About a million years ago I was building custom tube guitar amps using all the old Fender circuits as a basis. Anyway, I used forstner bits to cut the socket and potentiometer shaft holes in 16 and 14 gauge aluminum chassis. Even the plain high speed steel forstner bits held up great in 5054 aluminum. Much better than cutting some hardwoods like teak and beech. Drill press and lots of lubricant. Rapid Tap Aluminum lube.
Don't you need a type rating for a jet?? I know for a pure jet you do but I'm not sure it extends to turbo prop. Soooooooo. On top of fuel burn and initial outlay you have to develop a syllabus for a type rating and get it approved by the Feds?
Brian and Carol Carpenter flew a Quicksilver with a 447 for 450 hours without a teardown or incident. With oil injection! Yours is also already registered. And you have a trailer too. Hmmmm. I'm at 5000' and it's been 85F at 6AM around here.
I guess the problem with Airdale is the lack of communication. A public post explaining the situation would be better than dead silence. I think you're right though Leni, none of these one man shops make it. I'm thinking Sky Raider, Ridgerunner, Airdale, and hundreds of others that are just a memory. The Buttercup guy is selling plans and somebody else is making fuselages. The Skyote folks are doing it piecemeal too. If the Airdale guy would farm some stuff out maybe at least repairs could be made. But nobody will make any money, that's for sure.
https://spokane.craigslist.org/search/sss?query=SkyRaider I need to go see this one. Anybody want to go? I'm in Reno NV and would need to trailer it back. The engine was bought new for the kit then run a few times ( taxi only of course ) and then has sat around for 16 years. I imagine the tanks should be cleaned, hoses changed, carb confronted, tires checked and general quality assessed. The current owner is the original builder and the airplane is not an airplane yet. No N# no registration. I'll need to talk to my local FAA mech dude and see if he'll call it parts. I know it's not an AvidFox but it would never have existed without Avid as the inspiration. Ship the engine off to Rotax Rick, put a starter and electrical system in it and I'll finally be back in the air.
You back in the sandbox again? Probably can't say eh. Anyway, High Country is Nick Lappos who took his MKiV from Cal to Conn. I would like to see that build thread if somebody can find it. Otherwise maybe a PM to exchange e-mails or text messages with Robert Hast.
