420mm Main Blades - RotorTech

RotorTech 420mm Ultimate Main Rotor 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 suit 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. Featuring 385mm of length, a 38mm wide chord, a 5mm Blade Root, and an inward-focused CG for excellent agility, and delayed stalled characteristics.

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.
