Hold the phone brothers! This guy (me) was just a grunt helper that did some tig welding on a plane motor frame! The real builder is my nephew! I just help when I can, or give any mechanical help when asked. Which ain’t very often. My nephew, the young man actually doing the build, has a pretty level head on him, and patience in spades. Prob why we mesh so good, I can mess with an invention or mechanical idea forever till I finally get it like I want it. He’s also doing this the “Johnny Cash Cadillac” way. As he gets extra money from side gigs, play money, he spends it on plane stuff. So it may take him a little longer since he doesn’t want to go in any debt on any of it. Doing it the way he’s doing it, plus saving money in multiple areas, he said he should be able to get er built for way less than what this plane usually would cost. For starters, the Yamaha engine was way cheaper than the Rotax usually ran in these planes. But it comes in lighter, is EFI, and bout twice the HP. But like I said, he’s gonna have it to where when he’s done building it, he’s done paying for it. Obviously outside of upkeep, etc. Good Huntin, and God Bless, Rusty

I think he said it puts out 160-180 hp (?), more if you wanted to juice it up, but it’ll have a gearbox on the output since the prop doesn’t need and won’t be rated for 10-15,000 RPM. Think it’s a 3.83-1 gearbox. Course the plane doesn’t weigh nothing, like less than a 1000 lbs w/full (50 gallons) fuel. I believe he said he can “cruise speed” at 150 mph. I may be off on some of my specs, so I’m not 100% on all I’m telling ya. But I’m texting him now to make sure I ain’t out in left field on anything. Cuz I am getting old as he’s pointed out a time or two. Good Huntin, and God Bless, Rusty

Forgot to put this one in the other day. After I left that day he did get the running gear installed. Now at least he can pivot the plane around to different spots. I helped him set it on a sawhorse that he put right at the firewall/where the motor frame bolted. I grabbed the frame and just picked it straight up while he slid the sawhorse under it. Granted, it was balanced on a pivot point, but still amazing how easy it was to pick the whole front of the plane up by myself high enough to get it under there.
