Default Instruments

Hi Jose, for instrumentation requirements in Australia, we're still required to have a direct reading compass in addition to the EFIS magnetometer. I haven't planned on installing a transponder initially because I live and fly in a rural area where there is no radar coverage. But if required I could add either a remote transponder with the Dynon, or a round head unit e.g. Trig with the round gauge panel. Same goes for ADS-B.

Per Australian regulations for private flying (flight and nav instruments):

Day VFR equipment CAR 174A, CAO 20.18 Appendix 1
The flight and navigational instruments required for flights under visual flight rules are:

an airspeed indicating system, and
an altimeter, with a readily adjustable pressure datum setting scale graduated in millibars, and
one of the following
a direct reading magnetic compass, or
a remote indicating compass and a standby direct reading magnetic compass, and
an accurate timepiece (clock or watch) indicating the time in hours, minutes and seconds (may be carried by pilot or crew).


The panel design will probably evolve a bit more while building the rest of the plane but I want to try and keep it simple! Thanks, Paul.

Default Direct reading Compass

Hi Paul,
My RV7 has a Dynon system and no direct reading compass.
Based on the below.

CAO 28.18 also says..
Other aircraft in private, aerial work or charter operations

3.4 Subject to paragraph 3A.3, an aircraft:

(a) engaged in a private, aerial work or charter operation; and

(b) not mentioned in paragraphs 3.1 to 3.3;

may only be operated under the V.F.R. if it is equipped with the following:

(c) the instruments specified in Appendix I;

(d) any other instruments and indicators specified in the aircraft's flight manual.

3A.3 Paragraph 3.4 does not apply to any other aircraft that operates under the V.F.R.:

(a) being an aircraft for which a current certificate of airworthiness as an LSA has been issued; or

(b) being an aircraft for which an experimental certificate has been issued under paragraph 21.191 (g), (h) or (j) or an LSA for which an experimental certificate has been issued under paragraph 21.191 (k), of CASR 1998;

if equipment is carried that provides a pilot with the same information that would be obtained by compliance with the requirements of Appendix I for operations by day, or Appendix IV if approved for operations by night.

So legally have the “same information” as the list all in the Dynon setup.

Now is it sensible to not have a direct reading compass?
I fly VFR day only ……with the following
Dynon
My ipad OzRunways and google maps etc
backup ipad
Iphone
Often also my wifes Iphone.
I am comfortable without a direct reading wobbly compass.

Default Wings fitted (temporarily)

(thanks Rob for the clarication on carrying a compass)

Younger Me completed the RV wings in 1997 and since then I have been storing and carting them around each time we moved house (3 times). Yesterday we attached them to the fuselage for the first time ever! and fortunately everything fit. The rear spar attachment forks aligned without any interference and I admit I was a bit concerned about this being a potential problem.

I've pinned the spars in position with 3/16" garden stakes that made fitting quite easy.

There are some discrepancies on the plans for rivets and bolt holes around the gear socket area so I need to think over and work out what to do there. I also want to set up some sort of jig to drill the holes for the 5/16 bolts that hold the gear legs in the sockets. They legs are hardened spring steel and are not pre-drilled like the newer kits.

It was great being able to just pull the wings out of storage and fit them, like a quick build kit, it makes the project suddenly look like a plane that may fly someday!

Default Main gear alignment and fitting

I fitted and aligned the main gear brackets to the wing spar and used a pilot drill guide made from a piece of 3/16 choke cable sleeve per the manual, this worked quite well.

The main gear leg struts are very hard steel and I used cobalt drill bits and a makeshift jig to drill first a 1/8 pilot hole and then the 5/16 final hole. Each pilot hole took 45 minutes and the final hole 30 minutes using low RPM and plenty of cutting fluid. The photo below shows the drill jig and the "bullet" used to align the final hole with the pilot hole.

The welded brackets are not an exact fit to the fuselage sides and will require thick shims, next challenge is to find some 8-10mm alum bar or plate to fabricate some tapered shims to fill the gap between the weldment and the fuselage skin.

I'm glad this step is done, it is a critical area and the parts are expensive and in the case of the wing spars, essentially (for me) irreplaceable!

Default Wings On Wings Off

It's a canoe!
Wings On, to fit the main gear, Wings Off again to be able to continue with riveting on the central belly skins. Reminds me of "Wax On, Wax Off", the lesson is the same...

Not only did my wife make me an RV cake when it was my birthday, but she also helped to buck those rivets that I couldn't reach on my own (quite a lot), how lucky am I! We used just about every bucking bar to reach all the rivets.

The next step is to remove the canoe from the jig and start fitting the top skins. This jig previously helped to build a RV-4, now it's also done my -6A, though there's probably no further use for it. That's a pity, as the Oregon is now so well seasoned.

I also spent a bit of time away from the RV (still RV related) maintaining and fertilising the farm strip for spring. It is helping to keep me motivated.

thanks for the update Paul. Guess there are quite a few of us here following your progress, always refreshing to hear from your build!
And a lovely shot of that beautiful motivation strip

PS
Congrats to Rosie as well, hope she ain't stuck in there
