I have a 50 in a Somethin Extra with 13x3.75W prop. Hovers at half- 3/4 throttle. Plane is 6 pounds. The engine was the worst pain in the neck to break in I have ever seen. I thought I had it dialed in good, but everytime I go to fly it it either deadsticks or leans or richens out in the air.[

] The servos have problems too. A huge amount of differential on the elevator halves and the right aileron servo is wigging out. Power is enough, but not ballistic. Fun airplane, just got to get the bugs worked out!
PS: Funny thing is, I have like twenty airplanes and a heli, and NOT ONE of them works good enough to fly!
