    I still think medical incapacitation is a lot more deadly on the freeway than in the pattern.

    Just helped a friend/student pick up a Cub. I looked at the struts - old, small fork, no U stamp. I said "these don't look sealed to me." Seller said "yes, they are." Misrepresentation? Were...

    Back to the "lower half" joke. I did laugh, but then I think that somebody took it seriously.

    The field approval would be for a J3C65. There is no difference between wood and metal spars. Problem is, you cannot simply use a field approval; you need the original installer or a new field...

    These are PA-11 spars. The holes seem to match the original Piper J-3 spars. I did not take precision measurements, since the ferrules were already pressed in.

    Yeah. At 500 feet, you either have to be in the process of taking off or landing, or very sure that you are 500 feet or better from the nearest ranch house or pickup truck.

    Well, I am replacing Dakota spars with Dakota spars. Before the wing got bent, it fit perfectly. I double checked the front spar, thinking I had to drill the fuel tank attach holes. Nope - already...

    I picked up a Champ several years ago - the guy said he used lightweight fabric. I almost panicked. To me, Stits always had glider cloth, intermediate 2.6 oz/yd (which I use) and heavy - 101, or...

    I think by definition Vx gives a better gradient than Vy. It is about 50% better in my Stroker J-3. Lifting off above liftoff speed may be good for jets, but it doesn't help with Cubs.

    Whatever else can be said about the “Ellis” Cubs, their fabric was beautiful - a work of art. I am tasked with supervising a repair - I will be trying to match 2003 Aerothane Cub Yellow.

    Will they do as with DPEs and have everybody go to OKC at their own expense, maybe even for yearly conferences? Will you have to flunk half the applications?

    I have seen folks regrind what looks to me to be very serviceable tappers and cams. I think, without any evidence, that regrinding removes something important.
