Description

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.
Rotortech “Ultimate” Blades are a unique design concept from the owners and factory pilots at Fun-Key. The RotorTech 420 Ultimate variant delivers increased performance across all metrics compared to other blades in this size. Improved thrust at equivalent collective pitch angles, longer flight times with better performance, higher rotational rates while maintaining stability and a linear feel, and an increased stall margin at comparable thrust levels.

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.
