wrote: Gee, now I kind of wonder _why_ it stalled on takeoff. Obviously not a lack of power. Anybody want to take a wild guess at the wing loading? There's no wonder in that, it got too slow. And as heavy as that plane is, the stall speed is higher. It weighs in 500lbs heavier than a stock Glasair 3. That would definitely raise the stall speed. A stock Glasair 3 should wiegh in the neighborhood of 1,600lbs empty. The articals I read about Jawbreaker listed it's empty weight at 2100lbs. Book empty weight is 1550#, Wing area is 81.3 ft^2 for the standard wing and 91.5 ft ^ 2 with the factory extensions and stall is just shy of 80 mph. Wing loading is just shy of 30# per ft^2 and 27.3 with the factory wing tip extensions. Add 500# more for 6.1# ft^2 and that makes 36# per ft^2 wing loading. The stock 30# per ft^2 can make for an interesting rate of descent. :-)) That would be 33.4 # fit^2 with the tip extensions. Whether a plane stalls at 50 mph or a 100 is no real biggie if you expect it. If it was,no one would be flying twins and jets. As to more HP? At very slow speeds, or high angles of attack, HP is not always your friend unless you have the control surfaces and handeling characteristics to ... well, handle it.
