Here are some tips and tricks on how to improve how your Micro RC helicopter flies.
Twist the tail rotor – The micro helicopter tends to spin when the throttle is accelerated, sometimes bringing your heli to a hard landing. You can fix this problem by twisting the tail boom about 5 degrees to the left (when viewed from the rear). Twisting the tail boom is easier if you heat it up a little beforehand.
Put some weight to the main rotors - The sluggishness of the main rotors of the micro RC heli causes them to self stabilize when spinning. You can increase its stability by twisting a small amount of very thin wire over the outer rotor wire. Do this twice on opposite sides of one main rotor, and then do again for the other main rotor. As long as you don’t put too much weight on your micro heli this should improve your mini helicopter’s stability.
