RE: GP Super Stearman
Can't help you on gas engines. I have a Saito 1.80 with onboard glow tied to the throttle. i use a Spektrum 2.4 7 ch system, and it seems to work great.even with the onboard glow, and the mods on the pilot (turns his head with the rudder) my plane came in at less than 15 lbs. and I added NO lead to balance it.
