First flight of RV-10 N284MA, 3/16/2026

After 4.5 years and 3200 hr of buliding, N284MA had it's first flight yesterday! Other than the oil door popping open on takeoff and high CHT on Cylinder 1, it was a good flight. Flew for 30 min at 4500 ft to assist with break in, did some slow flight to check handling, then came back to land. I did my transition training last year with Alex De Dominicis and the last bit of landing practice last Friday really helped. First I want to thank my wife Melissa who believed in me, helped me with hundreds of hours of riveting, and encouraged me to keep going when I got frustrated. I also want to thank my friend Kurt Rutkowski who was at the hangar almost every day the past few months as I finished up the build and prepped for flight. His experience was invaluable.

The airplane flew great, no trim or rigging issues that I can tell so far. There are a few squawks I need to address before the next flight: 1) Stiffen up the oil door (I used 2 of the Cessna style latches), 2) re-check the nose breakout torque as there was a bit of shimmy at high speeds, and 3) consider cutting down the dam in front of Cyl 1 to see if I can improve the temperatures.

Although I haven't posted much, I've read thousands of posts on VAF and pretty much every question I had during the build was already answered here. Thanks Doug for hosting such a great forum and everyone else for particpating!

Regarding your shimmy, check all three tires to make sure they are round and in balance. We had a shimmy and I thought it was the nose gear. I landed once where some friends witnessed the landing and they said it was the main gear hopping up and down. I checked the main tires and they were way out of round. I think the stock tires are not the best and when they sat for a few years they took a set.

Congrats... Enjoy Phase 1

I’ll have someone watch it during a taxi- thanks for the suggestion! I did notice that pulling back on the stick didn’t seem to help the shimmy.

Well done Bob,
Welcome to an amazing story....
Please share some panel / interior p[hotos when able.
 
Just finished Flight 2. Used some speed tape over the oil door for now, worked great. I removed the dam in front of Cyl 1 and temps were much better with no apparent negative effect on 3 and 5, they’re all within 20 deg or so. Checked the nose breakout torque and it was fine, did not observe any shimmy today on rollout.
There was however a loud clunk that I felt in my feet when pulling a bit of Gs to get back up to altitude at one point. I heard something similar again later when I nosed over to descend, sounded like a seat belt rattling outside against the skin (but not of course). One of my ballast weights in the baggage compartment was a bit loose and could have shifted 0.25 inches or so which would explain the first clunk but not the second one. Any ideas? Backfire from being too rich? Nothing loose under the cowl or externally as far as I can tell.

I think I found the source of the rattle- the plastic FAB and fuel pump drain lines were still a bit long. I cut them off closer to the clamp and didn’t notice the sound on Flight 3 yesterday.
I do have a heavy wing though, it requires full R aileron trim to fly level. I’ll go through Van’s troubleshooting guide and see where that goes.

Left wing is heavy?

Watzlavick,
Great.
It is a monumental achievement to build a plane and fly it.
Glad you had support and a mentor/helper.
Others reading your post will also be encouraged to continue the process.
Safe phase 1.

Left wing is heavy?
Yes, it appears that way. I should clarify my previous comment- it takes full R aileron trim to fly level hands free, there is plenty of aileron authority. On of the QB wings, I think it was the L one, the aileron hinge line wasn’t parallel with the flap hinge line, the OB edge of the aileron was about 3/16 higher than it should have been. The lower skin was clecoed in place while riveting so not sure what went wrong there. I adjusted the wingtip TE to align with the aileron which in turn was rigged with the flaps in reflex. From reading posts, I may have to adjust the OB aileron bracket.

Before doing anything labor intensive or complex, do the simple stuff. Is the weight evenly distributed left to right? You are a large chunk of ballast. Similar fuel in both tanks? Have you a similar weight in the right seat? Vans does have heavy wing guidance that I found helpful.

And congrats! I am building a 10 and there are many challenging moments to get to where you are.
