across from the EAA Welcome Center and the Ford tent. If you look at the Airventure grounds map, this is grid K13. From homebuilt camping, just follow Knapp street South to Celebration Way (the main entry street) and turn left.

Sorry, but we are not equipped to perform sign-offs for certified aircraft, so please only bring us transponders that are installed in experimental aircraft.

Hope to see you at Oshkosh!"



July 19, 2018.   Issue #4,613.
  Wednesday morning around 0800 I flew the RV for .3hrs, just long enough to scoot over to the lake and get some pics of the Saharan Dust event currently covering our neck of the woods.  A sample below...  The more interesting part for me was turning back to the field, flying away from the sun.  I heard Kay call his takeoff at 52F, then saw a white dot climb up over a tiny field of green trees.  Glancing down at the GPS showed me 5.1n.m. from the field (just shy of 6 statute miles).  That the viz should be so crummy 180* the other way was an interesting paradox.
  As I type this it's 106*F outside (5pm Wed).  Summer says hey. ;^)

Change to higher pressure rating aux. fuel pump

Van’s Aircraft has published RV-12 Change Notification 18-07-12, which describes the optional remediation of potential low fuel pressure warnings which can affect some Rotax 912 ULS equipped aircraft. Note that field experience shows that not all aircraft are affected, and the information in the notification may be used to assess your specific situation. If you have experienced low fuel pressure warnings, we recommend you review the change notification and use that information to assess your aircraft.

The remediation steps described in the notification include determination of which sensor unit is installed and new EFIS settings, as well as the optional installation of a different model electric fuel pump, which is identical in size and can be installed in the same location and using the same fittings as the original model pump. The new model pump provides higher fuel pressure capability.

Note that a supply of the new pumps is on order and Van’s anticipates delivery to our factory within a few weeks. Van’s Aircraft’s part number for this pump is ES 40135, and the Facet part number is 40135. Quantity one (1) Van’s part number ES 421-0107 CONNECTOR is also required. In addition, Van’s support staff is currently working at the EAA Airventure show in Oshkosh, Wisconsin so replies to support requests related to this optional notification will be delayed.



"...Huge announcement here…..after years of R&D, testing, and the submittal process to the FAA, we are imminently close to having the very first ever 12V TSOA certified battery available for sale by fourth quarter of this year! (TSOA means the approval that authorizes a manufacturer to produce a material, part or appliances to a TSO standard. Receiving a TSO authorization is both design and production approval). "

Fuel line vs. Flaperon mixture arm ...Bob Collins

Apparently, there is a missing step in the RV-12iS instructions. You have to countersink or enlarge the holes on the three plastic "holders" for the fuel lines through the main channel. Otherwise you get this.

Pulling those lines out to be able to get the plastic doohickeys off the large "studs" is going to make my day. But that's the way it goes.

Even if I do that, however, that looks like a REAAAALLLLLLY small clearance between the filter bypass line and the flaperon mixture arm.

Is there anything else I'm missing here?

  The Sahara Dust is back in DFW (search it).  Turning crosswind Tue a.m. into a rising Sun around 0800 had me (and other locals) commenting on the radio, and wondering in the back of our minds if flying was such a good idea.  Reminded me of those sunset on Mars pictures.  Reminded Sid of his time in Saudi Arabia.  Weird stuff for Big D. 


Ready for Her Close Up ...Krea Ellis RV-7A

We are beyond thrilled with the execution of the design our son (a twenty something) and Jonathan came up with for the RV-7A. To be honest, I wasn't sure I would like the design, but it wasn't as far out in left field as I thought. The more I was around it putting it back together, the more I loved it.

The attention to detail and the little touches that Jonathan and his team added are incredible.

I know it's not for everyone and that's a good thing!


Trailing Edge Bend Update ...Trent Stewart RV-14 (Australia)

Thanks for everyone’s help. I think that worked pretty well.  After final drilling one cleco at a time to #40 the holes on the bottom look nice and round. There is maybe 1/64th of pillowing in a couple of places on the left skin but this should be held down by the tape. Phew.


Gallagher is Coming to OSH ...VAF advertiser

Before we get into the who's where segment of this post, we wanted to start by thanking everyone for their support. The three of us would not be as successful as we are if it weren’t for you. We wanted to let you all know how much we appreciate each and every one of you. Vans are our top priority. We consider ourselves specialists in this field because we insure around 2000 RVs and this is the majority of what we handle day after day.

Quirky Things Seen From the Air ...Vlad entry

Somewhere in Saskatchewan CA.


Don't fix it if it ain't broken, well... (daddyman RV-4)

My lights were working just fine.

This breaks one of my big airplane rules- DO NOT FIX IF IT ISN'T BROKEN.

In this case, I couldn't help myself because;
I was hesitant to use my lights near the landing pattern, or in other conditions that could have increased visibility and safety because the previous owner said the electrical system "couldn't keep up with the load". Still not sure if that was the case. Since all things electrical are mysterious to me as Merlyn the Magician, I accepted his words.

So, I took the old lights (landing and taxi) out and replaced them with LED lights.
I had previously changed the landing light bulb for a "higher intensity" one, but couldn't tell the difference when landing at night.

Fast forward to this upgrade.
The following are pictures are from my son and student pilot (read Guy in back) -Buddy.

AEX Trailing Edge Bend Tool ...Trent Stewart RV-14 (Australia)

I had considered the skins - however if i screw up a skin then the cost to send a new one to Australia would be astronomical. The AEX wedge wouldn't be so bad... Plus the thickness of the wedge seems to work really well with the brass tube tool i made to align the drill. It fits a 1/16" drill perfectly into the centre of the tube, and the tube fits snugly in the 3/32" hole already in the wedge. Once it's centre drilled (and at the correct angle too), i then updrill to 3/32" to match the hole in the AEX wedge. Seemed to work ok on the practice piece i did - the holes in the wedge were not enlarged. I will then cleco the tube to the rudder and match drill the whole lot to #40.

i realised that the alu tube i purchased will prevent me from squeezing the rivets, so i'm going to get an angle instead today and match drill that.

I am still working up the courage to have a go at the trailing edge in the next day or so - i think if i start in the centre and clamp / cleco the wedge keeping it aligned with the straight edge of the angle i should be ok?

9A Cowl Plans Revision - Did the Cowls Change? ...Dave Gribble

I have a pink cowl shipped in 2010. I recently got a updated version of the preview plans on USB.

I notice that R2 of DWG 45 (in 2008) deleted Section A-A, and the trimming notes, shown in red below on an R1 version of the drawing.

The old plans have the trim notes, which say to remove the flange completely along the sides... so the top and bottom cowl essentially touch, but don't overlap.

My question is, did the cowl design change at some point, or is trimming this flange off a bad idea and Vans just updated the drawings. I don't see any changes in the instructions, but they are pretty high level anyway.

I'd ask Vans but I have a question into email for a week already and thought you all might know. I'm planning on quarter turn fasteners on the sides but don't think that matters.

Thanks for any info!


New RV Owner Chimes In ...ALagonia

First I looked to buy a 6A, then a 7A and then a 6A again. I had Vic helping me, and I highly recommend Vic Syracuse. He not only did very thorough pre buy inspections for me but I learned an awful lot from him in the process. And that was very important for me because while I have owned numerous airplanes over the last 41 years this would be my first home built experimental. Thank you Vic. Well I am happy to say I finally found the airplane that was right for me, an RV9. Stein, of Stein Air, is completing an inspection for me and I can't say enough good things about him. Truly a quality guy. Thank you very much Stein. I go next weekend to finally get my airplane. Will fly it back to Georgia next Monday, weather permitting. Ready for my RV Grin.

RV-8 N657AR Update: Goatflieg

After getting the rigging of all control surfaces squared away it was time for the final major disassembly. I removed the empennage components, flaps and ailerons and got the wings ready for removal. With assistance supplied by Joe Kirik, Bruce Breisch, Dave Buck and Joe Fredericks I was able to get the wings removed, placed in the wing stand and stowed in the garage. Then we flipped the fuselage onto work stands so that I can install the landing gear permanently. I'm very tempted to paint the fuselage bottom while it's in this position... we'll see. Thanks to my crew for making quick work of some tricky tasks.


Tom Swearengen: TS Flightlines Update

All----As some of you are now aware, I've been absent from posting alot on VAF. Not that I'm mad at anyone, or have been MIA. Yes, I've been working, but I do want to explain briefly.

In January, Suzanne was diagnosed with breast cancer. One of those out of the blue, laser GPS guided missiles that you never see coming. All of her previous mammograms have been negative, so the shock and awe of the reality was alot to take.

She had successful surgery in early February to remove the lumps, 11 lymph nodes, and biopsy the tissue. It came back malignant, stage 2. Ok, treat it, an lets move forward. Just before she was to start chemo, we asked the DRs if there was anything else we needed to be concerned with. We asked, because she was having some difficulty walking, and CERTAINLY these were 2 unrelated circumstances. But we wanted to know, so we had them do a CT scan, and a bone scan.

2nd missile---The CT scan was negative--more on that in a second, the bone scan showed excessive cancer 'spots' in several ribs, her right pelvis, lower lumbar, and upper arms on both sides. Boom.

After digesting this--and seeing the stunned, pale, drained look on several DR's faces, we asked for a bone biopsy to see if the 2 cancers were related, or if we were dealing with a HUGE issue, not that MBC breast cancer isnt huge enough. The Biopsy showed it was the same cell makeup, so at least we had identified the enemy, and now had a plan. The CT scan was very puzzling. We insisted on a PET scan to see exactly what and where we were dealing with. It showed the cancer had spread to areas not shown on the CT scans.

Radiation was started to zap the spots to at least slow them down. 8 treatments. WE got another CT scan to see if the radiation had done any good, and the results were-cautiously optimistic. So a chemo regiment was started---12 weeks worth. Grueling. Some nausea, but not bad, but the pain of moving around--even sleeping and trying to roll over, well I'll just say that no one slept.

By chance, a couple of trips to the ER because of fear of either a broken rib, or a blood clot allowed us to get some additional CT scans. Imagine that. AND by a stroke of luck, we were able to get the same Radiologist to read the scans. Things improving.

Friday, Suzanne has a CT scan and a MRI. So much for bad luck on Friday the 13th. MRI of the head shows NO cancer. CT Scan shows no NEW activity, and healing of the bone areas. So---we think that she may have turned the corner on this enemy.

So--how is all of this RV related? HUM---even though my online presence on VAF has been limited, we have continued to talk to clients and support them in their build projects. In addition, we've done some 'interesting' projects for some custom installations. A HUGE help has been from Steve Tschurwald, my partner at Aircraft Specialty, with who we've developed quite a few packages for RV's and others. Steve has be gracious enough to handle quite a few orders for us, when we had orders to do and no physical means of doing them. Same components, same quality, shipped from a different location.

Some of you that we've talked to on the phone or by email were aware of the situation. Out of respect for Suzanne, I didnt post anything, but she did give her permission to post this. So, I'm explaining whats going on, and assure all of you that we are stronger because of the challenge.
Its also given us some time to evaluate things and how to make them better to help all of you. You'll see some of those changes being implemented.

For those of you that knew what was happening, your thoughts and prayers were greatly appreciated and certainly helped. To our DR friends that listened and gave sound advise---it means alot to us to know we can call and ask questions! Yes VAF is an unbelievable resource!

Suzanne will not be at OSH this year---way to soon for her to travel and she is on the downside of her chemo treatments. But I'll be there and hope to see alot of our friends and clients enjoying the great event.

The Hammer of God

(from Terry Kohler, who asked me to share it here as I'm hosting the photo for him)
This screen shot from Flightaware was taken on our recent trip from PTK to CMX on Michigan’s UP. You can see the outline of the Keweenaw Peninsula in front of N323TP as we make our way northwest. We were tracking the weather visually as well as on ADSB. We landed and hangared in VFR about 30 minutes before it hit. Our “out” was a 180 back to Marquette in clear skies.
As we were flying in, Peggy asked if I considered this a big storm. I told her it was “the hammer of God”. Later, sitting safely in a café in Laurium, the winds, rain, and hail confirmed my description.
Fly safe (and ALWAYS leave yourself an out).


Symptoms of a cracked head on take off

Engine miss and maybe dropped couple hundred RPM and Intermittent as well on 2 trips back to back a few hundred feet off the runway on takeoff. I had time to kick the boost pump back in, apply carb heat and play with the mags. Maybe 10 to 15 secs and then it would go away. The first time I thought maybe carb ice, maybe fuel pump getting weak or **** in my fine wire plugs. Then the trip home it happened again but not as strong but the harmonics in level flight were off slightly. No one else would notice it but with it being my only ride I could certainly feel something not quite right. I had a suspect cyl (#3) in mind as 15 hrs ago it tested 72/80, as I could hear it bypassing, it was not through the exhaust nor the intake. Sounded like the crank case so I was thinking rings and even used my stethoscope to confirm it so not overly concerned.  ...

Rough running engine at 100’

Happened a week back and I am out of town so I don’t have all the details...

Rv7a. O-360 engine, bendex mags, 800 hours ttl time. Never an issue.

Jumped in to fly and for the first time ever the engine was very hard to start. It would crank and back fire every once in a while but never really fire. Went through flooding the engine and all those techniques. Finally got it going. On the run up the left mag was very rough. Leaned it out and it cleared up. Good to go. At about 100’ the engine started backfiring and sputtering. Pulled it to idle and landed no problem. Taxied off and did the run up again. Left mag number one cylinder was significantly cooler get than the rest. Pull the plugs and the bottom plug was completely loaded with lead. Cleaned it out and put it back together.  ...

Have you ever caught a problem during preflight? ...walter's entry

(Walter Tondu)
In the 90's I got a lead on a Cessna Hawk XP II up in Michigan that was for sale; low hours and in great condition. It would be my first airplane purchase so I was pretty excited. I coordinated with a reputable on-field A&P shop to do a pre-purchase which went fine; several squawks were noted and fixed. I received a report that the airplane flew very well! I flew up commercially, hot check in hand. The airplane had been stored outside during the Michigan winter but was now inside a nice warm executive hangar for my inspection. Prior to moving it outside for my inaugural flight I did my newly-minted-pilot walk-around with Cessna checklist in hand. Eventually I sumped the tanks but the liquid was clear and did not smell much like fuel. That's strange I thought. The mechanic had a look and we both agreed, that is strange. Sumped again, and again, and again, and again. Nothing but clear water. The quick drains were removed and over a gallon of water was removed from each tank. That's what we caught in the bucket, the rest on the floor. The wing tank bladders were both replaced at some cost to the owner and I purchased it and flew it home. During the VFR flight home the AI and VSI went TU.

1st note to self: Remember, ice has a hard time getting through a quick drain.
2nd note to self: Reputable A&P shops are not always.

Canopy track lube?

What, if anything, do you use to lube the canopy track on your 8?

A: Nothing.  We take the wheels off from time to time and use some molly on the shaft. Other than that we keep the track clean by wiping it out with a cloth. The roller wheels will need replacing as they wear down over time along with the rear slide block. All of this is just a visual inspection and on the PM list of things to check. Just what we have found over time. Yours, R.E.A. III # 80888

Like Robert I just lube the roller shafts with a light oil occasionally. Biggest thing to me is keeping the dirt out of the track. Larger particles tend to chalk the wheels.
The rear slide usually causes the greatest resistance. A little synergism from other experiences comes to play here. Some years ago a tech rep for vinyl windows on my home recommended Lemon Pledge to clean and lube the sash tracks. Worked great. Many use the same product to clean plexiglas. So after cleaning the canopy I dampen the cloth with Pledge and wipe the track on the turtle deck. Once out of the latch well the canopy will slide on its own.

FWIW, I occasionally spray some SailKote on the track. I used it in the track of our main mast to help the delrin slugs travel more smoothly through the track in an aluminum mast.

As I note on my ship - the spine track gets sticky or scuffed or just angry with our treatment of it on some odd timeline. I polish the upper sfc with Rolite and it's good to go for a while. Lots of buffing makes no difference in how long the job lasts.  I'm trying to think of how long a 'treatment' lasts - maybe 90 days or so? I notice the change when I turn around & taxi back - does the canopy thunk into the stop (also on the track - FYI - don't ask the trucks to absorb that shock load for any extended period of time especially on the T/D ships) or does it need some particular words to be uttered?  I clean the tracks yearly at the condition inspection.


Cutting and Buffing Paint Saga Update ...snopercod

The saga continues. In our last episode, I had re-sanded the top of the fuselage with 2500 and 3000 to remove the heavy swirls from the 3M Perfect-It #1 compound and the DA. I had started buffing with the rotary buffer and the #2 compound, and it was looking OK...at first. Yesterday I finished buffing with the #2 and went to the #3 Ultra-Fine, which is supposed to remove swirls. It didn't. All it did was make the fuselage top real shiny but, sadly, it disclosed several areas with scratches from previous hand sanding and other areas that were scuffed looking. Undaunted, I dropped back and re-sanded those areas with 2500 and 3000 grit, and re-buffed with #2 then #3. There were still some scratches and scuff marks showing so I did it all again. After the third time I just threw up my tired hands and said, "That's good enough!".

While stuck in Groudhog Day, I started re-thinking my decision to bypass the #1 compound. Maybe that would have taken out those defects before going to the #2. Maybe the DA was the problem, not the #1 compound. I guess I could run a test using the #1 compound with my rotary buffer. Someday I may do that. That's the great thing about cutting and buffing: You can always come back years later and work on it some more...at least until you run out of paint

Here's the back side of the buffing pad I was using on the #3 compound. I thought it worked well - the beveled front face made it easy to hold the buffer at a slight angle like DanH recommended. I used a yellow pad for the #2 and a black (softer) pad for the #3 - both from Harbor Freight. After use, I am storing them in gallon baggies so as not to become contaminated.

Ads-b Peformance Report Fail--- Please Help Me! ...Darren Kerns

I just had an uAvionix Echo installed in my RV7.

It passed the Compliance Report on the ground at Ron Collins.

However, tonight while doing the performance report in EVV airspace I got a 100% fail in Barometric pressure and Mode 3/A.

I have talked over and over to AFS and uAvionix about configuring everything. The Echo is wired into serial port #3 on the 3400S efis. I have had to configure everything because Collins did not do any of this. Well, some stuff they did but a lot they did not.

I am calling AFS and uAvionix tomorrow and I plan on flying the 7 back down to Collins to see if they can help.

Traffic and weather is showing up great on my iPad Mini 4. I have had other planes say they are picking me up good on their screens

I am wondering if I have something set wrong in the uAvionix Echo configuration page. Kurt at uAvionix can help me with that.

Shawn at AFS & Kurt have been great. I just don't know what else to do.

Can anyone tell me what I am missing? I am about to pull my hair out!!

  Work continues on our 80's era broken sprinkler system.  Latest update is a video showing a comically large amount of leakage directly under a Bradford Pear tree in our backyard (pic).  It's taken three evenings to get to this point with an axe and shovels (clay soil and root balls from Hades).  Growing Popeye arms.  It's time for that expletive tree to die, so now I'm wondering who I loaned my chain saw to.  I wish I was joking <g>.  And it wouldn't bother me if it fell on the deck 'by accident' - would prefer more grass.
  I'm gonna whoop this thing if it takes the rest of my life - so far it's a little too much like an episode of the Three Stooges.  You know the one.

On a post-maintenance RV-8 flight a week ago, friend/A&P Monkey at my field took a face full of dried Mud dobber nest out of the vent right at rotation.  The plane had extensive panel work done and had been down for at least a month.  Randy said at VR a half-golf ball sized clump of dried dirt came out of a vent and whanged him right in the puss.  Kinda thing that can distract a guy...

Dirt in rear passenger foot well,
after breaking up on Monk's kisser.

From a safety standpoint, I guess the takeaway from this is the idea to maybe seal off the vents during long term maintenance or maybe direct the vents downward on that first post-work flight.  Or at least wear sunglasses.

Plastic eyeball fresh air vents ...bmarvel

With nearly 2000 flying hours in Van's aircraft I have built, I admit to being a big advocate of the company. But now and then I take exception to something and the plastic eyeball vents in the -14A are one of them.

These seem to have worked OK in our RV-8A in So. Cal. with the mild climate. Yes, they leaked air but that was a relatively minor irritant. But here in Colorado those same vents in our -14A ultimately caused me to replace them. They not only leaked air readily because of poor sealing doors with a loose on/off thumb control but also failed to maintain direction. Numerous times one vent or the other ended up moving on its own and shooting air into my or my wife's face and microphone, breaking squelch. It was OK for awhile but we finally opted to remove them and go with Van's more expensive but much better aluminum eyeballs of the same size. They hold direction and seal much better and have the usual twist method for on and off rather than a thumb control.

But not so fast. Because the plastic vents are mounted between two components that are siliconed to the fuselage, you can't just replace the vents. You have to remove and then replace the whole assembly -- NACA duct, eyeball and mounting bracket. While this was not difficult to do with a sharpened putty knife slowly slicing through the silicone, it was both time consuming to get down to bare metal and awkward working under the panel. I bought all new parts for each side since I thought trying to pry the siliconed vents from the NACA duct would break something. All worked OK and I found that the aluminum vents allow significantly more air into the cockpit than did the plastic ones. If only I had known this to start with...

It's your airplane so do what you wish since the plastic vents come with the kit. But after having gone through this exercise I would tactfully suggest you consider the added cost of the aluminum vents and install them in the first place.


Cutting and Buffing Paint Update ...snopercod

Making progress. After sanding out the swirls from the DA and using the Trizact 3000 with a hand pad. I started re-buffing today. I skipped the 3M #1 and went straight to the #2. I think the #1 was just too aggressive - more suitable for removing oxide from a car hood. I think the #2 going to work and I may follow up with the #3 if I don't give out.

I masked off all the control surface gaps and static ports so as not to clog them with compound:  ...


Scrap Stainless Project ...crabandy

I had some scrap stainless, FiberFrax and foil tape so I went to work making a heat shield.

I used my roller a second time (only had it 3 years) to roll my over-sized piece of stainless and fit it over the exhaust.


How Much Air To Feed an Oil Cooler ...Zuldarin entry

"...I will give you my recent experience with the oil cooler inlet. I have a 15 row cooler mounted on the firewall fed by a 4" opening in the baffles. I have found that I can "neck" the flow down to 3" without any performance degradation in flight.

Here is the new cooler fed by a 4" opening that has been reduced to 3.5" with a 3D printed insert"  ...

Trip Write-up: Tangier Island, VA ...Auburntsts RV-10

So we took a $100 hamburger (crabcake) flight to Tangier Island, VA located in the Chesapeake Bay. url

I chose to fly IFR from my home base of Manassas (KHEF) to simplify navigating the convoluted airspace in the area -- the island is almost surrounded by Restricted Airspace used by Patuxent NAS. However, lots of folks do it VFR. However, if VFR it's best to be talking to Patuxent Approach. By going IFR I essentially went direct making for a short 35 min flight from KHEF.  ...


Update on gfb's EGT#4 missing

Sorry for taking so long to get back on this thread. Here is some more data:

- We have adjusted idle mixture (50 rpm rise) and idle (750 rpm) and it is rock solid with the cowl off. No stumbles, just purrs away no matter what we throw at it.

- We cleaned out the spider/flow divider per AFP instructions and now EGT/CHT are rock solid for all cylinders. There is very little divergence between the 4, with maybe 50-70 deg egt delta.

- As soon as the cowl is on i start getting misses/surging. I talked to Don @ AFP and he thinks I am not getting enough airflow over the engine while the cowl is on at idle and I'm getting fuel boiling in the stainless spider lines. I am trying .023" nozzles to see if that helps.

Any pointers on increasing airflow at idle? I will be instrumenting the top cowl area with an RTD to see what temperatures are in there. Don indicates that if it's much higher than 130 I definitely have fuel boiling in the lines.

JetA Mixed w/100LL Experiment ...TimO

"After leaving the 100LL and Kerosene sit undisturbed for 3 days now, it's still 100% unseparated. I don't believe it actually will ever separate. I see it highly unlikely that even after a long amount of time it would separate and collect at the bottom of the tank by the inlet. I have nothing better to do with my jar of fuel, so I will just continue to let it sit and see what it looks like in a few weeks."


Supertracks Canopy Track Extension

There is a slider in Monk's hangar getting some love that has this Flyboyaccessories.com item (link).  I'd never seen one in person, so I thought I would take a few pics for anyone interested.  Looks like it's much easier to access the baggage compartment.

Rethinking personal minimums ...Ed Wischmeyer

On the summertime IFR thread, there was a comment about personal minimums. Rather than bury this response at the end of that thread...

If you think about the challenges one incurs on a flight, you don't want too many challenges on the entire flight, and you don't want too many challenges at one time.

So if you're tired, that's a challenge. Turbulence on the entire flight is a challenge. Dodging cumulus buildups for the entire flight is a challenge. An unfamiliar airplane, or being out of currency enough that you're a bit uncomfortable is a challenge. Pressure to get there is a challenge. So this flight might be a good candidate for being cancelled, even if it's VFR. When I had my RV-4, I counted challenges as "gray areas," and cancelled flights if there were too many gray areas.

Now consider an instrument approach but well above minimums. Unfamiliar ATC can be a challenge, as can be a strong, gusty crosswind, and a wet runway. Low visibility but still above minimums can make it a challenge. Trying to figure out alternatives when the published missed approach procedure goes right through a thunderstorm is a challenge. Lots of challenges at once can be reason to avoid that situation.

So the point of personal minimums is not appropriately discussed in the context of just approach minimums -- you should be able to fly any approach to minimums if you have to. A more appropriate set of minimums are: how many total challenges on the flight; and how many challenges might you encounter at once.

This concept was written for the original Eclipse Jet flight safety manual.

Kissing the belt-driven alternator goodbye forever  ...Hartstoc

I thought some of you might take interest in the process of complete removal of the belt-driven alternator from my RV-7A, including the drive pulley cast into the Lycoming flywheel. This link will take you to a photo album with detailed captions illustrating that process and discussing some of the many advantages.


Sub Panel - Check my layout

VFR Dynon Skyview single screen system with a pro x hub from Approach.

This is what I am thinking for my sub panel layout. I should be able to reach everything on the sub panel through the screen hole in the panel and I think there is enough room for all the connectors as layed out in the photo below.

The only other two items that will have to go further on the right side is the transponder and the back up battery.

Let me know if you see anything I am overlooking.


Monty Barrett

I'm sorry to report the passing of Monty Barrett, one of aviation's best.

It's been a difficult week for the whole family. I would not expect anyone to answer the phone at Barrett Precision Engines until after the funeral (Wednesday, in Shawnee, OK), or perhaps a bit longer. Allen and Rhonda do expect to keep a normal Oshkosh schedule. A memorial service is anticipated after OSH, in Tulsa.

More later.


Panel Upgrade ...Jaudette

I just upgraded my 7a with the EMS D10. Absolutely love it after about 30 hours of flying behind it. I did a video for those of you looking to upgrade.


Can of Worms- O-360 CS Hartzell Setting Advice

Okay, so as the title suggests, I know I am opening a can of worms here. But single engine piston—and especially constant speed propeller stuff—is new to me, and if I’m being brutally honest with myself it’s a little bit mystifying.

I have flown jet aircraft for years, and between the Airbus I currently fly, and the U-2 which I flew in the Air Force, I feel pretty stoopid when I have to actually think about what my engine’s doing. Heck, in the U-2 (yes, they’re still flying), you push the throttle to “mil” on takeoff and usually leave it there until descent. Now I have not one, but TWO more levers to think about.

I bought my first plane, an RV-6 with the above eng/prop setup a few months ago. I understand the basics, and have flown my plane a lot using a formulaic approach to settings, but I need more info. I shoot for <= 380 CHT, and my usual flying is at 6500 or 7500ft in the SF Bay area. I find my MP at cruise and full throttle is 22-2300, and I set the prop at 2300. Then I lean until peak, keep going until slightly rough, then back in a couple turns. I end up with about a 1250 EGT. Seems like about 130-140 kts IAS is where she’s happy.

Am I in the right ballpark? I’m not worried about how fast I can go; I want to keep my engine happy and dependable for as long as possible. I looked for threads here, and surprisingly didn’t see much. Also googled the **** out of this, and found some great advice for fuel injected 540s. Again, not much for our setup.

Fire away.

RAF Pilot and RV-3 driver

Dennis Cullum passed in June 2018. He learned to fly in a Tiger Moth and graduated to an RV-3 he build 20 years ago. In between he had some Meteor time with the RAF. Dennis was a member of EAA Chapter 14 and was a true gentlemen, offering his assistance without request. He helped me with my RV-3 and I was nearly the completion of my condition inspection and hoped we would have some formation time. I guess that will have to wait. Blue Skys Dennis.

Dennis was also the channel navigator in the 1959 Arch to Arch race from London to Paris.

Summertime IFR in the RV-9A ...Ed Wischmeyer

So the plan was to fly from Savannah, GA, to Cedar Rapids, IA, to visit old (and getting older) friends before change made it impossible. Summer weather in the southeast makes such trips easier to cancel than to actually fly.

Surprisingly, the weather on the first leg was forecast to be pretty good, although I waited for some very low IFR to burn off a bit -- a Gulfstream pilot friend doesn’t fly his single engine plane over ceilings less than 1,000 feet in case the engine quits. I went IFR at 6,000 on the first leg, as that let me climb through the clouds without looking for a big enough hole, and it got me into cooler air.

Although it was early, I got a really good burger at Shifters near D73 in north Georgia. When I told the lady I was flying to Iowa, she asked if I was going to drive down to Atlanta and catch a flight. Oh. As the conversation evolved, she said that she had once flown on a thirty seat plane which she described as a “crop duster.” Ahem.

For the next leg, I filed IFR direct at 8,000. My physiology, for whatever reason, wants oxygen much lower than other folks’, but I was ready, and had everything plugged in and tested before takeoff. As the picture shows, the second leg was not direct in any real sense of the word. At 8,000 feet, I was mostly skimming the tops of the cumulus clouds (bases around 3,500 feet), and could usually see the ground somewhere around me.

When I did go through a cloud, tops at nine or ten, it was a ride, but doable. I would usually turn off the autopilot to get additional experience in hand flying. Each bump was a minor upset, and being able to change frequencies while doing that was a minor, a very minor, triumph. The workload was high enough hand-flying the plane that there weren’t very many brain cycles left over for anything else.

On the second leg, there were a few serious storms directly on my route, tops in the mid-forties (really serious storms) so the question was whether to zig around them to the north or to the south. The radar showed a number of measles splotches forming on the southern zig, with great potential for forming an impenetrable line, so I zagged to the north.

On that northern zag, there I went through a few buildups, maybe to ten thou or so, that gave me a >ride<. The workload was high and although the bumps weren’t that bad, the up and downdrafts were beyond my ability to hold altitude within 100 feet.

Then came another cloud, with friskiness that I didn’t see coming, updrafts and downdrafts, bumps being the least of my concerns. It was beyond my ability to keep the plane anywhere near where I wanted it to be, so I turned on the autopilot. To my surprise, the Garmin G3X autopilot did an excellent, incredible, unbelievably good job of holding altitude and, at one point, recovering seemingly immediately from a gust-induced 30 degree bank. (Having given credit were credit is due, there are other things that the autopilot doesn’t do nearly as well as I can do hand-flying, annoyances that I think would be easy to fix. Then again, talk is cheap…)

And when time finally came to descend to the airport, IFR made it easy as I didn’t have to find a big enough hole.

So what’s the takeaway, at least for me:
• IFR in cumulus clouds of any size can be challenging;
• The autopilot is a go/no-go item for me, even though I will not attempt a flight that I think I can’t hand-fly;
• Even the seemingly large deviations added little flight time. And the least fuel reserve I had on any leg was two hours;
• Don’t fly IFR around cumulus clouds if you can’t see what you might be going through. On the third leg, I started the diversion maybe 50 miles away, based on what I could see. And a visual picture is worth so much more than uplinked NEXRAD or center advisories on what their radar sees.

Could I have made this trip VFR? Probably, bouncing along in hot, humid weather under the clouds, avoiding rain shafts and ugly looking clouds. And with GPS, it would be relatively easy to find a nearby airport in case I needed to land right away.

As they used to say on TV, be careful out there…


Spring break ...Skip RV-4 #1904

My o-320 B3B broke both the inner and outer #1 intake valve springs today. It does not run well in this condition and I do not recommend it for the serenity of you flight. Fortunately the closest airport had a great couple of guys in the maintenance shop who found the problem and had the broken springs replaced in under two hours.

  Hope you had a nice July 4th.  Susie and I spent the day out at the hangar replacing the fuel pump on her car (took awhile for it to get here).  All squared away and replaced, the car washed, and the spousal unit is happy to have it back on the line.  I've never replaced an in-tank pump before - a fun project actually.  Saved at least $1,000.  Should be good for another 137,000 miles <g>.
  On to the broken sprinkler system - confidence high.

First Freedom from Gravity ...sbalmos

It was more than a first flight. It was first freedom. Freedom from the tyranny of gravity. Today, my plane celebrated its Independence (from Gravity) Day! Kind of appropriate, right?

The first flight was much shorter than planned, just over 15 minutes and one time around the pattern. Definite extremely high CHT issues, especially on #2, to work on with the baffles. And I think I have a loose pitot tube fitting somewhere - lost airspeed indication some time after I passed 25kts and switched my attention back outside to lifting off. Oh well, no biggie. Everything handled smoothly and engine sounded fine. Fly with your senses, not your sensors.

What little time was spent in the air was incredibly smooth and stable, and even a great first landing (albeit a bit shallow).

A huge amount of thanks to Scott Hersha, who flew chase in his RV-8 and checked for anything flapping around or pouring out the underside (thankfully no). Thanks to Steve Melton for snapping the exhausted RV grin pic that I'll get and post up some time soon. Thanks to Tim Ribble for great transition training out at Chesapeake, VA in his RV-6A. And to everyone else in the RV Community, both at HAO and online here, who's lent assistance at any time during the past 6.5 years, THANK YOU.  ...


Initial Flight - RV8

First flight for N842FM at San Geronimo Airpark (8T8).

I had a highly experienced RV pilot do the initial flight. He said it flew smoothly and had no roll bias. 2 issues: prop RPM indication problems and both radios were weak transmitting.

I'll will have to wait until the weekend to troubleshoot. I am sure there will be more tweaking/adjusting/fixing still to come.

The journey of the build to the maiden flight has been an awesome experience (still learning). Though there have been many, many, many, many, many frustrations and challenges, I am glad I was able to see the project completed (major help from my mentor-Les Bourne).

A gas contaminated with jet a

So today I had less than a cup of jet a mixed into one of my tanks of 16 gallons of 100ll on accident when someone grabbed the wrong fuel hose. The pump was not on but there was residual fuel in the nozzle. Surprisingly they seemed to completely mix and not separate. I always thought that jet fuel would separate out but the mechnic at the field said that jet-a and 100ll mix. Weird, does anyone have an idea what to do with this? if I have to dump 16 gallons of 100ll gas, where does it go? My guess is the engine wouldn't even notice this small amount of jet a, anyone had experience with this? I'm sure lycoming has a bulletin advising what to do?



Tire Split

Obviously I’m grounded till new tires but has anyone seen this and what might have caused it? The plane is new to me so not sure if it’s age of tires or what. Tires have 170 hours with good tread life left. I don’t remember seeing these cracks last time I had the fairings off about 20 hours ago. Aircraft was completed in 2012.




July 4, 2018.   Issue #4,602.

In Congress, July 4, 1776.

The unanimous Declaration of the thirteen united States of America, When in the Course of human events, it becomes necessary for one people to dissolve the political bands which have connected them with another, and to assume among the powers of the earth, the separate and equal station to which the Laws of Nature and of Nature's God entitle them, a decent respect to the opinions of mankind requires that they should declare the causes which impel them to the separation.

We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.--That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed, --That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness. Prudence, indeed, will dictate that Governments long established should not be changed for light and transient causes; and accordingly all experience hath shewn, that mankind are more disposed to suffer, while evils are sufferable, than to right themselves by abolishing the forms to which they are accustomed. But when a long train of abuses and usurpations, pursuing invariably the same Object evinces a design to reduce them under absolute Despotism, it is their right, it is their duty, to throw off such Government, and to provide new Guards for their future security.--Such has been the patient sufferance of these Colonies; and such is now the necessity which constrains them to alter their former Systems of Government. The history of the present King of Great Britain is a history of repeated injuries and usurpations, all having in direct object the establishment of an absolute Tyranny over these States. To prove this, let Facts be submitted to a candid world.

He has refused his Assent to Laws, the most wholesome and necessary for the public good.

He has forbidden his Governors to pass Laws of immediate and pressing importance, unless suspended in their operation till his Assent should be obtained; and when so suspended, he has utterly neglected to attend to them.

He has refused to pass other Laws for the accommodation of large districts of people, unless those people would relinquish the right of Representation in the Legislature, a right inestimable to them and formidable to tyrants only.

He has called together legislative bodies at places unusual, uncomfortable, and distant from the depository of their public Records, for the sole purpose of fatiguing them into compliance with his measures.

He has dissolved Representative Houses repeatedly, for opposing with manly firmness his invasions on the rights of the people.

He has refused for a long time, after such dissolutions, to cause others to be elected; whereby the Legislative powers, incapable of Annihilation, have returned to the People at large for their exercise; the State remaining in the mean time exposed to all the dangers of invasion from without, and convulsions within.

He has endeavoured to prevent the population of these States; for that purpose obstructing the Laws for Naturalization of Foreigners; refusing to pass others to encourage their migrations hither, and raising the conditions of new Appropriations of Lands.

He has obstructed the Administration of Justice, by refusing his Assent to Laws for establishing Judiciary powers.

He has made Judges dependent on his Will alone, for the tenure of their offices, and the amount and payment of their salaries.

He has erected a multitude of New Offices, and sent hither swarms of Officers to harrass our people, and eat out their substance.

He has kept among us, in times of peace, Standing Armies without the Consent of our legislatures.

He has affected to render the Military independent of and superior to the Civil power.

He has combined with others to subject us to a jurisdiction foreign to our constitution, and unacknowledged by our laws; giving his Assent to their Acts of pretended Legislation:

For Quartering large bodies of armed troops among us:

For protecting them, by a mock Trial, from punishment for any Murders which they should commit on the Inhabitants of these States:

For cutting off our Trade with all parts of the world:

For imposing Taxes on us without our Consent:

For depriving us in many cases, of the benefits of Trial by Jury:

For transporting us beyond Seas to be tried for pretended offences

For abolishing the free System of English Laws in a neighbouring Province, establishing therein an Arbitrary government, and enlarging its Boundaries so as to render it at once an example and fit instrument for introducing the same absolute rule into these Colonies:

For taking away our Charters, abolishing our most valuable Laws, and altering fundamentally the Forms of our Governments:

For suspending our own Legislatures, and declaring themselves invested with power to legislate for us in all cases whatsoever.

He has abdicated Government here, by declaring us out of his Protection and waging War against us.

He has plundered our seas, ravaged our Coasts, burnt our towns, and destroyed the lives of our people.

He is at this time transporting large Armies of foreign Mercenaries to compleat the works of death, desolation and tyranny, already begun with circumstances of Cruelty & perfidy scarcely paralleled in the most barbarous ages, and totally unworthy the Head of a civilized nation.

He has constrained our fellow Citizens taken Captive on the high Seas to bear Arms against their Country, to become the executioners of their friends and Brethren, or to fall themselves by their Hands.

He has excited domestic insurrections amongst us, and has endeavoured to bring on the inhabitants of our frontiers, the merciless Indian Savages, whose known rule of warfare, is an undistinguished destruction of all ages, sexes and conditions.

In every stage of these Oppressions We have Petitioned for Redress in the most humble terms: Our repeated Petitions have been answered only by repeated injury. A Prince whose character is thus marked by every act which may define a Tyrant, is unfit to be the ruler of a free people.

Nor have We been wanting in attentions to our Brittish brethren. We have warned them from time to time of attempts by their legislature to extend an unwarrantable jurisdiction over us. We have reminded them of the circumstances of our emigration and settlement here. We have appealed to their native justice and magnanimity, and we have conjured them by the ties of our common kindred to disavow these usurpations, which, would inevitably interrupt our connections and correspondence. They too have been deaf to the voice of justice and of consanguinity. We must, therefore, acquiesce in the necessity, which denounces our Separation, and hold them, as we hold the rest of mankind, Enemies in War, in Peace Friends.

We, therefore, the Representatives of the united States of America, in General Congress, Assembled, appealing to the Supreme Judge of the world for the rectitude of our intentions, do, in the Name, and by Authority of the good People of these Colonies, solemnly publish and declare, That these United Colonies are, and of Right ought to be Free and Independent States; that they are Absolved from all Allegiance to the British Crown, and that all political connection between them and the State of Great Britain, is and ought to be totally dissolved; and that as Free and Independent States, they have full Power to levy War, conclude Peace, contract Alliances, establish Commerce, and to do all other Acts and Things which Independent States may of right do. And for the support of this Declaration, with a firm reliance on the protection of divine Providence, we mutually pledge to each other our Lives, our Fortunes and our sacred Honor.

Had a flight with elevator trim inoperable. Tried a bigger fuse and worked again. After it quit again, I examined the area and discovered the threaded bar between the trim tab and trim motor was catching sometimes on the threads. Used a dremmel to lengthen the slot and problem is solved.


RV-8 and the Grand Coulee Dam ...Steve Rush

Unlike this weekend, last Sunday was a pretty nice day here in the Northwet (spelling intentional). I was able to sally forth over the mountains to see some of the sights and it looked a lot like this:

Fair warning, there is one spelling error in the video.


Carbon fiber Sliding Canopy Skirt ...Joewebb

Just a quick video how I made my alternative sliding canopy skirt..


Build Status Report ...jcarne 7A

Well my rivet buddy decided to go to the mountains today so I started working on the "fun" part of the center section... deburring.

I got half of the 18 ribs done and also decided to take a break at one point to rivet the F-705 bulkhead. I'm REALLY glad I went with the paint before rivet idea, the contrasting rivets looks next level cool to me.

As a tip to others, don't forget there is a rivet under each of the bar doublers that MUST be set first. Luckily I only set two rivets before realizing this.

First Flight for N11XZ, RV-4, #3204 ...SJordan

I'm happy to report that N11ZX took its first flight on the 16th from Deer Valley airport in Phoenix Arizona. 28 minutes of ear to ear grin with little to no problems to report.


Akutan Zero Entry ...Vlad the Amazing

Avatanak island followed by Rootok. For some those chunks of rock mean nothing but for aviators of WWII every landable spot was gold.


South Haven Michigan (KLWA)  ...jjbardell

Trip report / blog from KLWA. I added a summary of sights and food at the top which I will do on all future trip reports.

RV-9A, pilotjohns...Fuselage, part 2 of many

Bending longerons. Those words create fear, at least they did for me. I don't care to beat things with hammers, so I borrowed some longeron bending dies. I added scotch tape to the longerons and spread a thin coat of biolube from the aviation isle of REI. I didn't have a good vise, so I used c-clamps and the old wing crate as a table. I taped the plan's template to the side of the crate. This worked out well.

Using the c clamps, I did the first pass moving the dies about 1 1/2" at a time. The first longeron I had help and went well with very little out of plane bending, but I went thru 12 "el cheapo" c-clamps. For the second longeron, I bought three drop forged c clamps. These are still usable afterwards so worked out better. The rear bend is actually much tighter than the rest, so I had to use three pieces of 1/64" model airplane ply to increase the bend radius of the die.

The second longeron bent easier using the better c clamps, but I had much more out of plane bending. Using some scrap wood and a 2" piece of drain pipe, I was able to roll the bend back into plane. Both are well with the 1/16" tolerance.


VA Aviation Ambassador Program Complete ...Vlad RV-9A

VA Aviation Ambassador Program is completed. Feels good to be in one cohort with outstanding RVators like Rick Solana and others. Did I mention they send a you free leather jacket of great quality?  South Carolina next. Over a dozen airfields already visited and stamped.


Canopy drilling...Carl Froehlich

The issue I've found with drilling the canopy to canopy frame holes is making sure you drill at exactly the right place on the frame to avoid unnecessary stress on the glass.

For the first project (8A) I copied a trick to find the exact tangent point between the canopy glass and the steel frame. After running some standard masking tape very lightly on the frame, the canopy is carefully put in placed and clamped. The result is a perfect line in the tape where the glass touched the frame - the tangent point.

I found out the trick does not work with powder coated frames (first plane was pre-powder coating). There is not enough color contrast between the powder coat and the tape to see the line. The fix was to first run black electrical tape on the frame, and the masking tape on top of that.

The photos show the clear tangent line. Note that the tangent line is not at the horizontal midpoint - the glass curves under.

Next steps:

- With the glass off, use a sharpie to mark the line and then space out where the holes will go.
- Drill the #40 holes in the frame.
- Put the glass back on, check position a few hundred times then drill through the glass into the #40 holes. Clecko.
- Take the glass off and using a unibit drill the glass holes to 1/4" and slightly countersink the outside (more for the canopy bow than the sides as the sides have the fiberglass skirt that gets countersunk for the tinnermans). The objective is for a tinnerman to fit into the glass and then the CS4-4 rivet to fit into the tinnerman - the tinnerman spreads out the attachment force.
- Drill the frame #40 holes to #30.
- The roll bar gets tapped for #6 screws per the plans, but tinnermans again used under the screws on the glass.
- If you hate the powered coat color as much as I do, remove the frame and roll bar for final paint. Reassemble after the rest of the interior is painted.

Have fun,
