Two piece, very light construction is precision CNC machined from Dur-alloy material. We designed this spinner to have internal-offset blade mounts. When flying with motor OFF, those features allow blades to retract flat against glider fuselage reducing air drag to minimum. This is very important because most flying time in electro-glider the motor is turned OFF and blades are folded. Spinner also have internal provisions for installing small rubber bands that help to keep blades folded tight against the fuselage pod all the time during flying when motor is turned OFF.
The spinner is nice shaped to complement many fuselage pods of the gliders and all around is enhancing gliders finale appearance. The spinner is suitable for Aeronaut and Graupner CAM blades.
