Rotor balancing

It is important to balance the rotors because disbalance will cause vibration when the rotors spin. This vibration can be strong enough bend the shaft, which will in turn increase vibration.

Sorting blades as described under "Mounting Blades" helps the balance. However, even small variations between blades and the amount of glue used to mount them may affect balance. If you have a prop balancer, use it. If not, hold the wing in your hand such that the shaft is horizontal and spin the rotor. Mark the lighter blade (the one that consistently ends up pointing up) and add a piece of tape to its tip, or smear some glue on it. Repeat until the rotor stops with random blades pointing up.
