    How many here own an E-AB airplane?

    How many are the builder on record?

    How many piloted the first flight?

    What airplane type?

    Yes
    Sorta, I helped build it along with many others.
    Used the factory test pilot.

    Curious. I’ve built and flown two airplanes. The first was a ground up restoration of a very modified PA-12 that was 95% new. The next was my very, very modified Cub derivative. I was thinking about the respective first flights. Very different. The experimental had a lot of unknown elements. I still seem to change something after every flight so I’m a test pilot every flight. It wears me out. It’s a different mindset than flying a known entity. I’m surprised there isn’t more discussion about the human part of experimental first flight experience. You know, that mixture of excitement to go and the resignation that something might not go right. A hightened sense of awareness is an understatement. At least for me.

    I'm the builder
    I did not make the first flight (completely different aircraft and I only had about 5 hours experience in)

    Completely different experience here. I built and fly an RV10, a highly evolved kit plane. In my thinking it as close to a ‘standard’ design as any certified craft, at least relative to first flights. No unknowns other than the quality of the build and preparation for first flight. Dozens of examples had been flown with the identical airframe, control system, and power plant. The avionics were somewhat unique but that has nothing to do with the initial flights.

    What I learned from my RC model days is that given a proven, or even a not so proven airframe design and power plant, if I got a very short list of things right before that test flight, all would go well. The short list includes CG, a working fuel system, and controls that are securely fastened and moving in the correct direction. Beyond that, if I was proficient on the controls, the test flight would be successful.

    So before that initial flight the CG would be very carefully checked. Anything outside of a certain range makes the plane unflyable. The edges of that same range will make it difficult to fly properly. The engine would be run and the plane would be tilted up to simulate a high angle climb, and then tilted and shaken every which way to see if the engine might stutter or quit due to lack of fuel. Then a last control check would be done with resistance on the surfaces and a last mental check that everything is moving the right way. Then go.

    The first flight of the RV10 was successful.

    Before the flight a problem was discovered by my tech advisor. All of my fuel fittings were only hand tightened (!!!)

    It took a few flights to discover that though the RV10 is extremely easy to fly, I had never been as stick and rudder proficient as I was on that day. Why? Because I had been flying my old Maule daily for the previous 6 weeks to get back and forth to the airport where I was doing the final assembly and flight. It didn’t hurt that the tail wheel Maule was a bit more challenging to fly well compared to the RV10.

    As a result I greased on every single landing of the ‘10 for the first 6 months or so. I’ve e since returned to earth and miss the occasional landing now days.

    But the ‘10 is really easy to fly.

    Many many times.
    More than I can count.

    I built and test flew the following:
    • Four star 40
    • Gentle Lady (2 actually)
    • Ugly Stik 40
    • Guillows Piper Tomahawk .049
    • Sig Cessna 172 w/ K&B Sportster 45 (Great engine)
    • Avistar 40 (Was built by someone else but I made the maiden flight)

    Let me know if you have any more questions about this. I am sort of an expert on the subject as you can see.

    Mine was the third or fourth of the type but had significant modifications to flaps, engine compartment, cowl, etc. I had enough airport to get it up over the runway and make sure the primary controls responded like they should with room to abort. They responded as expected. But this airplane is so different than other Cub types? My head was spinning. One of the guys on the ground reminded me right before I took off to just look outside and fly the airplane. Good advice. The G3X is too much to deal with on the first flight. Target airspeeds were unknown. All I wanted to see was engine temps and a skid ball. Some distant iPhone video from a friend.

    First takoff-
    First landing-

    Sorry if this is a silly question, but I noticed the PA-12 was a very popular plane in Alaska. I noticed a lot of them were very heavily modified. I thought a lot of the modifications would not be legal since it is a certified aircraft? Is that not true? (not that I care, but the PA-12 I was supposed to fly in Alaska with a family friend was heavily modified and it peaked my curiosity as to how legal the modifications were).

    Yes, the Wild at Cub looks a bit exotic but that’s the point isn’t it? I’m guessing that it’s a super STOL performer for fooling around in the outback or competing in short landing contests, yes?

    If you settled for an extra 200’ of runway you could just take a standard Super Cub and be done, no?

    Super STOL performer depends on the pilot. I'm not into contests or selfies. Just a family cruiser for an empty nester. 20 mph landing speed was a big draw. And the idea that I can land in a 650' semi-dry swamp behind my cabin. I can land my 180 easily in that distance but not in that location. The Wildcat is a mission built airplane.

    Alaskan PA-12s are usually modified to close the performance gap between a -12 and an -18. The one I built comes pretty darn close. Lots of mods. Many STCd. Some field approved. All legal. But Airframes is soon to have an STC 3-place airframe for the Supercub. That'll kill the highly modified PA-12 rebuilds. When you come down to the one mod that a -12 needs to be in the Supercub class? A change to the AOI, and you can't get an approval for that. With a 3-place Supercub airframe you won't need one. They already have an approved 4-place Supercub airframe so PA-14 rebuilds will decline, too, for the same reason.

    All three for me as well. Van's RV-9A. A proven airframe, but my particular RV-9A had never flown before, so it was a pucker moment to be sure!

    We are all a bunch of pansies compared to the guys who test flew airplanes back before CAD and FEA. Imagine being the test pilot of the Gee Bee...

    Several years back I spent a couple of hours with a former test pilot who test flew fighters. Crazy stories. He was killed a few years ago while instructing in a 182. Go figure.

    I have test flown 15 homebuilts so far two of witch I built. Also done 6 or 7 post restoration test flights on various airplanes. I have had a couple that were not pleasant and things could have gone to **** real fast. I do enjoy the challenge of taking an airplane on its first flight and I am very careful about inspecting everything before flying. Above all you have to be able to fly an airplane without thinking about it if you have to deal with any problems. I have a rebuild shop and do a lot of crash rebuilds and builder assistance on homebuilts and usually test fly the airplane when I'm done.
