OVERVIEW

The Graupner 3D RACE COPTER propellers have been designed specifically for the new 3D generation multirotors like the Graupner Alpha 300Q 3D Copter. To achieve 3D flight with a multirotor a specially designed propeller is needed to be able to fly inverted with the same performance as during regular flight. The Graupner 3D RACE COPTER propellers have a fully symmetrical blade design and neutral blade geometry. This guarantees identical performance when rotational direction of the propeller is changed during flight.

FEATURES

  • Optimized for multirotor 3D flight
  • Symmetrical blade design
  • Low weight for better performance
  • Made out of glass reinforced polyamide
  • Available in different sizes and colors

INCLUDES

  • Set of four propellers (2X R/CW and 2X L/CCW)
