They are highly stable and resistant to deformation. The material is relatively lightweight, helping to improve the aircraft's speed and control. The propeller blades generate thrust by rotating, propelling the aircraft forward. The blade rotation speed controls the aircraft's speed. To use the RC propellers, simply insert each blade into the aircraft's rotor head. Ensure the blades are properly aligned and securely fastened to the rotor head nuts and bolts. Before using these RC propellers, carefully check the product's rotation diameter and pitch to ensure they are perfectly suited to your RC airplane motor. Due to external factors such as temperature, a final balance check is recommended before flight.
