    The thing I haven't seen mentioned is ease of repair. Stits, Ceconite/dope, Stewart, are all easy to make repairs if they're not top coated. As soon as you topcoat them with enamel or urethane,...

    I've heard of pre-oilers on aircraft. But you don't need an accumulator for high g turns because unlike in a car where the lateral acceleration throws the oil to the side of the pan, away from the...

    It can be done, but... With a bike engine, you'll have to design and build a reduction drive, or build a prop adapter and use elements of the bike gearbox. Either way is not a simple thing. Also...

    I filled my Kolb by pressurizing a 5 gallon gas can with a foot pump (the kind made for air mattresses). I did some measuring, and a sealed gas can ballooning up in the summer sun gets up around...

    So the gap gets narrower after the test period, not surprisingly. What's interesting is the rise in accidents after 40 hours... plane is sold, or the owner starts flying to new places.

    It would be interesting to compare statistics for only homebuilts operating in phase II, to weed out the early test failures, but I doubt there's any data on that.

    Regarding the Ercoupe, I have no...

    Another thing to consider is that many low volume parts are repurposed from something else, I.e. it may be that the P-39 gear handle may have been adapted from a standard socket wrench speed handle,...

    Right, but only if it's on the list of preventative maintenance items that the pilot/owner is allowed to do.

    2-stroke engines generally use slide carburetors that don't have a butterfly. The slide is in close contact with the carb body so it should get good heat transfer.

    The commercially available electric carb heat systems I've seen for Rotax (or any engine with a Bing carburetor, I guess) sandwich the electric heater between the carb and the manifold, so it heats...

    I assume you mean you're building an E-AB that meets LSA specs, because if you're building an LSA kit you have to set it up exactly per the plans.

    On an experimental I'm pretty sure there's no...

    100LL occasionally won't do any harm, on a steady diet of it you might see lead fouling of plugs or valves. I ran straight 100LL in the Mosler half VW in my Fisher with no problems for the 100...

    Nice video!

    That's the kind of flight that makes the previous 95 forum pages of tribulations worth it, eh?

    People often hire an A&P to do a prebuy inspection when they can't be there themself. The problem is finding an A&P who knows anything about ultralight construction or 2-stroke engines.

    Funny, I've never felt the need for goggles in any of the open cockpit aircraft I've owned. I've tried them just to see what it was like, didn't like the tunnel vision. Even in completely open (no...

    If the sound is good, like a a big radial engine ship taking off, I agree with those folks. But for airborne videos when all you'd hear is wind noise mixed with the steady drone of a modern engine,...

    I never had much trouble starting them, either, if they don't start you're either doing something wrong, usually flooding it, too much fuel, or it's a bad glow plug.

    Glow fuel is mainly methanol...

    Don't rule out a used homebuilt, you can often get much better performance for the same amount of money and maintenance can be a lot less expensive.
