Well balanced propellers reduce the vibrations in the copter and the noise in the sensors, improving the stability of the Crazyflie. In most cases there is no need to balance the propellers, but if you want to do it this is how it’s done.
- A small round pin or needle
- Tape. Normal transparent office tape works well
- A pair of scissors
Start by checking if the propeller is well balanced. Do this by placing a propeller on a needle. Hold the propeller in a horizontal position and then release it. If it tilts over, it is unbalanced. Balance the propeller by attaching a small piece of tape on the side that is pointing upwards.
If the propeller is unbalanced, attach tape to the convex side of the propeller as shown in the video. The amount of tape that should be used varies and you might need some tries to find the correct amount.
