Ensuring that your RC helicopters rotor blades track properly is just as important as blade balancing. This article will show you how to quickly and easily balance your RC helicopter’s rotor blades so that they track properly through the air.

RC helicopter blades are balanced along their vertical axis before flight, but they can still travel through the air in a less than optimal path. If the rotor blades have slightly different shapes, then each blade will try to follow a different path while spinning. You can check to see if your RC helicopter’s rotor blades are tracking properly by following this procedure:

1. Get a friend that is willing to help you balance your model.
2. Mark one rotor tip with bright adhesive tape.
3. Have your friend hold the transmitter, while you hold the model so that the rotor blades are at eye level.
4. Be careful not to hold the blades too close to your face, and have your friend increase throttle to full.
5. Watch the rotor blades edge on. If you only see one profile, then they are tracking correctly. If you see two then they will have to be corrected.

Fortunately, there is a simple and cost effective way to fix badly tracking rotor blades. If you have a collective pitch helicopter, then you should be able to adjust the pitch of each rotor blade. A fixed pitch RC helicopter can be balanced by adding tape between the top surface of the rotor blade and the root holder. You can also try gently flexing one rotor blade to increase the camber of its airfoil.
