How Do I Perfectly Balance & Track My RC Heli?
It is important to balance and track an RC (radio-controlled) heli before the model helicopter’s first flight. Out-of-balance blades can cause vibration of the helicopter and lead to drift during flight. A perfectly balanced heli will waste less energy and fly longer. You can balance an RC heli with some blade-balancing tape or electrical tape. Use an Allen key to remove the bolt that holds the RC blade. Place the RC heli rotor blade on a sharp line such as the edge of a pocket knife blade. Maneuver the heli blade until it is balanced on the edge of the knife. This is the way to find the center of gravity, or CG. Once the center of gravity is found, mark it with a pen or tiny piece of tape. Repeat this process to find and mark the CG for the second rotor blade. Place the rotor blades on top of each other and run a screw or bolt through the main holes. If the CG marks align, they are matched perfectly. If they are not matched, place a small piece of tape on the blade that has its CG the
