Formation Training Clinic = New Pilot?

Falcon Flight, led by the efforts of Bobby Lucroy and Ron Walker, put on a formation training clinic at KGYI just north of Dallas. The initial date ended up being rained out, but the backup weekend turned out okay. The weather did still force a scratch of one practice sortie, but we were able to get in some excellent training and spent some high quality time with our new trainees. Yes, the newbies never fail to invent new ways of messing up, but we keep everyone safe - that's the #1 priority. We took some newbies from the holy-cow-that's-close!!! status to clearing them to join a formation solo. We were also able to complete a couple checkrides with newly minted Leads.

Formation flying is very serious business, but that doesn't mean we don't have a great time along the way. I enjoy the laughter that seems to abound at these clinics and always walk away with new friends, this one was true to form. Everyone is there with the same goals of learning new skills, improving on other skills, and enjoying everything a clinic brings with it.

Our dinner outing Friday night had us all telling stories around the table at a local restaurant. The waitress was able to hold her own with our boisterous crew, and I asked if she wanted a ride the next morning before training started. Makenna made our 6:45 time hack, and off we went with her boyfriend to the airport. This was her first time in a small airplane, and she was thrilled when I gave her the controls. She's a natural. We talked about what it took to be a pilot, and she walked away talking to her boyfriend about maybe making that her path in life as he was doing. Our formation clinic may have encouraged a young lady to find her way to a pilot's license.

Thanks to everyone that came to the clinic and put forth every effort to make it a successful event.



RV8-83772, N1986 ...update


Convert VFR aircraft to IFR

With a Dynon D-180, a non ADS-B compliant transponder, no other instruments installed, what would it take to modify it, to make it ifr capable ?
Only looking for enroute IFR flying in Florida, nothing less than 1000ft ceiling.
I was not the builder on that RV so I cannot do the work, any estimate on time and cost, to do such modification ?

We're All Pilots ...Myron Nelson RV-10

[ed. VERY well written Mr. Nelson.  Thank you for bringing it to out attention. v/r,dr]
An article Myron wrote was published on Avweb. 

"....After having had scores of airline crew overnights in Los Angeles over the last 32 years, in a variety of area hotels, one I stayed in recently had special meaning for me.

As I arose in the morning and opened the drapes, I was presented with a direct view of the approach end of Runway 24L at LAX. It was one of those rare and melancholy moments in life that spur deep reflection. I pulled up a chair to the window just as one of my company's aircraft was gracefully touching down.

My mind drifted back more than 28 years when in a previous life I had a training/evaluating position at SkyWest Airlines. When administering recurrent checkrides in those days, a common scenario was to position the rudimentary SA227 Metroliner simulator position at LAX, primarily using Runway 24L for departures and 24R for the requisite instrument approaches. The simulator itself was physically located in Salt Lake City; however, for purposes of the checkride, its simulated position would be in Los Angeles. Today’s modern flight simulators can be virtually positioned at any major airport in the world."   continue

Elevator Mismatch (Drilling Mistake)

So, looking for some sanity or help from the community.

Part of mounting the elevators requires having them both at neutral, and using a guide block / clamp to make sure that they are drilled both perpendicular and even to each other.

Unfortunately, the clamp I chose to use didn't quite hold against the will of a new #16 drill bit to wander.

I now have a hole that is off by a slight amount on the left elevator, and the result is that the elevators are about 1/4 inch off at the foremost section where the weights are.

I'm looking for recommendations on how to recover, here's some things I've considered:

1. Rebuild one of the elevators - I simply don't see how without massive work I could replace just the horn because the skins won't peel back nicely anymore now that they are rolled.
2. Fill the hole with weld, and redrill the elevator horn
3. Set neutral to split the difference (so one rides 1/8 low and the other 1/8 high)

Any help or suggestions would be GREATLY appreciated... pictures here:

(Marvin McGraw reply)
I welded in a small piece of metal the thickness of a washer and re-drilled. Your not the first. Weld and move on, it will be okay.


RV-6/12 Builder Dave Gamble's Day in the B-2 Sim

I continue to be amazed at how much building an airplane has enriched my life with both new opportunities and new friends. Those are often interrelated and here is a case in point: I got the opportunity to fly the B-2 Spirit flight simulator at Whiteman AFB through a Friends and Family kind of thing, the friends being a father and son pair that I met as a consequence of building my 12. Readers of my Blog will know the father as Pete.

Pete’s son Keith was very interested in aviation at a young age and was interested in an RV-6 ride, which he got, and he flew with me again once the 12 was done. Both were fun and interesting, but the 2nd flight wasn't with an aspiring teen, it was with an accomplished and confident 1st lieutenant with stories to tell about flying an E-3 Sentry. Ironically (or coincidentally - I sometimes struggle with the difference), most of my questions were about refueling.

I was invited to attend his graduation from B-2 Initial Qualification Training and subsequent transfer to 393rd Bomb Squadron. It was a 9 hour drive, but there had been mention of getting some seat time in the B-2 simulator. That made an easy decision even easier.

Damaged thread at engine case oil return fitting

Engine is an O-235. I finally traced an oil leak to a damaged thread inside the case at the oil return fitting.

Is the best solution to run a tap down the thread? If so, any tips on doing this? Since it's inside the engine case I'm concerned about screwing this up.

Any suggestions you have would be appreciated.

Status Update ...RV7ForMe

Well, the rebuild RV7A is complete and so I return to building a few parts that I have given buddy so that he can fly this summer... Like the VS.

Yup I just build my second one of these.

You would think it would go a lot quicker, but for some reason that was not really the case. With Priming and de burring all in was about 20 hours. Even though I knew what I was doing this time around and didn't have to think about it to much... So for those of you that have stated they can build a whole empennage in a weekend. I wonder how much de burring is included in that.

Or I am simply very slow.


RV-12 Mini-Flight Review

The RV-12 has been out for some time now and I finally had a chance to fly one the other night.

I must say, I was really impressed by the -12!

What a nice flying aircraft, very light on the controls, much lighter than my RV-9. I would say it is more in line with the -4 than a -7. Kind of like a -7 at low speeds because of how quickly it responded to stick and rudder input.

Very well Balanced in its control harmony. Probably better balanced than a -7 or -8. (Sorry guys!)

Off of grass with no wind and two 200+ pound (I'm not saying how much above 200 the passengers were but it was significant.) people and half tanks we used up probably 1000 feet, maybe less. (Typical soft field technique; one notch of flaps from brake release, full aft stick, as soon as the nose wheel is off the grass release back pressure but keep the nosewheel off the turf, once we broke ground I accelerated in ground effect until speed built up and then pitched for Vy. The 1000' included the flight in ground effect.)

At Vy we were still climbing at a solid 700 FPM. Stunning!

I had heard this before but didn't believe it, the visibility out of it is so much better than in my -9 or in a -6 or -7!

Landings were very easy. With our two big 'ol butts in there I used 60 knots, which was pretty fast on final and full flaps. Touched down on the mains, holding the stick aft for a full stall landing with the rollout with the stick full aft. By mid filed 1200' we were adding power to taxi to the end to take off again.

Those of you who are building, keep pulling those rivets! It is worth the effort!

Those of you who are thinking of building a -12, write that check!

I just can't get past the fact that the -12 out performs a Skyhawk so easily!

If only there was a tailwheel version. Oh Mitch, can we talk?

SkyTec 149NL separating - Keep an eye on them

During my last oil change noticed some dark staining around where the motor meets the gearbox on the starter. Grabbed ahold of motor and it was loose!
There are some bent tabs to hold the two screws in place no locktite I could see. Pulled in a part and cleaned it up replaced the tabbed washers with lock washers (unlikely to help much) and blue locktite.

Due to the bad ground it was getting it was much more effective when starting it up. Spun up much faster, since it happened slowly I had not noticed it spinning slower.

Will keep a closer eye on now see how it does.

Best Day Ever ...woodmanrog

Al had never ridden in a small plane. What could be a better experience than to fly in a new RV14A to the final "Old Farts" fly in at Venice, Florida. Perfect weather, and attendance of 50 plus varied aircraft and great food at Sharky's on the beach. He couldn't stop saying over and over what a thrill the experience was. Al still has the grin on his face today. Oh, by the way, he didn't need the T.P.


9A Longitudinal Dynames ...vlittle

My 9A was difficult to trim due to the phugoid response. What fixed it was careful elimination of all control system friction.

The biggest contributor was friction in the elevator hinges, including the main bearing that connects the elevators.

If any of the bearings exhibit side load from the hinge brackets they will bind. Carefully choosing shim washers at the hinge points eliminates this. It's meticulous work but it makes a difference.

Disconnect the main pushrod from the elevator bellcrank while doing this. When reconnecting the pushrod, make sure there are no side loads on the bearing as well. There should should be just enough shim washers in place so that there is no distortion of the horns when torquing the through bolt.

Almost Touch 'n Gos (ATnG)

A short flight Thursday morning before 'quality time' with the computer.  Ever the tightwad, I tend to as of late bring the RV into ground effect and get the tires within a half foot of the surface, then slowly add the power back in and raise the flaps.  Concentrating on keeping the plane lined up with the centerline as the flap and power change is a satisfying challenge - in some ways even more satisfying than the actual landing.

Tires never touch the surface, so they, and the brake pads, last longer.  Seven 'landings'....one set of tire marks. ;^)

Sadly, on one of the upwind/crosswind legs I spotted a dead cow in a washed out area in the pasture next to the airport.  Here in GM.  There were a dozen or so vultures already around it, so if you're flying here heads up for large birds.  Rob Reece (our apt mgr) called the guy who takes care of those cattle and let him know.

Wishing you and yours a happy, safe and RV-filled weekend.


New builder in Reno

After 20 years of dreaming about building, I finally took the plunge and started the empennage. I have a tech counselor visit in the works with Ironflight, but thought I'd see if there is an experienced builder in the Reno area willing to critique my work before that visit (cold beer on hand) to save me any pending embarrassment!

6A and IFR ...Planecrazy232

Many people ask about the RV6 as an IFR platform and I find it easier than the spam cans. It goes where you put it. Here’s my latest practice under the hood with a safety pilot. The first approach to the hold was with “George” in control, all the rest exiting the hold was hand flown to minimums. The odd circle at the bottom is when approach control canceled my clearance because of a Citation hot on my heels. Equipment is all G3XT and the latest software. Works like a champ.

Status Report ...jcarne RV-7A

Here we are after a second coat and a third coat to fill low spots. The shape is quite close as compared to the Van's fairing. It is time to sand and shape a little more and then I will see if I have any low spots to fill but overall it is coming out pretty decent. The edges in the picture look a little rough because I shaped quite a bit to get it tangent to the tail feathers. The sanding will take that chipped look out.


So close yet so far - Throttle and Mixture cable woes. ...WingnutWick

So after the new RV-6As mixture bound and bent for the second time I decided to take it upon myself to replace the quadrant style cables that were wrapping around the carb to make the direction of travel correct and go with the standard RV-6 setup. I ordered the RV-6 throttle and mixture cables from vans and the RV-6 O-320 bracket.

Woe #1: the bracket did not fit correctly and I had to cut and bend it to meet it from pressing against the oil pan. Then I had to dremel out a hole for the oil drain to go through. Not pretty but figured it’d due the trick. I chalked the bracket not fitting great due to the motor being an H2AD and kind of an odd ball engine, but I don’t really know.

Woe #2: Drilling the holes. With everything mounted on I couldn’t use a template so I had to eyeball it. The battery is in the inside of the cockpit centered between the rudders and in front of where they say to put the mixture control so I elected to have the mixture come out to the right of the battery below the throttle thinking that bend wouldn’t be enough to hamper the movement of the control. A royal PITA working under the dash like that with my 6ft4 frame. Plus there is this shield that is behind the battery that I had to work through.

Woe #3: Finally got the cables routed and through the firewall. And all the hardware put in only to find that the throttle cable doesn’t reach the bracket hole, let alone the throttle arm to allow for full throttle. This is bizarre because it’s pretty much B-lining straight from the dash to the firewall and to the carb. Furthermore the mixture doesn’t want to travel all the way out (lean). Not sure if that is binding due to the small curve but I’ve seen more aggressive curves on other’s planes work.

Before I went putting more holes in the firewall I want to check in and see if anyone know what the heck is going on here!? Inputs, insights, suggestions always very much appreciated!!

Thank you all!

Wing walks came off in flight

I installed one of the replacement wing walks that flew off in flight.

Between Goo Gone, Prep-Sol & a credit card, all of the old adhesive was removed w/o damaging the paint. After removal, per Blake's instructions, the surface was repeatedly cleaned with 50/50 water alcohol.

"Snopercod's" suggestion to use 3M Primer 94 was absolutely brilliant. You wipe it on, let it dry, then install the wing walk. Make sure someone is helping you so the wing walk material goes exactly where it's intended the first time.

I tested the adhesive idea on another painted surface and the primer radically improved the adhesion. Better to spend $18 on a pint of primer than do this job again.

I waited a day and flew @ 160kts. The wing walk remained so now I will do the other wing.

Thx folks & thanks to Flyboy for their great customer service.

RPM stay out zone

I have the YIO-360-M1B and Hartzell CS Prop that you buy thru Vans on my 7A. Am I suppose to have a stay-out zone on RPMs between 2150 - 2350 where continuous use is not advised? Or a "yellow" stay out zone?

I've seen this in other POH's but I can't verify it is necessary. If true is this a attribute of the engine/prop combo? Or use of this engine/prop on an RV7A?

Thanks for clarifications.

New 300-72RV Series™ Constant-Speed Composite Propeller from Whirl Wind Aviation

...VAF advertiser press release

(Note: “New” refers to April 23, 2019)
Whirl Wind Aviation, has developed a new 3-blade composite constant speed propeller, the 300-72RV Series™, for Lycoming (Lyc 0360 - IO390) powered Van’s RV style aircraft.

Whirl Wind Aviation is now taking orders for and delivering the new 300-72RV Series™ constant-speed propeller.

The 300-72RV Series has been several years in the making, and performance results have been very good. Pilots have noted an increased take-off acceleration, and an increased rate-of-climb with the same top speed as Whirl Wind's legendary 200RV Series™ propeller.

At just 36 lbs, the new 300-72RV Series™ propeller is the lightest weight constant speed propeller in its class. Most impressive is that it's a 3-blade propeller that is 5 pounds lighter than Whirl Wind’s 2-blade 200RV Series propeller due to the 300 Series' optimized and compact design. ...

Build Update ...PilotjohnS

I decided to install the new Flap Motor from PH Aviation. This flap motor replaces the stock Vans flap motor. I like the new one because it has a built in up and down stop, built in position pot to interface with the G3X, has a different motor that may not suffer from grease contamination, and the shaft doesnt rotate so no need for that funky safety wiring.

The installation is a little different than the Vans version.

First off, I made the F767 plate a little longer than the original to make sure the motor support brackets were completely contained on the plate. This eliminates a spacer and also provides more strength for the motor supports. In the picture is the new F767 plate, and the stock F785A/F785B Backrest Brace and the stock F766A/F758 Flap actuator channel.

Plus, I'll get some more experience with fiberglass before I do the canopy skirt.

Cables through firewall

Hello all,

I am changing out my girlfriend's RV-6As throttle cables as the previous ones were unacceptable bowden type coming from a throttle quadrant and wrapping around the carb to have the correct movement. Very dubious.

I have removed the quadrant and putting in standard push-pull type controls from Vans. I have the old b bulkhead cable safe locks that were used on the other cables but they are too small, especially to fit around the threaded end that has to pass through the firewall.

What is the standard equipment to use for passing these through the firewall?

Thank you!

Am I looking for a rare bird?

Hello everyone.
I am new to this forum (posted an intro in the general section a few weeks ago).

After some research and talking to a few of the real experts (Ron Schreck & Vic Syracuse), I think I might be a good candidate for an RV, specifically an RV-8A.

I am not in a position to build, so I'm looking for a flying aircraft built to a very high standard (want to feel comfortable about the structure when fixing whatever maneuver I've made a mess of ).

As I am hoping to do aerobatics as well as all the other things the RV does so well, I am looking for an RV-8 (ideally an 8A) with a fuel injected engine and hopefully also a CS prop. So IO-360 or AEIO-360 with CS in an RV-8A.


- Is this a rare combination?
- What is the best way of finding such a beastie? (I have posted in the classifieds, but those move quickly - no response yet).
- Realistically should I plan on a year or two to find my aircraft?

I would love to hear tips, suggestions and thoughts about finding the "perfect" (which I know doesn't exist) aircraft for me.
I have already decided to have Vic do the pre-buy - I know this is a critical step when I get to it.

Thanks to all who contribute their knowledge on these forums.

Trip Write-Up: South Africa Air Safari 2019 ...RudiGreyling


This is just a short Collage of pictures of our air safari through South Africa.

During the March School holidays us family took our RV Zulu 10 on a 12 day air safari through RSA.

Plan was to fly from The Coves near Johannesburg and fly the Vaal river from Parys to Kimberley then the Orange river all the way to Augrabies Waterfalls.
This may sound strange to foreigners, to fly a river, but in a water scarce country to see this river cut through and give life to this arrid piece of our country is beautiful.

Then head south to the desolate Verneuk Pan, a salt pan, cut east to De Aar then fly the Vanderkloof Dam into Gariep Dam.

Then Cut to the coast and fly the wild coast, stay at Wavecrest. Onto Margate for a couple of days.

Then back home via the Majestic Drakensberg Mountains right next to the escarpment at Lesotho.


New guy checking in ...Ryan Dodde II

Greetings. I guess I would qualify myself as “a long time listener, first time caller” to the Vansairforce forum. My foray into experimental aircraft began some 50 years ago. when I was about four or five, my family was on our way to church when we drove past someone’s garage with a half built Piper Cub poking out. That image stuck in my head and was the seed that started this adventure. It has also been the carrot that I’ve dangled in front of myself while I was obtaining my medical degree, starting my practice, putting my daughter through school and building our house. I have finally come to the point where I can pursue my ambition of building an airplane. I purchased a RV8 QB kit and I am knee deep in the construction. I have completed the empennage and ready to move on to the wings. Both my father and grandfather were tool and die makers, however, metalworking does not appear to be an inherited skill. I find that I have become somewhat frustrated in the effort that it has taken to get my build to the quality that I expect in my other pursuits. If there are any builders in the Holland, Michigan area, I would appreciate it if you would send me a shout. I have been very impressed with the support of the Van’s community, which is one of the reasons I chose this airframe.


N8402 flies after 4 1/2 year build ...JHartline

On March 29th slow-build project S/N 140184 was officially pronounced an airplane by Vern Darley. Great guy and tons of RV-specific knowledge. I was very confident in my work after his inspection. ...


RV Law of.... ...Brian Morrow entry

Van's Time Axiom:

The need for any Van's part will inevitably be discovered at precisely 5:05PM Pacific Time on a Friday.

Corollary: If the part is urgently needed and causes your plane to be grounded, the Friday in question will precede a Monday Holiday.


Ground Shot ...Steve Hamer


5 years!

I hit the flying for 5 years milestone. I now have 653 hours. Basically, one third of the way toward TBO, so check back in 10 years.

So now I have been officially flying more years than building. I think I like flying more. Still have some tinkering to do on it, but I don't think I would have changed much if I had it to do over again.

On to the VS!

After mounting the HS on the fuselage last time I realized I still hadn't drilled the elevator horn lower hole for the push tube. So I took it off, drilled the holes and remounted with the elevators. I also decided to finish the trim tab hinge pin and safety wire it (not sure why Van's doesn't give you the right length hinge pin until the fuselage?).

RV Series - RV/IAC Aerobatic Competition Standings ...Ron Schreck

A small turnout for the Carolina Boogie this weekend. Weather and Easter may have played a part. But those who came had a blast! Chris Crawford brought his RV-8A out for his very first contest and posted a very respectable 71.93% score. We had a great practice day before the contest and I coached Chris from the ground. He showed improvement on every flight and went home with a trophy and a great deal of new-found confidence.

Status Report ...jcarne

Well I haven't been sittin here doing nothing since my last post. Since I'm waiting for it to warm up before cutting the canopy I decided to mount the tail. Yesterday I finished mounting the horizontal stabilizer, it takes quite a bit of time to get the bolt holes just right but man they came out perfect, couldn't be happier with them.

After careful marking I used 12" drill bits starting with a #40 to get the initial hole. You can see I placed an engineering square next to the bit to make sure it was square with the fuse. This method works well. The final hole was drilled with a 3/16" reamer as it was just long enough to give drill head clearance. ...


Things I wish I'd saved from the build ...jpowell13

I've got my right fuel tank from my 6A off for what must be the 5th time to fix leaks and run more wires and AOA tubing. I kept wishing I had saved the fuel tank cradle until today I finally built another one.

If you're building, be sure to put your fuel tank cradle together with screws so you can break it down and store it easily. You will almost certainly use it again. If you don't need to fix a leaky tank, you can turn it upside down and use it for a table to serve your favorite beverage.

Be sure to save every tool and scrap of wire you used in wiring your plane as well. There seem to be no end to panel and cockpit upgrades that require a little wiring.

And it's amazing how often all those little bits and pieces of scrap aluminum come in handy. And, for goodness sake, hold onto your plans and construction manual. In fact, just save everything, if you don't need it, your buddy will. John

(Spotlight reply - Miles)
I have a bin with all my aluminum, scraps from the project. I keep everything bigger than a 3/8” circle (that's the smallest piece you can put a #40 hole in with adequate edge distance)


Pilot as a Day Job ...David Z

I was thinking the other day, how many builders and RV pilots also fly professionally? Also, in what type of operation and aircraft?
Did the systems or layout on the plane you fly at work affect the layout or systems of your RV?

I'll start, I'm a Dash 8-100 Captain working for a small airline in Northern Ontario Canada flying to remote gravel airports. As for shamelessly stealing from work planes, I have flown various models of King Airs and the 1900 previously. I'm considering stealing ideas from the Beechcraft electrical system logic for redundancy. My build is pretty early on, lots of time to change my mind.

P.S. Obviously the fighter pilot guys win the "cool" contest with F-15s, F-16s and such. <g>

  Spent Wednesday bouncing around between layers in TX/OK/KS on a side job before the forecast TSRA arrive (pic below).  Very little ground seen.  Pushing this edition out before the storms arrive.  Forecast is for GR - hope the frozen baseballs stay away.  We don't like those very much...
  There was an RV on the ramp outside at KDTO when we taxied back in.  I hope that person moved his plane inside!



Houston area monthly lunch (April 2019)

The third weekend is upon us again, so let's plan on hitting up Carl's for some BBQ at Weiser this Saturday (4-20) at 11:30. I may be a little late (flying Young Eagles at IWS in the morning), but I'll be there.

RV8-83772, N1986 ...Roarks


Well today is the start. After dithering on a decision, having the plans preview book for 6 years I called today and ordered the tail feathers.

It's been a long time coming. I had just finished my Aerospace engineering degree, I finally got my private, then got distracted with helicopters for a while. Thought I would consider an RV... Took the eaa sheetmetal class... It was good but I thought there should be more so I got my A&P certificate. Now I teach sheetmetal at the part 147 mechanic school!

Should be an interesting ride. Which I could fast forward to see the end of this thread!


Another RV-14A takes to the air ...Turner Billingsley

Today was the big day. Vic Syracuse came down and did the inspection, issued the S.A.C. and flew first flight. We identified a few issues, but that just means more time tinkering. Overall a great day, having the "Additional Pilot" on the first flight was immensely valuable.

See blog for obligatory video and paperwork photo!


Garmin G3X (GDU 370/375) Pending Software Release ...g3xpert

We wanted to give G3X owners a heads up that there is a subset of GDU 370/375 displays which are affected by the GPS week rollover event which occurred on April 6.

Any affected G3X system is still fine to use and the GPS data including navigation and displayed time is not affected, but in the few places where the date is exposed, like in the flight data log, the time will be correct, but the date will be incorrect.

If you want to see if your system is affected, select Menu, Menu, System Setup, Date & Time and you can see the system date and time.

We have implemented a software fix and are testing this fix before doing a maintenance release soon.

We apologize for any inconvenience this may cause for those affected.

There are no known issues with G3X Touch systems.

My introduction ...knievel

7 years ago I was early in my PPL training, pre solo. I had grown accustomed to the stodgy appearance and 2,000' take off roll of my club's overloaded Cessna 150. (Instructor and I put it over gross)

My instructor and I were taxiing for takeoff. KANE Blaine, MN. A plane from the other side of the field got takeoff clearance first so I held short. Oh my God it was beautiful. Low slung, tail dragging thing looked like it was going 200 in the taxiway. "What is *that?" I asked. My instructor replied "oh, that's one of those RV's. You build them at home. Watch it take off". It rolled forward what looked like 100' and then left almost vertically. My jaw hung slack, I knew I had to have one.

I've lurked here every since, dreaming but knowing it was outside of my space and finances. Then my boys got into that youth sports age and I had no time to fly at all. I dreamed of an 8, but knew the 9a would better suit my intended mission if touring with my wife. (Who made it to almost 300' agl in the c150 on her only flight before demanding to land). The 8 just seemed selfish.

As my boys time with sports of rapidly coming to an end I've been more intent on making this happen. I showed my wife paint schemes, seating arrangements, asked her opinion on pretty much anything that would affect her experience should I every get her back in a small aircraft. (Hey opinion is that the 747 is nice, but anything smaller flies "bumpy", including a 737). Finally she hit me with it. "Honestly, I'm not really interested in flying around in your little airplane". There it was.

I pick up my 8 tail kit later this month. I'm shopping for tools. You're all a bunch of crack dealers. <g>

If you know who has that 6 or 7 with a high end paint job, blue and silver with a fading checkered flag down the length of it, it's his fault. Thank him for me.

Sun N Fun 2019 - Full Trip Writeup ...bullojm1 RV-7

It's the kickoff to the 2019 big fly ins - SUN N FUN! On my way home from last years SNF, I decided I was not going to make the long EARLY run from Maryland the Florida in the same day if weather permitted. It's a super early wakeup (4am) and a very long day of flying. So this year, on my 4th consecutive SNF, I decided to work half of a day, fly 4 hours, then make the quick hop to Lakeland the next day.

Fast forward a year and holy cow...the weather gods Mostly agreed with my perfect plan...except for the winds. When I was at work, winds were blowing a gale - 70 degree crosswind, 23G38 at my homebase. Screw it, I was going to head out to the airport and see what it really was. 50 degree crosswind, 20G27....LETS GO TO SNF!!!!  continue


F-741B Tunnel cover size

Q: I've seen mentioned a few times that people have had to squeeze the z-brackets inboard in order to line up with the dimensions of the top plate. Seems like a fair amount of force needed to get them together.  Is there a reason this is the case and that's why Van's doesn't supply a wider piece?   I'm thinking of making a new one and take any stress out of this assembly.

A: (Draker) I just finished this part and don't recall squeezing that much to get it to initially fit. After everything was drilled and riveted, it fit well.

I did end up with quite a bit of "overhang" on the aft side. If I drilled it according to the plans the aft-most holes would have been too close to the aft ends of the z brackets. Instead I clecoed everything together, made sure I was happy with the fit, then drilled in a way that satisfied edge distance requirements.

I also ended up filing away a lot of that overhang in order to fit against the flap actuator brackets:

Dennis writes in:

First flight of CGRVU was May 15, 2017 after 7 years of construction. All went well with no snags and performance of the airframe and engine combination was gratifying and very grin-worthy. Engine is IO-360 A1A from a Mooney and overhauled by Dave From Aviation in Red Deer. Prop is Whirlwind 200RV and pulls RVU along at advertised book speeds. Skyview Touch occupies most of the panel space and controls the Dynon 2 axis autopilot. Paint is from UpperValley Aviation in Chiliwack BC. Thanks to Chris Droege from Idaho for an excellent training program that gave me the confidence to do 1st flight. Thanks to Van’s for a great product that provides a very high “smile per mile” ratio.

Non-RV Life Lesson - Don't Put the New Bottle of Tide on the Dryer!

I did, and in the middle of evening TV time we heard a thud, followed by a pop.  It vibrated off while drying stuff and landed ever so perfectly on its side...

...which was the perfect angle to blow off the top at a tad under the speed of light, which proceeded to shoot across our bedroom floor...trailing soap of course...stopping only when it got to the drapes....

....it took 30 minutes to clean up.  Used a squeegee from the shower and a large flexible cutting board, pouring a little at a time into a plastic bowl.

Status Report ...Josh T RV-10

Wings are just about done. Need to attach the fuel tanks and rivet the flaps together. Got the Fuse kit a littler earlier this time. With the wing kit I was without a project for a month and that just plain sucked. Lesson learned!

This box was quite the monster. The put the 1 long piece of angle in the box kind of sprung so it pushed against the side, and it ended up popping open the box side. Its bent a bit when you look at it down its length (8+ feet), but hoping thats not a big deal. Also wierd that there's only 1 big longeron, would think there would be two. We'll see what inventory says!


Some thoughts on mid-range RPM vibration… Piper J3 RV-12

I have had a flakey left EGT for a while and recently replaced the thermocouple sensor (Dynon EGT, Hose Clamp, 0.75-1.25”, Rotax SKU: #100405-001). I also did a fresh carb sync with a digital CARBMATE and got very good sync at both idle and just-off-idle. Unit works a charm.

My engine now runs smooth at idle and very smooth at 5500 RPM cruise. This is confirmed with the EGT’s. At idle and at 5500 RPM there is less than 10F difference in the EGT’s so both left and right cylinder banks are producing equal power.

The mid-range (3000-4000 RPM) has a vibration, and I believe uneven power L-R, is the cause. I have nearly a 100F difference between the EGT’s in mid-range RPM.

So, my thoughts:

• Idle and just-off-idle are easy to set using CARBMATE. The sync looks very repeatable and precise.
• 5500 cruise RPM is in good sync because both carbs are nearly wide-open throat and running on high speed main jet.
• Mid-range sync is a crapshoot. It’s easy to set cable-pulls to match at low end and high end is pretty much automatic. Mid-range probably has several factors that contribute to miss-match most of which are not controllable. Just musing here… perhaps airflow in the cowling can cause different ambient pressures for vacuum diaphragms that control carb throat opening. The good news is there isn’t much use for the mid-range, just don’t operate there. When on downwind leg, I start a steady throttle reduction to idle. The 912 engine has water-cooled cylinder heads so shock cooling is not a concern. Usually idle, or slightly off-idle, will bring me to the runway threshold, so mid-range is easily avoided.

  Hello.  Hope you had a nice weekend.  Some housekeeping duties up front here today. 
The tone and civility level in the forums hasn't been as light and fluffy as I require here of late, so I need to re-calibrate the knob a little.  VAF is, by design and business model, a tree of CIVILITY and POLITENESS in a forest of online hate, in-your-face insults and all around general douchebaggery.  Doing that here will get you kicked out.  By me.  Fast.  The posting rules are here if you've never read them.
  Wanna get super depressed super quick?  Try to make it through this whole article on the lives of FB moderators, then ponder on how wonderful an escape this place, and hobby, really is in today's world.  Keep it light, keep it nice.  VAF is about lifting up and motivating a dream, not tearing stuff down.
  Don't register if your only intent, stepping into my virtual living room the first time, is to pull the pin on a turd grenade.  Plenty of places online for that, and I get that some people are drawn to that stuff and think it's acceptable.  I'm not, and don't.  Respect the house rules, please.  Pretty please.
  Bad cop routine aside (I don't enjoy it, but I won't back down), hoping you got to fly this weekend.  On to the RV news over the weekend - there's a lot!


RV-8 Welcome Back To The Surface

I took some pictures of RVs landing and taking off last week, and while going through the take during thunderstorms over the weekend, noticed one right at the moment of touchdown.  Of note is the right main with some weight on it, and the left main still mostly circular with just a hint of burnt rubber vapor trailing behind it.  Beginning to spool up.  Isn't that cool? 



Exhaust leaks at the slip joint?! ...Jvon811

RV-4, O-320-E3D with mid 90's design Sky Dynamics Crossover exhaust...

The exhaust system has short stub pipes that bolt to the cylinder that's maybe 5-6" long and then slips into the next piece which starts the curve and crossover. I've started to get some blowback or leakage on the slip joint on the #2 Cylinder (Front Left). I can see discoloration on the #2 intake tube and plug wires along with the obvious staining on the pipe itself.

All bolts are tight holding the slip joints in compression but there is still a bit of wiggle where I can sometimes, but not always, rock the joint back and forth (maybe 2-3 degrees of movement) which I'm suspecting is the leak.

Anyone dealt with this before? Thanks in advance. I'll try and grab some pictures tomorrow if it will help.

Mods on Tailwheel - Fork - Springs ...DeeCee 57

Aim of these modifications were weight loss, practicability, looks and aerodynamics…

Weight: total weight change - 334g. Ain’t a lot, but could play favorably for the CG of some -4s.
Practicability: the original Van’s fork with its almost 90° angle to forward travel is an invitation to get stuck against any kind of curb with possible dire consequences. Rejected was the nice but massive Doug Bell product on the grounds of its weight, being too wide and requiring the use of countless washers, and elevating the tail of the aircraft. Keeping the tail low was a requirement for performance reason (use of very short grass runways) and looks. Welding a triangular section in front of the fork will hopefully prevent or alleviate having the tail stuck on some obstacle, weight increase 62g.


Milestone: First Mistake ...Tim Foster RV-10

I was admiring my new found countersinking skills when I realized I had just done drilled 24 of them on the wrong side of the battery bell-crank mount. Ugh. At least it’s a smaller part and it looks like I can reorder online at Vans. Hope the shipping isn’t too much. Lesson learned - read and reread directions at least 7 times. I’m guessing this won’t be the last time - part of the learning process.

My Panel Graphics Adventure...Hartstoc

When Searching VAF for panel labeling ideas I was intrigued by a suggestion to look into dry-transfer graphics. After comparing several options online, I settled on one company, https://imagetransfers.com , that seemed oriented toward professionalism and quality. It turned out to be a good choice, mainly thanks to Luann, a partner in the company, who was incredibly patient and generous with answers to my neophyte questions along the way. I’m quite happy with the final results but found myself struggling with a very steep learning curve, and the whole process took a couple of weeks of full time effort and concentration. Before describing the experience, here are a few shots of the final results, starting with the first full-dress rehearsal of the whole panel:

Greetings all,
  Well after lurking here for an eternity I have finally started a 7. I purchased an old kit from a friend to start with because it came with assorted tools and it was partly assembled...more on that later.   It took what seems like months to carve out a space in my garage {the family storage unit} to have a place to work. It still needs some upgrades but it has the basics for now. Im sure Ill be waiting on something someday and ill take care of the little things.
  Standard disclaimer, this log represents how I do things, not how YOU should do things. YOU have to decide that for yourself. My opinion is worth exactly what you pay for it. Fire away if you have suggestions, Im always open to constructive criticism.

Additional Pilot Program for Phase 1 testing- thoughts?...KatieB

Hey everyone! I'm still alive, mostly off the grid. I've been working on my PhD in Aviation (Aviation Safety) at Parks College (St. Louis University). One of my topics of interest for research is EAB Phase 1 flight testing safety, in particular, the Additional Pilot Program. I saw a thread from 2017 and 2018 on the subject, but thought I'd start a new one to gather your current thoughts on it.

How many of you have used it? Is it worthwhile? Are you aware of any accidents or incidents that have occurred with a Qualified Pilot on board (RV or other types)? What are your ideas on how to make it more effective?



Oh snap!

Rest In Peace, my 0.311" reamer! That got my heart going when this thing loudly snapped in half. This unfortunate tool met its end while reaming the -7A gear mount holes for the main gear legs. Thanks to great luck, it did not damage the workpiece while breaking. I've learned here that when a tool breaks it's usually not a bad tool but bad technique. Anyone have any tips for properly and safely using these very large reamers? I would like to not repeat this one.

Why'd the Blue Knob Stop Working?...seen at Monk's.

Moving the blue knob did nothing.  Plane brought to Richmond Aircraft Service (card) the other day at my home field (52F).  Governor?  Checks out.  Linkages?  Checks out.  Compressed air move prop?  Yes. 

Pull the prop. 

Crankshaft plug?  Oh....yeah, that would explain things.  It came unseated.


Monk has a tool that he either made or helped make (can't remember - it was decades ago) just for this purpose.  Helps apply equal force over the entire plug.


Aircraft had hundreds of trouble free hours on it.  It just chose this particular moment after takeoff to unseat.  Pilot pulled the prop knob back after takeoff as usual and observed no change in RPM.  Landed and the investigation began...


New plug currently being installed and things being buttoned back up.  Good find, Monk Man! 

Food for thought if you're troubleshooting someday...


SnF PIREP ...John Young RV-12

I have been to Sun 'N Fun about 15 times. Usually 1 or 2 days and I always stayed in motels.

This year I flew in on Tuesday, and yes I did get to enjoy Lake Parker because of a Bonanza with gear problems, and parked my RV-12 in the Homebuilt Camping. I tied down the aircraft, pitched my tent, put my stuff in the tent, and then went off to buy my wristband, etc. and headed to the main part of the show. It was about 5:30 p.m. so I decided to have dinner and a beer and the went back to the Homebuilt Camping area. I was in for a surprise. Since I had never camped, I thought you parked your airplane, pitched your tent, and you were on your own.

When I arrived back at Homebuilt Camping, I saw the big tent and all the people in it. I went over and went in and learned that they have food. I had already eaten but I sat down, introduced myself to some people, and began a wonderful evening of talking about airplanes, etc. About 11:00 p.m. I finally went to my tent and to sleep.

The rest of the week I had breakfast and dinner at the Homebuilt Camping. Almost every night I stayed up until 11:00 p.m. visiting, etc.

On Sunday morning I took my tent down, got the airplane ready, and flew home.

This year was my best experience at Sun 'N Fun. The main reason was because of the great experience at Homebuilt Camping. Heidi, the chairman, and all of her volunteers did a wonderful job. Everyone who was there owes them a huge thank you. The other people who were camping there were great, fun to talk to, and I learned many things.

The other reason it was the best experience is because I had 4 full days at the show. I have always been rushed before but this time I took 1 day just for forums. I did and saw everything I wanted to this year which is also a first for me. Always before I left saying I wish I would have had time to do ??????.

Homebuilt Camping was a good distance from the main show area. Most of the time I rode a tram in the morning, and stayed until dinner time, and then rode a tram back. I was fortunate I didn't have to wait long.

But this was my best Sun 'N Fun and I will definitely be back next year and will be camping again.


RV-10 Status Report ...Brantel

Now riveting the tail cone together and I have ordered my slow build wing kit on 4/3/2019. Should be here before the end of June.


Introduction - RV curious, and looking for local experts in Northern Arizona

Greetings all
I have just recently joined this forum in an attempt to find out more about the RV world.
I think I am most drawn to the RV 8/8A. (Mainly because of tandem seating and aerobatic capability).

I currently drive an "18 wheeler with wings" for a living (B747-8), and it's been way too long since I have enjoyed the passion for aviation that brought me to this career. It's time to rectify that!

To be completely up front - I am not an aspiring builder. I would enjoy learning to tinker with, and work on the aircraft, but I am just not cut out for the commitment that building requires.

I looked at RV's at Oshkosh last year and have had the pleasure of chatting briefly with Ron Schreck by phone. Obviously I have heard nothing but good things about RV's!

As I try to learn as much as possible about the world of Amateur/home built aircraft, it would be wonderful to try to connect with some owners who are local to me that would be willing to share their experience and insights.
I am in Prescott Az (KPRC), and I would be extremely grateful to hear from anyone in the area who would be open to assisting a curious newbie.

While it may be obvious, there is one issue that I can't stop nagging at me. How do I get past the amateur built vs certified peace of mind/quality concern?
Reading these forums, I know there are several folk who can assist with a good pre-buy inspection, but I am also aware of how many variations to design, construction and materials etc are out there.
While I know that no-one goes out to build a sub-standard aircraft, its the unknown and unforeseen consequences of a builder decision that I am concerned about coming back to bite me.
Anyone else work through this?

Thank you for taking the time to read this, and I look forward to learning more, and who knows - possibly becoming the next vociferous supporter of the RV.

F-710/F-779/F-786C  ...Aero_Octaveus RV-7A

Hi All, I am currently fitting up my aft fuse and experiencing the insanity of how tight and difficult everything is. I just about to start drilling and I have a question with how the lowest J-stiffener F-786C mats to the assembly.

If I have the nesting of the parts correct (F-710 bulkhead sits above F-779 bottom tail skin, which sits on top of F-778 bottom aft skin and the F-773 side skins). There is then a 0.040" gap where the lowest J-stiffener transitions from the F-773 side skin, to the F-779 bottom tail skin.

My question is do I just drill and rivet the J-stiffener leaving a small ripple at that location? Or did anyone put a joggle in the j-stiffner?

RV in the Morning Sunshine ...vid

Happened to be on the ramp with the iPhone when an -8 launched for a short flight at my home field.  If you have the monitor space and speakers, turn it up to 11 and enjoy.  I never get tired of that sound, and the 000000kt conditions Tuesday morning here made it that much better.  Pretty much the whole gang showed and RVated, if for just a bit, then it was back to the business of life.  But we sure felt better.... 


Slick Magneto Issue

I am having an issue with my Slick magneto on the right side of the engine. I start my plane with the left mag which has the impulse coupler on it. After I start the plane and have both magnetos turned on - if I turn off the left mag the engine dies which tells me the right magneto isn't sparking. I thought I had an issue with the wiring but today I disconnected the p-lead and ground wires off the right magneto to make it always hot and started the plane with the left mag. When I turned off the left magneto the engine died. When this issue originally started I pulled the right mag off and checked the spark off plug number 1 with a paperclip and it would show spark. I put the timing pin in the left rotation hole on the right mag and after setting the flywheel to BTDC reinstalled the mag timing it with the buzz/light box. Would an issue with the cap and wires cause it to not work? Is this a timing issue? I pretty much eliminated the wiring to the switch to be the issue. The plane starts right up on the left magneto. The plane has been sitting for months while I try to get this corrected/sorted (my current job situation doesn't allow much time to make it out to the airport).


Finally coming together! ...Zazoos

Just wanted to share my excitement. My RV 6 project received it registration in the mail today. N86TF is official!

Going to try and work 86 into the tail paint scheme related to the meaning that 86 represents. (I'm out of here, 86'ing this place, etc).

Rented hangar space last week and moved the wings to the airport this weekend. Just finished installing the panel. (I will post a write up and pictures on labeling the panel using a Cricut soon)

Pretty good Monday so far!


Brakes weak

I have an RV-9A with Cleveland brakes. Both linings and rotors were new 25 hours ago when I purchased the aircraft.

The pedals are firm (no air in lines) but the brakes are ineffective. Hardly can hold aircraft at full power, and don’t seem capable of locking the wheel on landing (this may be a good thing).

I thought they would ‘break-in’ , but not there yet.

Any suggestions? Is this common on RVS? Are the linings maybe glazed?

Long time lurker. New member. ...63scrounger

"Greetings everyone! I have been a long time lurker on this forum. My father has been a long time builder of an RV-6A slider. He has grown too old to finish the project and has passed it on to me to finish. ........ The project is very well along. The sheet metal has to be 95% done. All that I see remaining is the fuse bottom skins and the turtle deck. Both wings, fuselage and all control surfaces appear to be 100%. I have the wings in a cradle in my garage. The fuse is sitting right side up on a piece of soft 1" polystyrene foam on top of a 6' folding plastic table. I have had this thing for a few years now. I have overcome some challenges to my health and it's time now to get building on this thing! I need to find a starting point. I was going to go through the plans and instructions and compare that to my dad's builders log as a sort of inspection process. Could someone help me out by helping me understand if I need to make a build table and get it flipped back over? Or is it past that stage? Also the bulk heads for the turtle deck area are flopping around and I have no clue as to how those get stabilized and match drilled to the turtle deck skin. That is enough embarrassing dumb questions for one day..
I'm just grateful to be here. "

Charity Cap Sighting ...Plummit

Kansas.  No not the state, the rock band.

fmi: About the caps


Striving for A Consistent Force Required for Flaps

I have manual flaps on my RV-6, and I prefer it that way. When landing, if the winds aren’t gusting, I have a technique of raising the flaps right as the mains touch. This reduces my ground roll considerably in certain conditions, making a turn off at my exit much more likely when landing on 35.

Recently I noticed some spots for custom V speeds in my G3X software, in addition to the normal ones you’d expect. In an effort to get the force required to pull flaps each time the same, I entered two speeds: FLP1 and FLP2.


I’ve found the force required to pull full flaps at higher speeds, even through you’re well in the white stripe to be a LOT. Slowing down ten knots makes it much easier. Slowing down even more makes it hardly any work at all. I would guess that some people with electric flaps aren’t aware of just how much force is required at 87kts verses 74kts - how hard some parts might be straining.

I’m finding it fun to play around with. I pull FLP1 and FLP2 at the indexed values (pic below), then tweek the value a little on the ground. 1 knot here. 1 knot there.


I’m getting it dialed in a little better and have been enjoying easier, much more consistent flap pulls.

How I Learned to Stop Worrying and Love the Descending Curve

Ground track image from a short .2 a few days back showing the RV coming up initial (top to bottom straight line at left).  The dance starts around midfield on downwind (bottom right corner), followed by an always-turning, continuously-slowing, staying inside FM1171, flaps in there somewhere, prop going in, backing off the power to the backfire rat-a-tat-tat...then some back in, scan the runway for FOD and/or dump trucks, back to the AOA and speeds, a little trim bump, wiggle the feet and ass to get the blood going, pump the brakes on final to see if a foot goes to the floor, game face ON, over the literal fence on speed and in the energy state you strive for every time but don't always get.  Slightly tail low wheel landing on the spot you wanted, at the vertical rate you were shooting for.  3D French curve.  Mental gyros recalibrated for a day or so.  A little smile acknowledging just how good $8 of avgas makes me feel.


Writing the train wreck of a paragraph above made me smile, too - I wrote it anyway.  It's misty/foggy/OVC outside and nobody is flying.  While typing I got to relive the moment.

RVs equal sign happy face.


Status: Jcarne...with bonus drill through fingernail pic!

Well after bending the canopy frame to satisfaction I figured I mind as well go back and finish up the firewall. I installed the hinges on the lower half for the cowl. All that is left to do at this point with the firewall modification is to tape the seams with aluminum tape and throw in some of the magic goop (3M Fire Barrier Sealant 2000+) around the perimeter where the hinges are.

Over all I am SUPER pleased with how this came out. There are no noticeable wrinkles, only slight distortion of light (worse in the picture than in real life even). If you want to go with fire protection that looks sweet as well I think this is the way to go.

Canopy Frame Update:
Here are some pics of my canopy frame after bending. If anyone sees any problems or areas that need adjusted please please post or PM me. The only thing I haven't done yet is bring things in about 1/2" to account for canopy spread.


ADSB GPS for IFR flight

Maybe this has been discussed here before, but I don't recall reading anything about it, but I'm wondering if the new WAAS GPS units being sold by Dynon and UAvionics and such for ADSB can be used for legal IFR navigation?

I'm guessing that the answer is no, because they are not a part of a "certified" GPS "navigator", but it seems to me that if they are accurate enough for ADSB that maybe they are for IFR. No? Again, probably a different certification standard but I'm just wondering.

I also understand that the moving map and control function of any of the EFIS systems (other than the certified Dynon and Garmin units) are also not certified for IFR use, but hey? Just curious.


Green Fluid dripping inside cowling

I recently took my cowling off to work on my engine control cables and immediately noticed some green fluid dripping from the sniffle valve onto the lower cowling. Any ideas what it is and how to deal with it?

- Fuel dye

- BTW, it is good practice to have a drain hose/line connected to the valve so that excess fuel that drains out goes overboard instead of laying in the bottom of your cowl.


Part# help please ...7/7A

I am not near my project/plans and I need to order a couple replacement parts that I cannot seem to locate in the new/improved Vans store. I may just make them when back but if they are cheap enough I can order/pick them up.

I am looking for the angle that rivets to the fuse that holds the vent brackets- found this pic on a build log.

If anyone has it I'd greatly appreciate it.

- F-793 L&R Make from AA3-032 x 3/4 x 3/4

- Is a make-from part. Make from AA3- 032-3/4 X 3/4.

- Seems like I made them from wider stock because the edge distance was short but it might have just been cut longer. Slept since then. Bottom line, measure the distance accross the four side skin rivets and add edge allowance.


RV-10 HS-1016 Dinged

So since Van's Support staff is away at Sun-n-Fun, I turn to y'all.

RV-10, page 8-10, Step 2. The rivet gun jumped a bit while riveting one of the corner rivets attaching the HS-1016 Stringer Web to the HS-1014 and -1015 Stringers. Some slight deformation, no actual cracks or creases. Pictures below...

I need to know if this is a critical component or is this superficial, cosmetic damage and can build on?

- Inspect the dents carefully for cracks, if none then give it a quick whizz over with a scotchbrite wheel in your die grinder to soften any hard edges only, prime and carry on. Have a good look at what that dark line is just at the top edge of the rivet head - a paint chip or something more serious? Don't replace the rivet it is serviceable and trying to change it out may give a worse result.

- Looks like it’s probably fine, but definitely check for cracks like stated above. You may also want to check to make sure those rivets are set properly. Pictures may be at strange angles but the “shop” head on that rivet doesn’t look right.

- Are you using the correct size set in your rivet gun? Looking at that mark on the factory head to the left it almost looks like you are using a -3 set instead of a -4. That would explain it wanting to jump off the head as well.
It may be camera trickery but the dinged rivet shop head looks crooked along with the topmost rivet on the right side of your first pic.

  Spent most of Thursday working a side job to supplement the fam income during dem college years (the view), and while doing that explored the Pulse Ox Sensor feature of the D2 Delta PX watch Garmin is letting me play with for a couple months.  It does a lot of stuff as you might expect, but I REALLY like that you don't have to touch it when logging time. You just go fly. It wakes up in a 200'/min climb greater than 30kts. When you land it stops logging on it's own, then it syncs with GP while you're taxiing in.  Nerds of the world unite, as they say.  The times we live in, amiright?  Coupla grabs below from when I got home.

Final Update (Nose Wheel Damage) ...Flying Canuck

Probably the last update I'll put in here. I'm just back from another flight that went exceptionally well. Between this thread, the many PMs I received and a very good conversation with Ralph the other night, I've managed to get on track with landing this amazing airplane. Lots more practice ahead, but the method is working great so far. Here is my "works for me" landing process.

If in the pattern, pull the power back on the climb to keep from jumping to 110 KT at altitude. Get downwind established at 85-90 KT, TRIM to keep that speed and stay level. This is about 18" MP for my plane. First bump of flaps (5 degrees) after abeam numbers, let it bring the speed back to 85 if necessary.

Turn base, add 2nd notch flaps in the turn, power back to 12", pitch for 75 KT and when there, TRIM to maintain the approach hands off.

Turn final, all of the rest of the flaps in the turn. Pitch for 65 KT and when there TRIM to maintain the approach hands off. Here I can play with the power a bit to fine tune the descent rate, don't need to do much. It flies in pointing to the ground (uncomfortably even).

Over the runway, doing 65 KT, once 6' AGL, flair to LEVEL. Speed will bleed off slowly as it settles down gently. Tonight I was flairing at 60-62 KT and it was gentle. As the mains touch, add enough back pressure to keep the nose wheel off as long as you can, maintain centerline with the rudder while it's still effective.

My corrections really come down to 4 things.
- Intentionally get my speeds down, earlier, lower and stable
- confidently point it at the runway, don't rush to flair, and use small and gentle stick adjustments
- discipline to keep the procedures tight every time

Lots more practice ahead - I've only got 5 landings in during this rehab stint - but they are the 5 best landings I've had in the plane. While I don't doubt that the plane can be landed well at higher speeds by a more skilled pilot, it REALLY likes landing close to 60 KT. The side benefit is that I don't have any trouble sharing the pattern/circuit with 172s, had a 152 up with me tonight and there was no problem.

Thanks to everyone who pitched in on this thread. I hope it can be as helpful to others here as it has been to me.

Ignition Noise ...jump4way

I'm looking for some ideas to squash an ignition noise issue I'm having. I'm able to isolate the noise by shutting off one ignition and the noise goes away. The noise is a steady tick tick tick noise that has an increase in cadence as rpm increases. The oddity is that If I turn on my aux input battery powered bluetooth module, the noise goes away.

Things I've tried are:
1) ferrite cores on the power leads.
2) two types of noise filters with the offending ignition power wired through.
3) replaced spark plugs (using solid tipped automotive spark plugs)
4) Ohm tested each of the ignition leads for proper resistance. They all checked out to show appropriate resistance for the given length. I also slightly twisted and rotated the leads as I checked the ohm reading to see if anything seemed amiss.
5) crimped each of the spark plug connectors to ensure good contact.
6) put dielectric grease on each of the spark plug caps.
7) checked the spark plug gaps.

Any other ideas any0one might have?

Possible Solution to Why Wing Walk Didn't Stick ...MrNomad

Acrylic cleaner aka Prep Sol

The wing walk separation fault may be mine. Before I paint cars or airplanes, I always use a product known as Prep Sol, 3M Prep Solvent-70, to clean the surface.

To remove the old glue, I work with a credit card edge and lots of Prep Sol and it works nicely to remove the old residue. The paint remained intact (thank heaven).

The nice people at Flyboys suggested alcohol to clean the wing before applying the "walk" so I am wondering if the Prep Sol left a film that precluded adhesion. What works great with paint may NOT be what works great with the adhesive on the wing walk.

Once again, the folks at Flyboys offered a free replacement which serves as further testimony to their quality service. Blake claims that 95% of his customers have no issue but my walks have failed three times so I have to examine my procedures.

Comments welcome. What did u use before applying the "walk"?

Watch out for forward floor stiffener orientation ...Draker RV-7A

Here's a reminder to builders working on the forward fuselage. Don't make the mistake I did. This isn't really a gotcha because the plans are very clear:

When building the floor stiffeners, carefully examine drawing 23. For the inboard stiffeners, F-772B-R goes on the right side and F-772B-L goes on the left side. Makes sense. But for the outboard stiffeners, they must be reversed! F-772B-R outboard stiffener goes on the left side and F-772B-L outboard stiffener goes on the right side. If you aren't careful, it will not be obvious that you reversed them because the parts are similar and fit both ways. Later, you will go to fit the cover plates in the cabin and you will encounter this:

Angle Clip Interference ...mfleming RV-7

The aft top fuselage skin is ready to be riveted, but there is one skin rivet that's giving me problems.

This skin rivet is directly over the F- 707B angle clip shown on drawing 26, detail C and there is no way to buck this rivet..

In my frustration I compounded the problem by drilling out the skin rivet hole to ⅛" thinking I would install a Cherry rivet but the Cherry rivet hits the angle clip well before seating. I relived the angle clip some with jewelers files to see if that would give me room for the cherry rivet to seat but I stopped before relieving too much material.

The obvious solutions is to drill out the AN470AD4-5 rivets that hold the clip and rib to the F-707 bulkhead and reinstall after the skin rivet is bucked.

BUT, I'm afraid of screwing up the AN470AD4-5 when reinstalling. These were obviously originally installed without the top skin on from F-707 aft. The squeezer will not fit up there with skins on and one would have to use an offset rivet driver to buck the -4's and I have had mixed luck with those offsets....

Soooo....How important is this one little skin rivet? Not very I assume.

Any Ideas??


Testing fuel time with plain water ...romanov in Isreal

Fellow builders,

I have sealed the tanks and still dont have real fuel liquid close by.   Can I test the tanks with just water?  How accurate is that testing?  Is it possible that watter won't leak and 100LL later will.

- Yes, Water has a much higher surface tension than 100LL. While it might not leak with water it doesn't mean that it is still 100% leak proof. You would be much safer to do the final test with either properly regulated air or 100LL.  The initial test with Water should be fine to test for larger leaks. If there are any of descent size then water will still leak.

- Without pressure, solvents, such as gasoline, can easily weep through spaces that water cannot, due to the lower surface tension.


Run up saves the day! ...jhk770

(I own a RV7A with an IO-360 with dual electronic ignition with auto spark plugs)

Here is a quick story that I thought was important to share and to emphasize how important run-ups are even though 99% of the times they are un eventful.

My wife and I flew down to SC to visit friends for the weekend. We had a great flight down and our RV7A performed great. After a few day visit, we departed KAND after a thorough preflight and uneventful Run-up. We decided to stop at Lake Norman (14A) to check out the area and grab some lunch. This time my run up detected a very bad ignition issue. I taxied back, uncowled the engine and searched for the issue checking the connections to the coil and then spark plugs. When I got to the left side of the engine, the lower spark plug wire was just dangling!!! I was shocked. The spark plug "cap" had fallen off which led to the spark plug wire to come off. During annual I always make sure that I tighten these 'Caps", but never in a million years would I expect one to come off. Luckily I had spare plugs in my tool kit and was able to replace the "cap" and be on out way home to NJ without any issues. I'm disappointed in myself because I always try scanning my CHT/EGT's but I never saw any indications of poor ignition to indicate a problem during the flight.

I'm so thankful I was trained well to use check lists and I never cut corners and skip Run-ups!!

My question is, has this happened to anybody else and do you think locktite on the threads would help prevent this from happening or is there another solution.

RV-8 Prop Controller Issues ...pjmRV8

I have an RV-8 with O-360 A1A set up with a Hartzel CS prop. The prop controller teleflex goes through the firewall and makes an aggressive "90" to the prop governor on the rear of the engine.

Any help would be appreciated.

RV9 and CQ1 go to aerobatics school ...scard

Tanya and I had been talking about doing some proper aerobatics training for quite some time. We're always noodling opportunities to advance basic airmanship skills and this was a big one on our list. There are a lot of ways to skin this cat, but how did WE want to do it?

Last week, we loaded up the 12yr old RV9A with over 2000hrs on it and pointed the magic carpet east toward Alabama. The weather was perfect, and there was little to do but watch the miles go by. Before long, we rolled out on a beautiful quiet grass strip in the hills just east of Ashville. We taxied right into the hangar where the RV would sit for the next few days.

Some Thoughts on Tires & Brakes

I fly from a private grass strip in northern Ohio. Needless to say, not much flying in the winter months. So, the spring ritual is to look over the machine really good while I wait for the ground to firm up. Even though I'm based on a grass strip, almost all my flying is from hard surface runways.

Brakes are as important as flight controls for airplanes with free-castering nosewheel. Loss of a brake pretty much means deviating from the runway and having a bad day. Original brakes were replaced at 80TT. Now my second set of linings is due for replacement at 415TT. I think the second set of linings lasted longer because the disc was conditioned by the first set of linings, at least that’s my theory. The brakes pulsate and it has bothered me from day one. The discs are soft steel and get scored-up something awful. I have decided to order new Matco discs and will have Master Chrome in Cleveland, OH hard chrome plate them before use. Master Chrome does hard chrome plating for Cleveland Wheel so I should a good result. The hard chrome surface should stay smooth and eliminate pulsation.

The original tires supplied by Vans lasted 200 hours. The outside edges got scalloped and worn to the thread. I installed Desser 500-5 6 PLY RTO Retread, Elite Premium 2 Groove. At 415TT I’m very happy with these tires. The tread shape has substantially more rubber on the outside edges providing excellent wear. I’m going to rotate tires L-R because right side tire is showing slightly more edge wear. My plan is to run the tires until end of flying season and then I will disassemble the wheels and flip the tires so fresh edge is to the outside. It looks like I should be able to get 600 hours on these tires by remounting them on the wheels when the outside edge is sufficiently worn.


Any ideas?

Temperature probe fails

I’ve had problems with cht probes coincidentally with parking the plane outside for a week both at sun n fun last year, a Florida trip this year. In both cases after takeoff was surprised to find the readings quite low like 300 & erratic vs 1300ish. Received a tip from someone about heating up the base of the probe to near red hot three times between cooling off. It actually worked and brought the probe to accuracy after failing on its own to come back. I have drip loops at the probes so moisture would not run into the probe but somehow condensation must be entering.
Now recently my oil temp probe is erratic and wondering about trying that but hesitant since it normally doesn’t see temps that high as a torch might bring. Anyone with oil temp probe symptoms?

Just a test fit- but had to share ...Dan Reed

Picked it up from AFS Thursday and couldn't help but at least test fit it . Plenty to install behind the panel before it'll be secured, but wanted to see how it would look. It's set up to add an Avidyne GPS/NAV/COM at some point in the future.

In case anyone noticed the odd placement of the vent attachments, I had the modular panel (3 removable panels with radio stack) frame in before that I had to remove (will be in the classifieds at some point if anyone is interested).


1 Million Gallons of Oil on m'Belly! ...bkervaski

Fun times!

On Friday I went out to do my BFR and when I landed there was about a million gallons of oil on the belly of the airplane.

Took the cowling off, cleaned it all up.

Checked the oil, in reality only lost about 1/3qt.

The oil seemed to be collected around the oil cooler (right side bottom firewall on the 14), there was no signs of oil on the engine or near any of the connectors.

I couldn't find any leaks in the oil cooler. I took it off, pressure tested it (using only the "hold and blow" method and some soapy water). There were no signs of weeping near the elbows. No signs the oil cooler was the problem.

On the 14, the engine vent is pointing towards the oil cooler, dumping out over the exhaust.

The running theory at the field is that the vent line was clogged and came free dumping oil.

There was no indication in flight, no pressure drop or anything odd feeling/sounding.

My plan is to, while leaving the cowling off, taxi and run-ups to get the oil warm and see if any leaks show up.

Any suggestions or ideas? Thanks for any advice!

Oh .. and 1/3qt goes a LONG way

Condition Inspection Findings

It has been over 11 years since I first flew my RV-9.

In that time I have changed the engine (O-290 to O-360) due to a prop strike. Last year I found a crack on my engine mount and replaced that.

I started my Condition Inspection on Friday night and so far so good. Compression on all four Cylinders are normal. Last year #3 was low and I was using oil like crazy. Just recently I noticed my oil consumption was back to normal and sure enough, the sparkplugs were all dry and the compression was back to "normal".

Last year I replaced the O-ring on the gascolator and lubricated it with fuel lube, which I would always do. This year I removed the unused plug on the gascolator and it pulled right off.

After the gascolator was reinstalled I decided to "bleed" the fuel pressure line. Over the past year I would get low fuel pressure warnings on my EFIS and have replaced the wire, sensor, etc. and it would still come back on occasion but once the engine warmed up, it would go away and not come back on. Also, even though it would read 1 PSI in a full power climb, the engine never sagged, so I know it was getting plenty of fuel.

So, this morning I turned on the electric fuel pump and started loosing the plug on the "manifold" that holds the fuel pressure sensor until fuel started coming out. I was surprised at how long it took for fuel to come streaming out, once it first bubbled. With fuel leaking out, I tightened the plug back up and then turned off the fuel pump and master.

I will report back, once I'm flying again to let you know if this solved my low fuel pressure readings.

Now I know how Dorothy and Toto felt! ...ronschreck

The Summertime Kansas winds can really pack a wallop! I visited Salina for a few days last week and tied down on their massive ramp. When I was ready to depart the winds were 170 degrees at 38 knots, gusting to 45! Two large men held down the wings while I untied the ropes, loaded and started. I told the tower I was unable to taxi crosswind to runway 17 and would they mind if I took off from the ramp. "No problem, cleared for takeoff." The takeoff roll must have been all of 100 feet!

When I landed in Houston I unscrewed the tie down rings. Here's how they looked!

New guy and potential -10 builder!

Hello all,

New to the community although I’ve been researching airplanes to buy for years. I just can’t seem to justify spending a couple hundred grand on a certified aircraft that will be a project and to some extent “unknown” since a rod could be thrown or a case cracked at any time putting me out 50k for an engine swap. With that said, I think I’ve settled on an RV-10 for my family of 4 (two babies). I guess my concerns are how long the project will take to build and really how much experience or inclination you need to have as a builder. While I got a degree in aerospace engineering many years ago, I’m basically next to useless with my hands in terms of home or car repair, but I’m smart enough to learn when I need to. If things go my way and I get the orders I want next (in the Navy), then I’ll be set to buy the first (empennage) kit and tools/prep equipment this summer. If my wife moves ahead of me to get settled, I’m hoping to have at least a few months where I’ll be able to put in 2-4 hours a day of work into the kit. If I can knock out the empennage kit in that time (300-400 hours), I’m hoping the QB fuse/wing kits will really accelerate the project at my next stop. Is it realistic to have a -10 ready to start within 3 years if I can knock out 300-400 hours of work on the empennage kit in a few months and then QB kits after that? I am also all ears on recommendations, advice, and tips for a new builder! I really like learning from others’ mistakes.

EDIT: are there any RV-10 owners willing to indulge a ride in San Antonio or New Orleans?

Thanks all for the input on my ramblings!

A Virtual Tour of E-mag ...and UFOs.

Thursday while updating the DB's on my G3X screens, the opportunity to go with Monkey over to Azle, TX to pick up some P-mags for two planes in his shop (one for Bugsy I think) popped up.  I'd never been out to the E-Mag shop so was excited to get to finally visit it.  (35) or so pics at this link, many of them with captions.  THANK YOU Tom and Trent for giving me a tour.  Brad mentioned they are at SnF in booth C-098 if you want to see and hold some of the product (Van's will be at NE-012 and NE-013).

The very first P-mag.  The prototype (15 years old).

My two P-mags have been merrily purring along for many, many years and hundreds and hundreds of hours.  Someone asked me once about writing a review, and I couldn't think of anything longer than one sentence.  "I turn the key and it starts right up, and it always runs smooth."

The trip out and back also gave us a chance to drive through Aurora, TX of UFO incident fame.  You know I'm on that like a duck on a June bug.

Tri-Level Tournament Trip Write-up ...rph142

I always consider the Indian Wells pro tennis tournament the unofficial start of my rec tennis season. This year would be unique in that my wife along with her team won the fall Norcal Tri Level tourney and was invited to play and the national tournament alongside the pros with the other winners from across the country. This of course gave me a great excuse to put hours on my 3B.

Here's my machine, ready willing and able, with a fresh oil change and glossy coat of wax.  ...


Roll your own Mag cover ...AX-O

I am getting ready to build a motor and wanted to step up in class during the portions of the build where catastrophic FOD inside the motor could occur.

Specifically the portion where I put a piece of cardboard where the mags and other accessories go.

So since I have been designing things on Solidworks for the plane, figured I could give this a try. The studs on the case are too long. I will fix that later. This is just a trial fit. I rounded the edges on the cover so I could easily grab it with my fingers to remove it. I also re-enforce the area with a flange in case it got smacked, it did not fall apart. The part is strong like bull.

Throttle and Mixture Cable Routing ...Lynnb RV-10

So I'm using Van's Throttle Quad and Standard cables, I went to route them tonight to check the lengths were good, which they are, but the clearance around the engine for the Throttle cable is really tight. I ran the mixture cable under the engine mount and I think it will work, just wondering how others have routed theirs and am I missing anything. (see pics.)

  So I'm warming up the engine for a little .1 or .2 to get the juices going before work, and I hear a friend inbound on the radio.  "A little choppy."  An understatement.  I launch and almost immediately the wiggles and bangs start in - don't climb out of it until about 2,500', and by that time my head already hurts.  Why am I spending nearly a dollar a minute to do this?  I turned around and land after about .2, and walk up to my friend at his hangar and say, 'a little choppy huh?' <g>.
  Walk over to Monk's and he says, 'I think your site is down.'  Huh?  I pull out my phone and there are 20(ish) emails, vmails and texts saying same.  I should look into this when my head stops ringing.
  Between calls with the ISP and quality laptop time, we went to Whataburger for lunch, and Buc-ee's next to it for car gas.  There is a NASCAR race this weekend here, and this was at the pump next to us.  These folks don't mess around.

(click to enlarge)

  Back to the equipment outage, bottom line is the box my virtual machine (VM) is on, along with a few more clients, got a case of the vapors this a.m. and decided to go on strike.  A reboot of the VM got the site up, but there were a couple of corrupted tables in the grab bag that makes up the forums, and the box was suspect.  The easiest way to repair this is to restore from backup to the last known good instance (last night) on a new box.  These things take time.   Restores always seem to take longer than you think they will.  It took all day but it's done...
  So, the turd sandwich in all this is if you posted something between around 9am and 4pm on Wednesday, my apologies.  It's gone.  It looks like most of the posts were classifieds at first glance.
  Once the restored site was online on the new box, and the ISP cut it over, I smurfed on over to the mothership and grabbed some first flight news (below) to help build a quick and dirty edition for Thursday.  Again, my apologies.  Technology happens - occasionally not like you're expecting.  If memory serves, this is the first full blown restore in 11+ years.
  Moved over a million posts over to a new box, ran a she-ite load of database repair utilities, changed some internals to point to new equipment, adjusted backup routines to get the new box tonight.  It's been a long day with more technology than I care for.  Things seem stable for now, but we're talking with the brains about more robust hardware with newer OS's.  All good things.
  If you haven't listened to the latest
VAFcast, it's 42 minutes long.  Axel was a great guy to interview!  Maybe that'll help some if you got withdrawals.  ;^)

Classic Aero Interior Lead Times

Hi Everyone,

I just wanted to put out a heads up to those planning to place an order in the near future. Due to the recent release of side panels for the RV-14, the volume of orders on our schedule is about double the normal amount. Currently our ship dates have been pushed out to around the end of August.

We expect this to be a temporary situation. Historically our lead time has ranged from about 8-12 weeks (usually depending on the time of year). We will be working to get back to that. Over the past 12 months, we have invested significantly in new epuipment to produce our own metal parts in house. This was in aniticipation of the RV-14 side panels. We expect this to give us greater control over scheduling, and cost.

If you need your interior by this fall, you will need to place an order pretty soon. On the other hand, if you won't need your interior until next spring or later, it would be helpful if you could hold off until later this year so that we can take care of customers that will be ready to fly sooner.

I appreciate everyone's understanding so far as we've been working through this transition.

Best regards,
Luke Doughton

Traffic Jam During Superbloom ...AX-O

I guess I don't get originality points for taking my wife to see the flowers from the air but......

I was probably 20 miles out when I spotted the flowers, even in the haze they were bright. Once we got closer we noticed the traffic jams. Cars for miles and miles. My wife says "OMG look at the traffic jams, glad we are flying". I said "well you look all you want, I have to fly and deal with my traffic jam". It was craziness out there.

Status Report ...David Paule RV-3B

Now both the seat and the baggage floor are pilot-drilled.

After this, I removed these and drilled the substructure for the nut plate mounting screws. No photo on the holes, and the hardware is on order. I did remove the flat seat ribs and added the nutplates to these, as it was easier to do that then do them in place.

With both landing gear legs drilled to the engine mount, I located and pilot-drilled the U-403 brake mounting fitting to the axels. Then, Rick and I drilled its mounting hole. The drills used were, in order and in inches, 1/8, 3/16, 1/4, N and finally the .311 reamer. I forgot to get a photo, but there wasn’t anything especially noteworthy about the set-up. Rick made some aluminum vee-blocks, which did a fine job gripping the axle. The 1/8 bit was in the pilot hole, which was just deep enough to locate it. We eyeballed the bit for verticality, rotating the axle as needed, and then went ahead and drilled it.

The landing gear is all going back to storage as I won’t need it for a while. The reason all this took place now was merely because it was easy to align to the fuselage at this stage. I’ll all in favor of making things easy. Besides, it's so much easier to rotate the fuselage when the gear legs aren't on it.

I found several smallish parts that haven't been plated yet, like the brake flanges and rudder cable straps, and got those ready for plating. I'd better have a look in the crates to see if there's anything else, too.

-8A Cracked Canopy

Cruising along at 4500 ft. Saturday from Rostraver, PA (FWQ) to Bolivar, MO (M17) fat, dumb and happy. OAT 23 degrees; 163 kts TAS; no turbulence. Hear a loud bang, but no change in engine parameters or flying qualities. Landed at I23 (Fayette County, OH) to check things out. Discovered a 15 inch crack in the right side of the canopy about ten inches forward of the cross brace. Sikoflex install with not a single rivet in the canopy. Previously had and stopped drilled two 6-inch cracks on either side just forward of the cross brace so I felt further cracking was not going to occur. Have no idea what the specific causes were unless I inadvertently created stress points when clamping the canopy during initial fitting.

Want to attempt a repair before punting to a new install. Can anyone point me to the previous forum threads that offer the best repair advice?

And yes - that dull roar you may have heard early Sat morning was me repeatedly going through my curse word inventory.


Recent First Flights Reported on Mothership


Alcohol and Flying ...a travel story from Bill R.

In talking with some friends, we wanted to get together for a weekend away from home, without the kids, preferably someplace halfway between us.

We thought Rough River State Park would be good and one of the wives was making a reservation at a local B&B only to be told by the proprietor that there was nothing to do there and if we were looking to do something other than hang out at the B&B, we might look to go somewhere else.

Back to the charts to find a place that was not too far away.

After much studying over my last glass of bourbon my eyes fell upon Frankfort, KY (KKT). Frankfort happens to be the capital of Kentucky and smack dab in the middle of the Bourbon Trail.

With four planes and advance planning completed, the eight of us were ready to go and the wives were busy planning meals, distillery tours, etc.

Friday morning, March 22nd rolled around and there was snow and ice in the Cleveland, OH area but clear throughout the rest of the Southeastern US.

The RV that was to join us from Cleveland dropped their kids off at school and started driving south and would be late getting to FFT.

The V-tail Bonanza that was coming in from Atlanta had to work late and would be late getting to FFT.

The T-tail Lance that was supposed to come from Nashville texted and said they were in Florida and would be late getting to FFT.

Not RV But Too Cool Not to Spotlight



Broken Step - Pilot Side

During inspection I came across a crack in the pilot step. The crack shown in the picture is located on the front side of the step at the intersection of the horizontal step to the vertical portion that leads up to the fuselage. I ordered new steps from Vans and noticed that the welds in this area are very small. The picture was taken with the step being flexed in a vise.

Just providing this for others to see, the airplane has around 900 hours on it... - Jason

Milestone: IFR Checkride Passed ...Dave Ford RV-10

Today passed my ifr check ride in my 10. First rv10 the examiner had flown in, was impressed with what we get for the money vs. Cirrus, Columbia, even the high priced Cessnas he flies in. He does a lot of check rides for the local college here.

Had a slight glitch to overcome regarding partial panel, he’s used to g1000 or steam but not the experimental glass. Since I was able to duplicate on another screen primary instruments when covering up ai he thought that wasnt acceptable for acs standards . He learned something about IR.VII.D.R1 that ‘use of secondary flight displays when primary displays have failed’ allows a complete secondary efis to qualify as a true secondary backup.

Now looking forward to the 10 opening up more adventure.

A How To Guide for Wrecking Your Nose Wheel

As mentioned in my recent AOG thread (I'm all fixed up now thanks to VAF), I destroyed my nose wheel tire, tube and fairing on a hard landing a couple of days ago. Now that I've stopped shaking, ran through the experience in my head too many times, talked it through a few times and analyzed my data logs, I thought I'd recount what happened and what I found out. I apologize in advance, this is going to be a long post.

A little background, I'm a mid life crisis pilot and builder. Got my PPL 3 years ago, managed to build about 240 hours total time. Finished my RV-9A last summer and have 70 hours and 100 landings on it. The incident trip was a 3 day leg stretch to the Denver area, my first trip into the US and first multi day trip. The incident flight was from Billings, MT to Lethbridge, AB to clear customs. 2 hour trip, coming after my 2 hour initial leg out of Rapid City. This was my first flight into Lethbridge and it was the 5th unfamiliar airport of the trip.

My initial approach was to runway 23, 200' wide (first time for me) and I had a shifty quartering tailwind. In looking at the logs later, winds went from 126 at 7 at 500 AGL to 59 at 5 on the ground. On top of this I was fast, 87kt over the numbers. This was already a recipe for trouble. The approach ended in a well executed bounce to go around, no second hit and quick reaction to add in full power.

My second approach was to the same runway, a little better speed (78) but still too fast. This one bounced as well and I had go around power in within 2 seconds. FSS gave me runway 12 for my next pass, winds were a little better for it. This is 150' wide so the sight picture needs an adjustment.

My third approach was decent, still a little fast and ended with hard contact on the mains. I read that as a bounce and immediately put in the power. The incredulity of my situation was hitting hard and the nagging voice in my head started shouting that I'd forgotten how to land. FSS was treating me like an emergency now (so I found out later when I paid them a visit).

My fourth approach was the one that wrecked things. This is the "how to". One decision. I hit hard on the mains again and decided to override everything I knew and pushed the nose down to try and save it. The logs showed that I hit the mains with 1.5 g at a pitch of +1.3 and in 3/4 of a second hit the nose wheel at 2.4 g at a pitch of -5.4. I think I anticipated the bounce and had already pushed forward before the initial hit. This bucking landing hit happened again a couple of seconds later with 2.6 g on the nose and a 13 degree pitch change. If the first one didn't smash things, this one surely did. I finally decided to do what I should have done, pushed in the power and got out of there.

On that fourth climbout, FSS asked me if I would like to fly away for the airport for a few minutes to collect myself. It was just what I needed to hear and I did that, all the while talking through the landing process out loud. After about 6 minutes I requested a long final for 12, thinking that a long stable approach would give me the best outcome. Finally, 30 minutes after my first approach I managed to get the landing I so desperately needed. It wasn't pretty, still hard and I had a couple of nose oscillations after the mains stuck. I taxied in and declared my day done (we had planned the 1 hour flight home after clearing customs) before finding the damage that formally ended my day. In the end, the tube was punctured, the inside sides of the tire were delaminated, the axle bolt was slightly bent, the wheel pant had 3 large chunks blown out and the leg fairing was cracked with a couple of popped rivets. They closed the runway behind me as soon as I found the hole in the pant and they found the pieces.

I still need to wrap my head around my landings, my landing back home yesterday wasn't very good either. I am sure of a few things. Firstly, my wheel pants went on recently, I only had 3 landings on them before starting on this trip. The pants bought me 12 knots at cruise and the speed management is a whole new beast that I need to get a handle on before any further flight. Secondly, my hard hits/bounces are coming from failing to counteract/avoid sudden sink over the runway. Lastly, no matter how frustrated, angry, scared, tired, confused, anxious I get, NEVER try to save a bounce by pushing the nose forward.

If you made it this far, thanks for reading. This post is mostly for my own benefit as I work through this, but since I'm not the first or the last to experience this, I thought it was worth sharing and discussing. I'm going to take a short break from flying so I don't have recent memory haunting my decision making. Then I'm going up and spending a good hour entering and exiting slow flight at a safe altitude before getting some circuits in and relearning my landings and reclaiming my confidence.

I bought a GTX-345 and a Flightstream 210 at Oshkosh last year. I did the initial install in August of 2018. I replaced the existing GTX-327 with the GTX-345 and added the FS-210. I also replaced the audio panel, upgraded my TruTrak autopilot, and made some wiring changes to my AERA-660.

The initial installation went well but, after getting it up and running, I discovered a configuration problem that required some minor rewiring. The transponder was working well but I wasn't getting the proper data from the 430W to the autopilot or the EFIS. This is a big foot stomper! All the data format options are not available on every input or output of the 345! RS-232 1-3 have more options than the RS-232 4 port. And, you sometimes cannot configure the inputs and outputs of a single port separately. Good luck finding that in the documentation! I had established my initial wiring based on being able to configure some things in the 345 that weren't possible once I got it all hooked up.

I decided to fly with the less than optimal configuration for a few months for a couple of reasons. First, I dreaded pulling everything apart again and second, I thought I might learn more about what changes I should make when I went back in. That was a good decision.

Additionally, my RV-8 did not have an avionics access panel in the forward package compartment. I was determined to put one in before working on my avionics stack again. That was another, exceptionally good decision. So, a few days ago, I made the big cut and installed the access panel and boy did that make things easier. I'm not sure why anybody would every build an RV-8 without installing an access panel in the forward baggage compartment. I should have cut one before doing the initial installation of my ADSB equipment. SOOOOO much easier. I was able to access the 430W and GTX-345 plugs and rewire the necessary pins without pulling the panel.

When I bought the GTX-345 from Spruce, I also bought their harness. That was also a great decision. I made some significant modifications to the harness and added a lot of other wiring but the pre-made harness was a good start and well worth the cost. Just being able to see how Spruce manufactured their harness gave me a real leg up when I started making my own. Wiring the GTX-345 and GNS-430 isn't overly difficult but did require some techniques I hadn't used before. I'll just say this - get the right size pins, the right pin inserter/pullers, a good mechanical pin crimper, Raychem solder sleeves, and a really good soldering iron!

Configuring the various equipments was the hardest part. Finding accurate documentation on the Garmin equipment is frustrating. I emailed the G3X team and they put the latest and greatest manuals in my hands. That was essential as a lot of the stuff on the internet is outdated and incorrect. This is especially true when it comes to the settings / configuration pages of the 430 and the 345.

I'm very happy with the 345 and the 210. The 345 is a superb (though pricey) one box solution to the ADSB problem. The 210 allows my 660, iPad (Foreflight or Garmin Pilot), and the 430W to exchange flight plans and updates in real time. I also made a 232 connection between the 660 and my SL-40 that lets the 660 send the SL-40 frequencies for the selected airport automatically.

Cracked nose gear faring ...AviatorJ RV-10

23 hours into Phase 1 I was doing performance Takeoffs and landings today. I'm afraid I brought her down a little bit hard today on a 'short field' attempt. Taxi'd back and inspected my gear fairings and found this....

Fixing it is pretty easy. To prevent it from happening again (I will land hard again in the future). Should I put some more clearance on the radius's to accommodate smashing the front wheel? Or could this have been something else?

RV Stuck: Nose wheel in Lethbridge, AB ...if you can help.

Second to last leg on my US trip ended poorly. Lethbridge got the best of me and after 4 bad bounced landings, and I mean bad, finally got it on the ground. Apart from my nerves- which are going to take a while- all I’ve damaged is the nose wheel fairing, which is a total loss and a flat tire.

Anyone in the area with a tire, might just be the tube. Moral support would help too.

Just Starting out- looking for NH or MA RV builders

Hello all, first post. I have been lurking for many years and am finally getting to a point in my life where I may have the time and money to finally start flying. I have taken a couple of first flights over the last 20 years and also fly whenever a friend or friend of a friend invites me.

In any case, I am looking for "local" (MA or NH) RV builders so as to take a look at the work, ask some questions and maybe help if they want it.

Many thanks,

O-320 E2D Drama ...Sam I Am

I purchased my first plane, a 2003 Vans RV-9A, July 2018. I commute from Texas to Kansas weekly for work so have accumulated almost 200 hours since purchase. The plane had 525 TT when I bought it. The Lycoming was a rebuilt that was in storage for some time before the RV builder purchased it in 1999. Previous log books were not available but Lycoming estimated that it had been in use for 2,000 h when he purchased it. The engine was disassembled and reassembled by A&P with new gaskets and seals at time of the builders purchase and pistons, valves, seats, cam, lifters, etc all appeared new based on log book entry. Had a prebuy conducted and no issues were noted at purchase.

Almost immediately fuel burn went to 11 to 12 g/h and the engine would not run smoothly. Two mechanics later there were multiple fuel leaks found. Replaced the Van's fuel selector valve with Andair. Fixing the leaks brought the fuel use back to 7,5 to 8 g/h but the engine was not very smooth. Found the intake connector hose clamps were loose and tightened them up. Through trial and error determined that when the electric fuel pump was turned on, the engine would turn off! Only use electric fuel pump when priming. The primer was checked and not leaking fuel to the cylinders when not activated.

High CHTS climbing out has been a common issue (425F) until fall weather brought cooler ambient temps. The plane is equiped with and EIS 2000 with probes in the 1 and 4 cylinders. Baffling is in good shape and checked again last night with flash light for leaks. Started to notice that the mixture would be set at flight elevation then would get LOP after some time. The engine tried to quit several times at take off then did quit at 11,500 over the panhandle one day. I then replaced the carb with a rebuilt Marvel-Schebler MA-4SPA and a new lycoming mechanical fuel pump. Wow! The engine ran much smoother and fuel burn at 7 g/h. Thought I had it fixed....

Now that the weather is warming up, the CHT are skyrocketing. Yesterday I left TOP (880 msl, 60 degrees F). I taxied to the runway with the engine leaned, conducted my runup to 1,800 rpm after enrichening the mixture. The left mag was rough so ran the engine up and leaned to burn off the plugs. Next mag check spot on. As I lined up to take off, the CHT #4 was already 425 F and #1 was 415F. I took off with one eye on the sky and one on the EIS. I climbed very slowly, full rich, as the temps went to 485. When I reached 3,500 msl, the cylinders started to cool to less than 400 F as I continued to climb to 10,500 (32 degrees F). The temps settled in at 375 and 355 for the remainder of the flight. When I landed in Amarillo, the temps immediately went to 285 for roll to the hangar. This has been the condition for the last 3 flights. The previous flights did not entail having to burn off the plugs before take off.

I'm about to conduct an intake leak test but thinking that my scenerio doesn't quite fit a leak. I've read that the Lycoming SB 258 can be an issue so will pull the carb and check the intake through the sump for dead space. Any other ideas would be much appreciated.

While I have the podium, I would like to thank everyone for their time and knowledge on this forum. I'm a newly minted pilot with a new plane and would have walked away by now had it not been for this forum and peoples honest input. THANK YOU!!!!

RV Law of …

A stab at comedy. I’ll get the ball rolling with:

"RV Law of Clean Leading Edge Slash Dirty Belly"
If you just clean the leading edge of your wings after a flight, the longer a visitor stares at them the probability of them believing the belly is also clean approaches one.

Got one to offer up?

Flying Away from Tennessee ...Capt Sandy

When Roy and I started dating almost 15 years ago, I never expected that our flights to the coast for dinner or down the valley for lunch or hiking would turn into journeys across country. I never expected that I’d want to fly anywhere other than the Pacific Northwest. And I certainly never expected that we’d fly as far away as Tennessee - or that I would fall in love with the Smoky Mountains. I’m so happy for the Plane He Built.

Unexpected altitude change in RVs and the 737Max8 ...ClayR

Last evening, while enjoying glass-smooth air at about 4000' just after sunset, my RV9a unexpectedly pitched down hard. I had just reached over to pull a little cabin heat when it happened.

My first thought was I just hit a massive downdraft - something was pushing my nose down hard. I could pull back to counter it, but had to pull on the stick hard and it wasn't letting up. I pulled throttle back and it eased up a little. My second thought was "how could cabin heat cause this" when I didn't have an autopilot that might be affected by the changing pressure in the cabin.

Then, I tried pitch trim up (electric trim, with a switch on my panel just above the throttle) and it just as quickly corrected itself.... problem solved!

But, it certainly got my heart racing, and also thinking about how the pilots in the recent 737 Max8s that crashed must have felt as something 'external' was pushing their nose to the ground.

I certainly didn't think my right hand finger was pushing the trim button at the same time my left hand was pulling the cabin heat knob, but my right hand was resting on the throttle where it normally does, and I suppose it could have happened as I slightly leaned forward to pull that knob. I don't suspect a faulty Ray Allen switch, but I suppose that could have happened too.

I also took out my original ray-allen trim indicator on my panel when I installed my GRT efis, moving the trim indicator to the EFIS. However, the trim indicator isn't shown when I'm in PFD mode with a split screen with moving map, so I didn't know the trim had moved.

I checked the forums this morning and found several other threads describing similar incidents where people had bumped the trim buttons on their stick, or had malfunctioning switches. They described very similar symptoms as I saw...

The best suggestion I saw was to install a "Safety-Trim" which limits any press of the trim button to 3 seconds before you have to release and press it again. I'd like to hear from anyone who has installed one of these because it seems that the limit should be 1 or 2 seconds instead of three. I think it could happen again similarly with a 3 second press of the button unless I slow the trim motor down a lot. (which might actually be a good think to make it more sensitive to fine adjustments)

I also thought that perhaps installing a big red "TRIM" light on my panel would alert me whenever the trim motor is activated. That might get annoying though during regular use though and I'm not sure how to wire it.

My third thought is to see if I can program the EFIS to display an error when the trim reaches a certain point away from center. That would have helped me identify that the trim was out of normal range. Has anyone done this on a GRT EFIS?

At the VERY LEAST, I STRONGLY ENCOURAGE EVERYONE with electric trim to practice dealing with unexpected trim by establishing cruise speed at a decent altitude,press the trim button up or down for 4 or more seconds to see what it feels like! See how much back or forward pressure you need on the stick to counter it! I wish I would have done this when people talked about these issues before so I would have been prepared for it when it happened.

In any case, I'm sharing this to hopefully avoid others from experiencing the same thing, and to discuss the best possible options to keep it from happening again... or at least quickly identify the issue when it does.

Please, don't discuss manual vs. electric trim here... I have electric, and I'm not changing it now, although I might put manual in my next build.

Leaky Brake Fittings ...fbrewer

OK, so we have leaky fittings on the right side brakes.  We've tried tightening the plastic fittings without stripping the threads -- no dice. Still leaks.

Any other suggestions to my leaky brake fitting problems?

Don Orrick's Visor for his RV-10

My solution that I just completed during my condition inspection was to buy the RAM $68.00 visor from Aircraft Spruce and the SHORT Ram ball clamp connector. It is only 2.5'' -3 '' long. I then ground one end of the ball connector to the curvature of the round center bar using my removable co-pilot control stick that is the same sized material as a template. I then painted it and glued small pieces of rubber to the inside of the ground end to prevent scratching up the post and allow the clamp to grip the post tight.

By using the short ball mount modified to fit the post, the visor fits between the post and the edge of the door frame just right. the visor can be adjusted up and down the post depending on how high or low the sun is during flight. You can also swing it around to cover the co-pilot side of the windshield if needed. It can be easily removed by just loosening the ball clamp and set it in the back seat.

I also installed a ball mount above the pilot's door with a nutsert to mount the ball stud and utilize the same visor on the door by ordering another short ball clamp WITHOUT modifying it to fit on the ball mount and the visor ball. It works great and can cover the entire side window area for those early morning flights when the sun is pouring in the side window.
1 visor
2 ball clamps
1 ball stud for door
under $100
Test flew it and works great!

Old Geezer Update (his title) ...David-aviator life update


I've been member of this forum for a while and have enjoyed the comradeship over the years. There are lots of good people here sharing a passion for flying and RV airplanes.

I am still flying. And perhaps to the delight of some old instructors with whom I've had exchanges here, have finally gotten close to 3 pointing the RV-7.

The tail dragger experience came late in life to me, age 75, so it was some challenge in the beginning, glad I did not wreck the RV-8.

The 7 belongs to a friend who asked me to fly it once in a while after he had open heart surgery. The RV-8 I built at age 74 was sold to a friend about a year ago. Had this compulsion to down size, stop spending money, not knowing what was coming next after wife passed away. Flying the 7 has been a blessing, I still enjoy it.

But at this stage of life, question keeps popping up, when should one quit? Common sense says no one flies forever. And end up a statistic due to pilot ego because the envelope was inadvertently exceeded, like I can do this forever, makes no sense. Is somewhat of a dilemma making decision on this subject.

Beyond that, I've decided to get married again. I hate living alone, have reconnected with high school friend in Minnesota where I come from, will be moving back there this summer to be with her. She is widow and feels same about living alone. We go back long way to riding horses, milking cows on Minnesota farm 65 years ago as teenagers. It was not difficult getting reacquainted.

Anyway, just want to say Hi to forum, this place is great for what we are passionate about - Flying airplanes and in particular the RV's.

Crashing in the wilderness... some thoughts ...Paul_5r4

Sorry about the length of the post!

Hey fellow VAFers,

Because I feel this is an important post, I’ve been working on it for a few days.

A bit of history regarding this post. Recently I’ve watched several videos where regular people unexpectedly find themselves in situations that ended up potentially life threatening. After watching several of these videos, I’ve noticed there were some common denominators. One is in each case they’ve unintentionally found themselves in these situations and finally reached a point in their struggles way to early on that they have zero options left. As pilots we should be prepared, having at least thought about the what’s and hows after a successful forced landing. As pilots, we always need to have plan B and never have the thought of “there is nothing left I can do.”

Naturally as pilots we most often think of the aviation side of flying. I looked at my checklist and online at some others. That’s were the checklist ran out. They all do a fantastic job of getting everything configured to give us the best chance of survival in the event of that hopefully never to happen off airport landing…. Hmmmm, off airport landing. Almost makes it sound like something that’s routine. In the real world and in the heart of hearts of most pilots, I think we still call it a crash. I don’t know… maybe that’s politically incorrect now days. :-) Take note though that is where the checklist ends. I hadn’t given much thought regarding survival in the event of hours or days until help arrives. I did have a little survival kit but didn’t know how to use half the stuff in there. All of this left me thinking despite having the little kit, I didn’t have a survival plan, not even a little one.

Help!  Oil Pressure Loss when Cold and Hot ...rv969wf

Alan Judy's Van's RV-6 with a Lycoming IO-360A1B6 fuel injected engine, CS Hartzell Prob. Approximately 750SMOH. Almost everything inside this engine was NEW except the case and cylinders, cylinders were taken .010" over with New pistons etc. All machine work was done correctly and Yellow tagged, engine was blueprinted very precisely. All clearances within factory specs at overhaul and I did the assembly so I know this engine inside and out. SMOH this engine has always had around 45psi oil pressure +- 2-3 lbs at 190F degree oil temperature at idle 750rpm. In cruise it has always had around 75 lbs +- a 2-3 lbs at 2,450 RPM with oil at 190F degree. I have always been able to maintain my oil temperature plus or minus 5-8F degrees between winter and summer via a controllable oil door, the NEW Vernatherm at overhaul has never caused a problem. Engine has had Exxon Mobil Elite 20w-50 it's entire life after rings were seated. Oil and filter has always been changed around 25-30 hours. Oil samples have always been good and oil filter has always been very clean when cut apart and inspected. Engine is preheated in cooler months so I haven't had any cold starts, I live in the Oklahoma area in the USA. I average 90-120 hours per year and fly mostly cross country with a few short trip, at times I'll close the oil air inlet to the oil cooler get the oil up too 200-210F to boil off any moisture in the crankcase for a few minutes then lower to 190F range. Compression always around 76-79 over 80 at annual.

This is what happened on my last flight, on run up, my oil pressure was normal at the time. I took a 45 minute flight and shortly into the flight I noticed my oil pressure was only 52 lbs at 2,450 RPM, 190F oil, it has always been around 75 lbs +- a couple lbs SMOH at 190F oil temp. After landing my low oil pressure light came on, my low oil pressure sending unit is a separate unit than my oil pressure sending unit and it is set at 25lbs for the light to come on, I then looked at my oil pressure gauge and it was only showing 23 lbs at idle 750RPM, 190F oil. The first thing I did the next day was take the oil filter off and cut it apart to inspect, Tempest #AA48108-2, the filter media was VERY clean with no debris. I build automobile racing engines for a living and few airplane engines so I know what to look for. Oil level in the crankcase was showing 6 1/2 quarts at this time. I have always flown after an oil change with 7 qts total and when it gets down to 6 qts I add one quart, oil burn has always been about 1 qt in 9-12 hours with my steel Lycoming cylinders SMOH. My next step, I installed a New oil filter, 1 more qt of oil added to bring the oil level close to 7 quarts total and I installed a Perma Cal Calibration test gauge directly to the right front oil gallery that is the same oil galley that feeds the main bearings that is at the right front towards the prop to compare oil pressure to the MicroVision VM-1000 cockpit oil pressure. I test ran the engine and documented the start up with oil at 48f degree cold and warming the oil up to 100F. The Perma Cal test guage read 2 -3 lbs higher than the VM-1000 cockpit gauge throughout the test from idle to 2000RPM at various oil temps, test gauge and panel oil pressure corresponded in equal amounts, slight variation but all good. Being this I eliminated the oil sending unit being a problem or possibly the oil fitting at the crankcase for the sending unit that has the .040" restricted hole from being plugged up. For those that don't know, the .040" oil restrictor is there in case the oil line breaks to slow down the loss of oil. While warming up the engine and oil, I had the same oil pressures within 2-3 lbs variation, so the oil filter was not the problem or the oil sending units. My next step was to remove the oil pressure relief, spring, ball and washers. I inspected the seat that the ball seats against in the crankcase oil galley at the #3 cylinder crankcase location, it looked good but I took the time to apply some dye, lapping compound with an old pressure relief ball and lapped the seat, it had a perfect contact pattern and was seating nicely, no issues there. The pressure relief ball had no nicks or signs of wear, I measured it with a micrometer and it was perfect. I checked the bypass spring with a NEW spring, free length was good and it had the same pressure as a new one, I went ahead and installed the new spring and noted how many shims were behind the spring and put the same ones back in. Did another ground test run, started the engine up and there were NO changes of oil pressure at different oil temps or RPMs. I'm not sure what is happening to cause the sudden loss of around 20-25 lbs oil pressure when its cold or at operating temp throughout idle to cruise RPM 2,450. If I had metal in the oil filter I'd be tearing the engine down but I don't see anything in the filter. My next step is to run the engine, warm the engine oil up, drain and take an oil sample and send in for a report. I suspected my fuel pump diaphragm might be going bad and allowing fuel into the crankcase and deluting the oil, but the vent line from the fuel pump has showed no signs of dripping or leaking, maybe the oil sample will help with this. CHT's have always been in the 300-360f range depending on outside temps. Oil temps have always been normal, no changes in fuel pressure, EGTs all good and peak the same. Timing has always been set at 20 degrees because I'm runging 10:5.1 pistons, bore scope of cylinders show no issues, no detonation issues on piston tops or ring lands. 100LL Avgas all the time, 150F -200F rich of peak in climb, cruise 75-100F rich of peak at 65-70% power. Sometimes lean of peak at low power settings. This engine has always been strong and has never had any issues and it makes a lot power. Its still strong, makes no abnormal noises and runs like nothing is wrong other than the 20-23 lbs of oil pressure that I lost across the board. Possible bearing problem? but no metal in the oil filter, possibly oil pump issues but why such a sudden loss of pressure, possibly a crack in oil gallery which if there was, oil pressure should be good cold but much worse when hot as the aluminum expands and should open up a crack in the oil gallery and making it worse at higher oil temps, but I don't think that is the case, the Woodward prop governor works fine, prop cycles normal, oil galley plug missing?, if one was missing it should have zero oil pressure. I don't see any issues with the Vernatherm as my oil heats up quickly as normal and at cruise my oil temps are normal. I have even used a thermal imaging camera to detect how the fluid/heat is flowing through the oil lines, filter and oil cooler and find no issues. Something that I have not done yet is too shim the oil pressure relief with 5 washer/ shims which should raise the oil pressure 25 lbs across the board from cold oil to hot oil for GROUND RUN TESTING ONLY to see if the oil pump will maintain as a test only. If the added shims don't show any signs of raising the oil pressure, possibly oil pump issues or something else has gone wrong inside the engine that is causing the leak of internal oil pressure. I questioned the piston oiler nozzles but they open at around 40 lbs and should not cause low oil pressure at cruise RPM. It's not a heat related issue of any sorts as I don't have any. I'm at a loss and need some professional advise before I do a teardown at 750SMOH. FYI, I used to be on this VAF forum daily on a regular basis MANY years ago and payed my dues during that time but do to life changing things I have not been on here and after posting this I need to send Doug some $$$$. Any GOOD Technical Advice would help. Thanks, Alan

(reply from Martin Sutter)
Same thing happened to my engine with otherwise healthy parameters. After being unable to find the cause I called Aerosport and talked to one of their engine assembler. He advised me to remove the oil pressure regulator and meticulously clean the steel ball inside and the seat it resides in. When I took it apart I was not hopeful as the ball was only lightly tarnished but nowhere near cruddy. I went ahead anyway and cleaned it to a mirror finish with a soft cloth and some fine polishing compound. Low and behold, problem solved and pressure back to normal.

(from mahlon_r)
I would check the suction screen. probably ok but you should check.
To me it sounds like there is another relief valve operating in the back ground..ie a hole somewhere. A internal missing 1/8 pipe plug would exhibit similar symptoms to what you have seen. If you do get to doing a teardown maybe start with the accessory housing first to check all those rear plugs. Don't think its a bearing with no metal. never saw a crack in a case have so much of an effect on the pressure.
Do you think the prop gov could have an internal leak, that is allowing it to suck up more engine oil pressure than normal but still be able to function OK? Maybe worth trying a different governor? Or getting that one checked?
Any aerobatic equipment installed? if so disconnect and re plumb and see.
Assuming you have a late style pressure relief valve tower and not a short one with a case that doesn't have the centering cage for the ball. But if you have a short tower without the cage in the case it would possibly cause symptoms like you are seeing. easy fix to install a proper tall tower and get that ball centered and functioning properly all the time.
Good Luck,

Five Balls and Clear

Monday I woke to 00000kts and CAVU, and the whole morning's carefully crafted plans immediately went out the window.  I needed go juice so I launched for Bridgeport and its $3.49 gas.  OMG it was smooth.  After the obligatory potty break, and while walking back to the plane, the urge to get a picture of all this blue percolated up.  (My brain talking) "Do you even realize how awesome this is?!?!  It's Monday morning and you're standing on a ramp in bright sunshine with an amazing airplane topped off and ready to go wherever you point it.  Soak this in and make sure you don't forget how lucky you are!!!!  Dumbass."

Above one pano if you have a two monitor setup, and below a regular style pic thrown in for good measure.  I only logged .6, but it reset the mental gyros completely and gave the opportunity to call up approach and get sequenced for the 16L ILS at KAFW on the way back for buttonology stretching.  Crazy crazy smooth.  Even I could pull it off.

Then off to the home office for catch up.  It was worth it.

Superbloom flights ...bruceh RV-9A

My daughter was on Spring break this week and wanted to get out to the desert to see the flowers. Saturday we flew into Agua Caliente (L54) and hit the hot springs for a soak and a bit of hiking to/from the airstrip. After weeks of cold, wet weather, the skies cleared and we actually warmed up a bit this weekend.

Sunday we flew up to visit family in Orange County and on the way up we could see that the hills east of Lake Elsinore were just covered in orange flowers. We detoured on the way back and flew over the hills, which were just amazing.  ...

Electrical Schematic Thoughts ...Paul 5r4

I've received Carl's schematic for dual batteries and he's reinforced to me via emails the importance of being able to get that power to the critical places with no to minimal pilot action. I absolutely agree with the previous post about making your system too complex. That in itself adds a degree of increased risk.

Here's my thinking. I'll have two batteries and one alt. If I have an alt failure, I would be notified of that by the Dynon EMS. If I confirm/agree with the EMS of an alt failure, all I have to do is flip the two switchs to get power from BOTH batteries directly to the avionics and turn off the master switch. Power from the batteries will be direct to the avionics with the only connections being 1. At the battery 2. The relay (power in and power out) 3. The avionics buss connection.

With the Dynon's back up battery and the built in G5 battery along with the two full size batteries up front, I feel this would give me best I can figure an absolute minimum of like 90 minutes to get back to VFR or below the clouds.

Discussion: Carl's stresses the importance of getting the power to the necessary equipment. I agree. That includes battery grounds. Each of my batteries will be grounded side by side to the airframe/engine block.
A thought on the relays that will be the only thing inline between the batt power and avionics buss. The connection for power in and power out of each relay from each battery to the buss. There is of course the wires running into the cockpit for the switch and switch to ground that could fail too.... as well as the switch itself. Here again, There is ANOTHER switch going through the other relay to provide power from the other battery directly to the buss. OK..... What are the odds of first an alt failure followed by a second failure of a relay/switch/wiring connection at the same time and if that WERE to happen, there is the second battery with the exact same setup to get power from that OTHER battery to the buss? Admittedly I'm just learning all this stuff and am speaking from probably the most inexperienced point of view on VAF.

Reviewing my own schematic, I see there's a single point of failure at the 25 amp pull breaker. If that did happened it would only make sense to turn off both "direct to" relay switches again and go back to the battery only side of master to get power to the avionics buss. I wonder if it would make sense to leave the batt side of master on from the beginning of the alt failure and turn on the two "direct" source switches. Of course this last would add the importance of sheding all unnecessary loads from the main. The advantage is now there are THREE ways power is getting from the batteries to the avionics buss.

Any thoughts are appreciated.

What keeps you from flying aerobatics? Really? ...poll

Sometimes I feel like I am beating my head against a brick wall. I have enjoyed flying competitive aerobatics in my RV since 2006 and have done my utmost to encourage others to do the same. Last weekend an aerobatic training session was held at Siler City Airport (KSCR) and numerous RV pilots contacted me, anxious to come out and participate or watch. We welcomed sunny skies and moderate temperatures on Saturday morning and I was the only RV pilot that showed! Where are you guys? In an effort to answer that question I have posted the accompanying poll. Those of you who are flying aerobatically capable RVs (RV-3,4,6,7,8,14) please give me honest answers to the poll and I will try to address your questions and concerns in this thread. Thank you for participating.


Refurbished RV-4 ...Chris Copeland

Purchased a flying aircraft built in 2000. Low time, High quality build and well equipped with tall gear, O360, CS prop, etc. Exterior was John Deere green and interior was cheddar yellow. I spent the first 6 months of ownership doing a complete strip and repaint taking care of any needed maintenance along the way as aircraft was disassembled. Flying the aircraft now and having a blast with it! Previously owned a C-140 and a Citabria 7eca. Both great aircraft, but the RV is definitely another level of fun!


Aborted RV-8A Wing Install

Sorry if this has already been covered extensively on the site. Please point me to old posts if it has.

I attempted to install wings today and ran into a snag when the landing gear weldments kept bolts from penetrating spar. Aircraft is on gear with engine installed. My team, which includes multiple RV builders (all taildraggers), concluded that the weldment shifted due to the extra load. My plan is to lift the fuselage off the mains and loosen the inboard weldment bolts to get the wing bolts better aligned.

Appreciate any comments confirming that approach or something more ingenious.

  Good morning!  Fast weekend.  Spent Saturday working a side job to help supplement the scratching out a living thing, but managed to get a short .2hr RV hop Sunday after Mass.  A lot of locals did the same Sunday, as there was a big high pressure capital 'H' over Texas and Oklahoma all weekend.  Some basketball on TV and lots of VAF work and the weekend was outta here.
  So there I am Saturday KRVS in Tulsa, OK at the aforementioned scratching, and what do I see taxi by?  RV of course.  At KRVS (pic).  Kinda fitting. ;^)  Crazy busy there Saturday morning.   I think every plane in the area was flying.
  Hope you had a good weekend.

Carbon Fiber Rudder ...ATangle

I've been working on making a carbon fiber rudder (RV-8 drop-in replacement) for a little while now and finally have a little bit of progress to share. I just fabricated the skins this past week while I was home from school for spring break. This project is primarily for my own education with designing/fabricating composite parts, and I'm quite happy with how the skins came out. The look is a bit different than the stock RV-8 rudder, with some influences from the GB1 Gamebird.

A.O.G. Update ...Guy Prevost RV-10

Steve McLeod, a local A&P showed up with tools today. He was knowledgeable and willing to work with me, not just grumble about experimentals. I mostly needed access to tools, but he was far more useful than that and a good value too. I guess he maintains a few RVs around these parts.

We test ran with normal ignition checks etc. No issues. When I removed the upper cowling this time, I noticed the (relatively new and not well set) aft baffle seal was turned backwards. One of the things I had really noticed when the problem appeared yesterday was significant cowling vibration and extra pillowing between camlocks. The Mrs and I looked hard for a cowl problem because that’s what it felt like.

Intake gaskets were all good, but the intake tube from the sump on #3 was loose. They were all just re-swaged at engine rebuild 120 hours ago. Ugh. It wasn’t loose enough to go anywhere; we repositioned so that its sitting well, cleaned and applied RTV. A temporary fix for sure.

I just finished flying .75. No roughness and all CHTs and EGTs normal. #3 CHT did not run up high like it had the last couple of takeoffs. Completely nominal. Climb to 6500 was normal. Flew high and low MP at different RPMs. No issues. Leaned to a about 35degrees LOP and did an ignition check. A slight change in tone and then smooth. All 6 EGTs slowly increased, but no roughness.

In my RV8 I found several issues the first few times operating out of lowland airports. I live at 6k’ and mostly fly places that are as high or higher. My canopy skirt would buzz against the fuse at high IAS, something nerver achieved at home. On another trip, a wing root fairing let go. All of these items were associated with descents into near sea level airports. I think that the rear baffle seal either got flipped at cowling installation or that the increased pressure from high IAS (and pressure) descents into these high lowland airports flipped it.

Since I found solutions to both anomalies I was experiencing and can’t reproduce them after those repairs, I’m headed 30 minutes South. There are lots of friendlys at GTU, but the best runway for today’s conditions is closed. EDC has a car waiting for me, and is closer to family so that’s the plan for now. I’ll report in later today.

I haven't posted here in quite a while. I'm finally at the airport working on final assembly. If you look closely, you may notice I started this thread (2010). Yeah, it has been a slow build.


Suggestions to finish this off?

RV-8, Right Elevator.  I am fitting everything prior to final assembly of the component.  I still need a little more sanding on the E-612 fiberglass tip as it sits proud of the weight.  Just wondering what others have done in this area to finish off the forward edge?  Maybe a flox mixture to smooth over the lead counter weight?


Rolling Tool Box Project ...RV7ForMe

Hello.... quick update. Nothing really moved forward on my own airplane. In fact it actually went backwards as i gave some build parts to my buddy for his rebuild to save some time to get his RV back in the air. I got new parts for it and the promise I will finally get some right seat time in an actual RV7! Never flown one

In the meantime. I saved up a bit of money and wrote Vans a check for the Fuselage kit! Big decision time here. It will be an RV7-A I went back and forth a lot on this decision and reviewed my mission and while I think the tail dragon is waaay sexyer the nose dragger is just a bit more practical. YMMV of course, but the decision is done.

Also, to give credit where credit is due. Somebody on this forum posted a very nice rolling tool box that insprired me to get one myself. Until now my own project never requried it but since my tools have been at the rebuild project it is actually really convenient to have a tool box that rolls around the airplane once parts get big. Also I just think it is very cool......

Damn Storms

You know you got a lot of rain quick when you find a crawdad trying to cross the runway during a FOD check.  Relocated to the creek...

We had a squall line and some TSRA come through the area around 0500 local Wednesday.  After the line passed, the air was still and clear.  I drove out to get on the treadmill for an hour and lift weights, but the sky was so blue I opted for Plan B - a short flight.  I'll exercise after dinner...

The Luscomb upside down is over at a friend's private strip east of Propwash (I texted him after I landed in case he didn't know about the damage to the north end of his property).  Found out later there were several planes moved around at both Denton and Grand Prairie.  Lots of bent metal around, but I haven't heard of any fatalities thank goodness.

RV-10 Build Status Report ...LCampbell

On to some bigger pieces now, as work is well underway with the horizontal stab. I’m getting most of the tail feathers up to the point of closing them up and pausing, prior to a visit from my tech counselor to double check that I’m doing things in a manner that won’t put life or limb at risk.

One thing I started to notice was that the dust from deburring with the 6 inch grinder and scotch-brite wheels, wasn’t staying in the immediate vicinity of the grinder like I thought it was, I was finding it 10-15 feet away and it was starting to get on everything. So, a trip to Home Depot, and for less than $40, I’ve got a great solution of a fan, filter, and bit of tape, to help keep the dust in check, and it seems to be doing a great job.

One other tweak, on the HS cradles, I didn’t like how they wanted to crease the metal (they didn’t, but looked like they wanted to), so I grabbed some 1/32 in plywood from the hobby pile, and made some quick 2 inch wide ‘feet’, and simply attached them with some tape, to widen the pressure/contact area, and liked the result.

Panel Upgrade: Old vs New ...flyr747


Snorkel Status ...scottmillhouse

After all the tales of whoa, surprisingly mine fit with lots of trials and small cuts at baffle side. No butchering and glass work. Appears it is designed to fit a real Lycoming and not a clone. Getting the filter in was challenging due to tight space. I had to take a lot off of the cowl and made a filter cover cap that tied in the snorkel side, side baffle and cover.

Phase 1 Complete: Panel Upgrade ...BVD

I've pretty much completed phase 1 of my panel upgrade. I wanted to upgrade the panel with modern tech, a better autopilot, and reduce some of the weight and complexity without cutting a new panel.

I've already started thinking about phase 2 which will include a new panel I'll build on the bench. However, I'm gone 8 months of the year for work, so it'll probably be a while before it's completed and installed.

2019 Ice Cream Social Writeup ...AX-O

We had a great turn out despite the WX being somewhat bad North and South of us. We really lucked out. For 2 weeks ahead of the Social, the WX has been weird. Wet particles falling from the sky, winds on Fri got up to 50ish kts. Made arrival for my buds somewhat difficult. We got rid off a ridiculous amount of sugar. 8 gallons of ice cream and supporting toppings were gone. If you have pictures of your trip or the social, please post them as my wife and I don't have much time to take picture.

Yeap, we stuffed 9 additional RVs (well one rocket too) in this small space over night. No need to tie down outside in those winds.  ...


Active Duty Air Force RV Builder Needs a Solid ...Raven31

Hey guys, I’m active duty Air Force and started building an -8 back in October. The tail is done via builder assist and I was planning on continuing to build with synergy but the work schedule has changed and I won’t be able to take leave as frequently as I thought. Also, I’ll be moving summer of 2020 and don’t know where yet.

My QB kits just arrived in the US and I don’t really want to move the project multiple times and I was curious if there is anyone in the SC area that would have any interest in being a mentor/builder assist? The thing I liked best about builder assist was the guidance and “do this next” so I wasn’t staring at the plans trying to figure what to do next.

I don’t know how much I could get done over the next year working a few hours at night and however long I could on most weekends


Milestone: First Power Up ...Driving '67 RV-14A

First up, A special thanks to my friend/mentor Art for his help, guidance and encouragement for this challenging part of the build.

We finished up the wiring of the Avionics harness and electrical system in the past week. Yesterday powered up the panel for the first time. Everything came on line, talked to each other and NO smoke ..... Woohoo!!

Time to call Steinair to finalize the panel details and get it cut and painted.

Now back to the Salt mines to pay for this affliction!

Electrical Gremlins ...dbegeman

I have an issue that has been bugging me since I bought my airplane a year ago. Unfortunately I didn't realize it was an issue until after the pre-purchase inspection was done and the paperwork signed.

What happens is, when ever I push the PTT button (on either stick) my manifold pressure gauge starts decreasing and the ammeter deflects 180 degrees from zero amps. It does it on either radio (ICOM 200 and a Bendix/king nav/comm) and with the engine running or just on battery power. The ICOM makes the ammeter deflect one way and the Bendix/King the other way but both deflect 180 degrees from zero amps. In addition I have a switch labeled AMP that on the right selection says ALT and the left selection is unlabeled and I have no idea what function it serves. I included pics (and hopefully I can lable them). Any help would be appreciated!!





Q: Electrical Schematic Capture Software.  Getting to the point in the build where I need to get my electrical schematics into shape (from the back of the envelope scribblings) and looking at something better than Visio 2003. I ran across KICAD - it is a open source schematic capture and PCB design tool and while it has some interesting features is pretty straightforward to use and has a comprehensive library of components suplimented with the Digikey library of parts. It runs on Mac,Windows PC and Linux, and the price is right. Worth taking a look if you dont have a current copy of Autocad or the Solidworks schematic capture tools.

A: For a long time, I had access to an industrial-grade schematic capture package (Altium), but not when I started my RV7 electrical system. I decided to go with Visio since I didn't want to go through the tedious task of making all the symbols for all the component (connectors, pin numbers, etc) or did I want to spend any $$$.

However, now that I'm at the other end of the job, I would do it over with a basic schematic capture package. Though the schematics aren't as "pretty", one of the most useful things you can get from the capture package is a netlist of connections. This is super useful when you're running wires through the ship and routing them to the correct boxes. I had to basically do a manual version of this to make the install efficient. The schematic capture packages do it for free, and maintain it for free.

Find your favorite free version (kicad is good) and spend the time up front; it will pay off in the long run

Shimmy ripped off nose gear fairing

...Michael Wellenzohn RV-10

Hi all,

I wanted to share a surprising shimmy experience and would like to know if anyone had ever had a similar experience with the —10.

I was landing with probably 10—15kt crosswind from the left and experienced, after the nosewheel came down, a short shimmy (hard surface RWY). I taxied back to parking where I was surprised to see that about half of the rear nosewheel fairing was ripped off.   I am flying my -10 since 2013 and nothing like this ever has happened. On my last annual I checked and varifyed the breakout force, and I’ll check again next time I’m in the hangar.  My hypotheses is that the crosswind might have forced the nosewheel out of center and started the shimmy after touchdown.


The first ice cream social pic...

...from this past weekend.  More to come.  AX-O said he would get me some pics down the road when workload allowed.  He did send me one from the start of the day, and it was so good I thought I'd share it now.

How JohnInReno Did It ...clamping vent for RTV set-up

Some of the common "Quick Clamps" are reversible so they push apart. I used a 2x2 and clamp to hold both sides against the fuselage.


Status Report ...jcarne 7A

Well the weather has finally turned into a Wyoming springtime (30s) which means it's time to go full steam again in the garage! I'm looking forward to a productive work year, perhaps so good that I'll be flying at the end of it!

The firewall insulation has been on my mind lately so I decided to just tackle it and get it done. First I went through and drilled a hole mess of holes in the firewall for various things. I ordered in a piece 0.020" titanium from TMS Titanium, this was quite honestly cheaper than the titanium foil some people use and I simply don't like the look of the wrinkly stainless. I'm not done yet but I am glad I went this route, it seems very sturdy and when it gets riveted/bolted down I don't think there is going to be very much wrinkling.

First I cut the sheet on a foot shear. Cutting the sheet is for letting the fibrax below a path for off gassing in the event of an engine fire. Next simply trim them to fit on the firewall. against the fuselage.

Tate:  Getting it done back in the day.

Today I have some wonderful family news.  At 7pm Friday night, as instructed, we logged on with our special ID number and got the word our son Tate was accepted into SMU (see the letter).  He was, as you might suspect, at his after-school job cooking burgers.  Of course we texted him (and his sister, and his aunt, and his...).  He has an intern gig already lined up we think for the summer in the same lab his sis spent a few years in.  He's looking at Chemistry.  I see a trend...

This kid absolutely crushed it the past couple of years - all A's.  And I know he worked hard at it. 

I was cleaning the carpet Saturday, and while waiting for the foam to dry so I could vacuum he explained to me, Hello chemistry!, how the electrical properties of the soap molecules help bind them to the oil and dirt.  I acted like I understood.  I think he'll be fine...

And he can weld.  And land a Cub.

Tate, your Mom and I (and the rest of our family and friends) are so very proud of what you've done with your life so far, and how you carry yourself.  Character counts, and you've got it in abundance.

VAF friends, thank you for indulging a proud Dad while he brags on his kid for a bit.  Many of you have known him as long as I have, and are punching a fist in the air just like me.

Look out world!

Landing light install....frustrated ...Reflex

After surfing through various web sites, searching the Van's store, and running a few searches on VAF, I decided I need to get a bit of advice. I'm having trouble figuring out how to install the landing lights on my -14.

Based on my searches and common sense, it would appear that the landing lights would need to be installed to W-00017 before riveting it in place. Unfortunately, I didn't figure that out until I had the left bracket installed.

At issue: How does the landing light install/connect to W-00017?

Since wing wiring is going to take place very soon, it would make sense to do the installation of the light (or at least the prep) now. The plans in section 17 do not address this. It would seem to me that Van's would have given at least some indication of what is needed at this time.

Questions:•Is this indeed the right time to install the landing light(s)?
•What size light will/should or is best to fit in the wing?
•What is needed to connect this light to the air frame?
•Is there any way to do this AFTER W-00017 is installed?

I'm a bit frustrated by having to take valuable build time on a Saturday morning to post on something as simple as section 17. (By the way, gotta love the verbiage on 17-09; step 1 last sentence.)

Sorry for the rant. The kit and plans have been excellent to this point and the fit and finish are beyond excellent. The verbiage in the written instructions just leaves a bit to be desired in a number of places.

Many thanks to any of you who could take a look at the questions above and give me your thoughts.

Pinholes while painting the interior my RV

I'm sorry if I don't know the terms in painting, but according to my research what's happening to me is called pinholes. I have these little dots of contamination, like those little balls of lint that you get in your clothes.

I've cleaned the fuselage thoroughly, vacuumed it, compressed air, then water and alcohol until it was spot on clean.

I built a homemade paint booth with an inlet and an outlet all amounting to positive pressure to avoid drawing dust into it, I wet the floor to avoid dust or fallen paint from rising back up into the cabin but no luck.

RV painters, How have you approached this? Any advice?


Night flying in experimentals

Q: How do people go about getting permission to fly at night? I have the required lights installed, but the FAA inspector that inspected my plane pointed out that FAR 91.319 states:

"(d) Each person operating an aircraft that has an experimental certificate shall -

(1) Advise each person carried of the experimental nature of the aircraft;

(2) Operate under VFR, day only, unless otherwise specifically authorized by the Administrator..."

There is nothing in my operating limitations that specifically prohibits night flying, but it does state I have to comply with FAR 91.319.

I guess I have the same question about flying experimental airplanes IFR, however I don't intend to do that. The inspector, while helpful, was very obviously not willing to negotiate limitations in the regs so I didn't press him about it.

A: (Vic) You didn't mention when you received your operating limitations. The last few Orders allow night and IFR if properly equipped after completion of Phase I.

Here is the exact wording form Order 8130.2J. BTW, you can always ask for new Operating Limitations from the FSDO. But, also bear in mind that the DAR and/or FSDO inspector does have the authority to tighten the limitations, but never relax them.

22. Night flight operations are authorized if the instruments specified in § 91.205(c) are installed, operational, and maintained per the applicable requirements of part 91. (48)

23. Instrument flight operations are authorized if the instruments specified in § 91.205(d) are installed, operational, compliant with the performance requirements of, and maintained per the applicable regulations. All maintenance or inspection of this equipment must be recorded in the aircraft maintenance records and include the following items: Date, work performed, and name and certificate number of the person returning the aircraft to service.

Wing Tip Spliting

Having a heavy wing issue. I corrected some of it by rerigging the right aileron which was off by a good 1/8-1/2 inch. I flew today and while it's much improved it's still heavy on the left side.

Looking at my wing tips, they're not aligned with the ailerons, which are aligned with the flaps, which are aligned with the bottom of the fuselage. There's no control surface twists either, all the rivets line up. Here are a few pictures.

To me it makes sense to correct the right one first. Go fly and if I then have a heavy right wing then correct the left one.

I'm not 100% sure on the technique used to do all this. I'm guessing you just dremel across and 'split' the trailing edge. Then pull it up where it's level with the aileron. Then drill some reference holes to cleco later. Sand the inside flox back together and cleco to dry.

Does that sound about right? If I cut too much off when splitting can I fill with milled fiberglass vs flox or maybe use some fabric?

RV-8 and the Hoquiam Bird Walk ...Steve Rush

Saturday 3/2/19 was a rare clear day here the PNW. The snow and ice was on the run and we could finally see the ground again.  Hoquiam is a nice little spot way out on the coast. It used to be a more common destination when the restaurant was open, but it closed several years ago. It is still a nice place to go for a walk.


Nose Wheel Breakout Force

Q: Have any of you had to re-adjust the nose wheel breakout force after flying for a while?

A: Yes, mine went loosened up to 16lbs before I was finished with phase 1. Tightened back up to spec and I'll check it again before leaving for SNF.

A: Some loosening after gaining time in use is totally normal.  I usually recommend that people check it (regardless of RV model) after 30-40 hrs and then again at 100.  After 100 it usually doesn't change much.

Old Thread, New Shimmy ...Joe Wilber

Resurrecting an old thread here.

I've been flying for about 1.5 years and have *never had a nose wheel shimmy problem. This morning I landed in some moderate cross-wind conditions and the landing was a little sloppy, coming down onto the nose-wheel quickly after the main gear. And there was a shimmy during roll out. The shimmy remained until I turned off the runway.

Several months ago I noticed the same thing. As I recall, that time was something like 10 gusting to 20 all crosswind and I had the same issue. I quickly put the nose wheel down after landing an the nose shimmied during roll out until turn off.

I fly about once a week and apart from these two incidents my nose wheel does not shimmy.

Anyone have any idea what might be going on here?

Shawn's RV-7 (Desert Garage Works) ...Gilbert, AZ

I finally got started on actual plane construction (barely) and thought it is a good time to start a progress thread.

Working now to sand down those nasty file marks left from "breaking" the edges.

The LONG version, from the start . . .

I got first taste of an RV about 2 years ago when my cousin took me for a brief ride in his RV-7. From then on I was hooked and knew I need to get one "some day." I read about the kits on the mother-ship website and knew that building one was an experience I wanted.

This past June (2018) I sold my house and moved into one with an awesome garage setup. It has a two car garage and a separate one car garage. At that point I had planned on making the small one-car garage a "shop" for working on r/c planes and other small projects.

Soon after we moved in, my wife decided she much preferred to pull her car straight into the small garage, as opposed to having to make a hard left in the driveway to get into the bigger garage. It was then that the larger two-car garage became mine. ...


Build Status Report ...goatflieg

I've posted a new Blogspot entry. It's another long one chock full of lots of little firewall-forwardy details. Yum Yum. Click on the Blogspot link in my signature below. Here's the teaser photo:


SUN 'n FUN Homebuilt Parking Change! & NOTAM

I am involved in planning for this year's SUN 'n FUN event, and wanted to relay important changes to the parking plan, changes that will allow us to linger, inspect and otherwise enjoy other folks craftsmanship.

Our former Homebuilt parking area was just north of the central (core) area of SnF, and this parking sat right under the lateral path of our showcase flybys--which are flown at 500'. Because of FAA regulations concerning flight over populated areas, the FSDO allowed us to park aircraft there but the occupants were not allowed to linger in that area after parking.

Naturally, we want to see each other's aircraft--comparing innovations and enjoying other people's build quality are some of the joys of what we do. We received a lot of well-deserved complaints in the past three years over the requirement to vacate that parking area during the flyby period, which normally takes place between 10 am and the beginning of the airshow, normally 1 or 1:30 pm. That's a lot of time required to be outside the area you wanted to be in. You made valid points, and we listened.

Our new Homebuilt parking area is evolving--and this year's efforts are part of a multi-year push to expand and enhance your SnF experience. This year's primary Homebuilt parking will be located on the south side of taxiway E, just to the east of Vintage. Overflow Homebuilt aircraft will be taken to the north side of E, just across from the main parking area.

The good news? This area is NOT inside the overflight clear zone, and you WILL be able to remain, linger, drool, covet, envy, inspect, polish, buy, photograph, and otherwise enjoy all of the other Homebuilts in the area full time, regardless of flybys or even the air show. This area is just for parking (no camping), and your windshield sign should read HB to get there.

If you wish to camp beside your aircraft, the normal Homebuilt Camping area has not changed locations. Use the HBC sign to be directed to that point.

We are rolling the area prior to the show to ensure smoothness. We will also compress parking spot distances to ensure we get as many aircraft into that area, but of course we will do so with the safety and security of your aircraft in mind. We don't move aircraft after they have been parked and positioned with the owner present.

Feel free to contact me if you have questions or concerns. Our job is to provide you a great experience at SUN 'n FUN, and I promise we will do our best.

Oh--and here's the NOTAM. There will be minor revisions, so be sure to look for those before you take off.

Fly safely-
Sam Huffstetler, aka "Flipper"
Chairman, Air Ops

Fantastic News!!! ...RV8Squaz

I am happy to announce with great pride and joy, that our very own Ron Schreck has been selected to be the Contest Director (CD) for the 2019 US National Aerobatic Championships!! This is a huge deal. It is a tremendous honor and responsibility. Ron will be responsible for organizing and safely and efficiently running the week long event which will involve the coordination of about a hundred competitors, dozens of volunteers, and all of the similar logistics you would find at a small air show to include food, hangars, vehicles, etc. Adding to the complexity of the event is that we will be operating out of a new venue, Salina, KS. And I know my buddy is up to the task (although he feels a little overwhelmed at the moment ) Here is the official announcement from the IAC:

Submitted by Executive Director on Fri, 2019-03-01 21:56

At a Special Teleconference Meeting of the IAC Board of directors held today, Ron Schreck IAC #433751 was chosen, by unanimous affirmation by the Board of Directors, as the Contest Director for the 2019 U.S. Nationals to be held in Salina, Kansas, 21-27 September 2019.

Ron is a member of the IAC Board of Directors and serves as the South Central Regional Director, a position he has held since he was elected in 2016. Ron lives in Gold Hill Airpark, North Carolina. He is an Intermediate competitor in his RV-8 Miss Izzy and a National Judge. Ron was also a member of the aerobatic formation team of AeroDynamix where he was the flight lead. A graduate of the U.S. Air Force Academy, service in the United States Air Force as a fighter pilot for over 20 years, and a career as a USAir Captain, Ron has an excellent background as an organizer.

Ron reported today that he already has begun work on the foundation of the Nationals by arranging to meet with airport officials and the Visit Salina!, the Salina Area Chamber of Commerce, in Salina on March, 25, 2019. He will be joined by IAC Chapter 119 founding member A.J. Hefel of Wichita, Kansas, who will be his on-site liaison in the coming months.

Ron has the full support and encouragement of the IAC Board of Directors and we are looking forward to a successful in event in September."

So there you go, an RV guy as the CD of the US Nationals Aerobatic Championship! RVs are respected and welcomed at IAC events all over the country. RV participation is desired at all levels in the IAC. If there was ever a time to join the IAC and participate in the many fun events, the time is now! Why don't you join in on the fun?! I hope to see you at a future contest or chapter practice day sometime!


N803DR Performance Numbers ...j-red

Just another data point for comparison with other 8 owners and builders.

After a few hours learning how to fly (and particularly how to LAND!) this thing, I've got the confidence needed to install the wheel pants and gear leg fairings without subjecting them to assured destruction!

Lots of work has gone into these, and they're still not perfect, but I think they turned out pretty good. 


Hit a milestone on Sunday ...Bill R.

My 10 year-old asked to go flying on Sunday. Now that he can see over the panel (with the help of a stack of cushions), he is more and more asking to go.

He did his usual great job of flying us over his school, over a new highway extension, looking at the Bradford Pears that are in bloom, etc. All while doing a great job of holding altitude.

When I filled out my logbook after the flight, I realized I now have 1001.2 hours of tailwheel time. I feel like counting tailwheel time in an RV is cheating since they are so easy to fly!

That's OK because someday, someone with a P-40 might need someone with a thousand hours of tailwheel time to fly it for them.


Build or Buy ...Danny King PIREP

It's a very personal decision. I started the Doll September 1997. The quick build option was months away, so the only option available to me was a slow build. Buying? Not a chance. As best as I could calculate, the Doll was the 20th RV-8 to fly. No one was selling RV-8's in September 1997! Why not an RV-4? I love the 4, but she is a little too small for me. My 5' 8" wife was cramped in the back seat, and cargo space was too sparse for the two of us. So....I ordered the RV-8 tail and wing kit. Two years and seven month later the Doll was fully painted and ready for her first flight. I did not consider the building experience work. It was pure joy! So why does it take builders ten years to assemble a quick build? I really don't know! I was flying a Boeing 727 fifteen out of thirty days every month during the 2 year 7 month build. I was in hotels away from my shop two or three nights on each of those trips. When I was home I put in the hours, but it really wasn't work. It was fun and joy and pride of workmanship. It was a tremendous feeling of accomplishment.

Watching the admiring crowds around the Doll at Oshkosh 2000 was incredible. Van himself left his tent and inspected Beautiful Doll parked out in the west field now known as EAB camping. What a Rush!

I never added up all the receipts but I figure I first flew the Doll for around $55K with steam gauges and a rebuilt used engine. Since then, engine and avionics updates have put the investment around $85-$90K. She's not for sale, but if she were, you could not get her from me for anywhere near that number!

Someone posted.... you have to include the "cost" of the work in the amount invested. Someone else said to substitute the word "Joy" for "cost". I can tell you it was all Joy! It's been over 21 years since I drilled that first hole, and the joy continues along with a big RV grin every time I fly her!

Note: Having flown three different RV-4's and 26 different RV-8's I think the 4 edges out the 8 in pure flying characteristics. So Smokey Ray.... you're right on there! The RV-4 is a wonderful flying machine, and the easiest taildragger I've every landed.


You Never Know ...Iron

...where you’ll find EAB (or RV) guys....years ago, I was showing the Snowbirds around the old Mission Control Center, and when I was explaining flight director call signs, and that mine was “Iron”, one of them pointed at me and says “Hey, you’re Iron Flight! We know you - I’ve got an RV, he’s building one, and he’s got one (pointing at other Snowbirds)”

Turns out they were a bunch of good old bush and RV pilots at heart....

Fast and Slow ...Carlos151 RV-8

As most of you know, joining the 200kt club in our machines is a regular occurrence. I was just out playing last week and with these crazy winds we've been having in the TN valley, I recorded my fastest and slowest ground speeds in level flight yet, with not a whole lot of effort.

Heavy Iron - RV brotherhood day

Since there was an RV-Lancair brotherhood thread, I didn't think this would be out of place.

Just got finished with my every 9 month dial-a-disaster experience in the B737 simulator. I've been on this plane so long I usually know the other pilot and the instructor.

However, today both the copilot and the instructor were new acquaintances and for the first time ever for me - we all had RV's. So the requisite emergency procedures and limitations oral was interspersed with discussions of cool places to fly your RV. Johnson Creek, ID is now on my planned trip list.

Former military pilots used to make up a majority of hires at my airline - and they frequently avoid (or have never done) GA flying. We have a lot more civilian only pilots now, so my experience today may become more common.

Mag Failure - Check Slick SB 1-15A ...TimO

I figured this is a good one to post here, because many of us ordered engines and built RV14's with engine from the same era.

I had a complete mag failure on my one and only mag in the RV-14. It was first caught on the ground, during run-up, and it wasn't vague at all as to there being a problem. Once I tore into it, what I found was pretty unexpected, yet based on the parts Slick was using at the time, I believe many of you will fun into the issue if you have affected mags, and it is absolutely a good one to take care of. I hadn't caught this Service Bulletin until now, so now that I'm aware I want to make sure you know about it too.  ...




Aircraft On Ground (AOG Stuck).  Now Fixed ...MConner

On landing the pitch trim would only run nose down from either stick, not up at all. After landing and fiddling with it I see that the tab on the copilots side is full up and the pilot side is just a little nose up above neutral. 

Ok I appreciate all the support. I can hear the relay clicking in both directions. I did run the trim full forward without meaning to a little at the time while troubleshooting it.

Thank you for being part of this forum and helping me understand how the system worked.


Help: Cracks in Landing Gear Mounts ...mbauer

That time of year: improving cabin heat ...Dugaru

I've had some modest success improving the cabin warmth of my RV-9A, and I owe it all to the various posts here. So I thought I would list what I've done, in the hope that some other freezing RVer might find this info useful in the future.


RE: RV-12 'Rudder Slip'

(Scott M. reply)
The RV-12 uses plastic bushings as guides for the rudder cables (all of the RV models do actually but because the skins are predominantly thinner on the RV-12 it can resonate the noise they sometimes make, to a higher degree).

It is fairly common to hear a rubbing / screeching sound on the ground when moving the rudder pedals. You may have just noticed a change in yours because of different temperature, slight wear in the bushings (this is normal... they typically last for thousands of hours), etc.

It should still be investigated to confirm the source since we can not hear what you are hearing, so there could still be something else causing it. What for sure is not the cause, is loose (they are loose by design until you put your feet on the pedals)or stretched cables.

Superior Buyback




The company is contacting each XP-382 and XP-400 series experimental engine owner to arrange to immediately buy-back their engine.

Coppell, TX (March 01, 2019) — Scott Hayes, VP, Sales and Marketing for Superior Air Parts, Inc., announced today that the company is implementing an immediate and mandatory buy-back of all the Superior Air Parts XP-382 and XP-400 series experimental aircraft engines in the field.

“This is not something we want to do, but the safety of our customers is our utmost priority. Because of that we are contacting every Superior XP-382 and XP-400 engine owner to arrange to buy-back their engine,” Hayes stated. “We know it is a considerable inconvenience but again, safety of flight is paramount in everything we do.”

“We have already contacted a number of our owners and while it’s no surprise that they are not happy with the situation, they understand that we are doing this because it is the right thing to do,” he said. “In fact, the typical response has been them thanking us for keeping their safety as our top priority."

Bill Ross, A&P I/A and Superior Air Parts’ VP Product Support explained that the company’s decision to take all of the XP-382 and XP-400 engines out of the market comes after a lengthy evaluation and testing process.

“When we first learned of the breadth of the detonation problem, we contacted XP-400 engine owners and paid to have them ship their engines to our facility for evaluation,” Ross said. “We disassembled, inspected and tested the key components in each engine.”

“The good news was the majority of the engines were absolutely clean, with no signs of stress wear or damage,” he said. “The bad news is of the few we found with issues, neither our engineering team or our metallurgy specialists were able to define a consistent root cause of the issues.”

Ross added that even after the company took all the available steps to adjust the engine’s ignition timing to reduce internal stress, the results were still unsatisfactory. So to eliminate the possibility of any future occurrences, the company is grounding all XP-382 and XP-400 engines immediately.

While the detonation problems are currently confined to the XP-400 engines, Hayes said that because the XP-382 shares so many of the same internal components, that the decision was made to include that model in the program as well.

“I want to be 100-percent clear that the grounding and buy-back mandate does not include any XP-320 or XP-360 engines,” he said.

“Throughout Superior Air Parts’ 50-plus year history, we have stood behind the quality and safety of our products,” Hayes said. “While the financial burden of this buy-back is significant, it is not as stressful as thinking that we have failed, in any way, to do what we could to protect the safety of our customers and their passengers.”

Auto Paint ...Rob Traynham RV-7

I recently took a day to clean and wax our RV-7 (originally built by Brian Carroll) which was painted with automotive paint. I remembered reading threads about the advantages and disadvantages of this type of paint system. A recurring question was, “ Yeah, but how well is it going to hold up?” So, to answer that question, I thought I’d offer the following photographs, one made almost nine years ago just after painting and then, another set made yesterday. Brian and his friend Corky Robert’s did this in Corky’s paint shop. I have experienced and operated aircraft ranging from a two-time Oshkosh winning Champ to a brand new Gulfstream 550 and this is, by far, the best paint, both in gloss retention and durability, that I’ve ever seen.
