If you are using gy401 it should not spin even when it it starting to lift off, just make sure that the red light is on and steady that means its on heading hold. if you cant make the light steady then your in trouble dont fly it. get an experience pilot to set it up. gy401's are very good gyro's you dont even have to trim the rudder it will compensate by itself to make the tail steady. no drifting no nothing steady like a rock even with a wind. trust me I have one on my caliber30 gy401 with 9254 servo.


cheap gyro's make your learning process a little bit harder because you are always moving the rudder stick going up to compensate any movement. trust me I have one of those cheap gyro's s
and they end up in the garbage.
