RE: GP Super Stearman
WOW What a great plane. I flew mine this weekend for the first time. I use a Saito 1.80 and had to add ZERO weight!! It balanced perfectly without even installing the weight box. This is a gentle airplane that flys beautifully. It went together easily, and I am totally impressed. I used 4 servos in the wing, I know it is not scale, but it flys great, so I wont "Fix" it. Barbie fits perfectly in the rear cockpit, and looks much better than the bobsey twins that came with the airplane.
Good luck. If anyone is close, I will be glad to help.
