My planes run around in circles when I try to take off. I tried bending the wheels to compensate for the motor torque, but it didnt help. I have both tail dragger and nose wheel, neither has servo steering. How do you fix this?? Also I tried a flying wing with a edf-50 ducted fan , but it has so little thrust I can walk faster than it taxies. I tried changing the motor to a edf-55-150 and then to a edf55-300h, but still poor power. Are these cheap ducted fans just junk, or am I doing something wrong????
