RotorTech blades are finely crafted premium carbon fiber rotor blades from Fun-Key Aeroplane Models. RotorTech blades are designed to be an all around powerful, efficient, well rounded performance oriented blade that will suite a large majority of flight styles from simple aerobatics, F3C, and extreme 3D flight. Additionally, RotorTech blades utilize a minimal amount of paint within the mold, while still providing excellent flight visibility. By using less weight on all of their blades, weight is saved on each set which offers a small boost in performance.
All RotorTech blades are precision balanced and matched at the factory, allowing pilots to bolt on and fly any set of RotorTech blades (main or tail) to their helicopter.
The 530mm main blades utilize a button cell battery for operation, which is included with the package! Simply take the blades out of the box, install the batteries, and go fly! No extra purchase is necessary for the 530mm main blades.
