The offerded 3-blade folding propeller is a combination of professional carbon-blades H30K from Helix Carbon, an aluminium made hub and rubber springs. Helix designted this blades for up to 3.000 t/min turns. The typical working load is on 2.310 t/min and creates on 74,25 Nm 94 Kp thrust. In this condition is the over all load on the battery 16,7 KW. With its small pitch the propeller works best on aircrafts with les than 120 km/h airspeed. The propeller was well tested on Fresh-Breeze Monster (Hirth F33) and Rotexelectric Rex50. So it is the first choice for pilots, whose loking for an alternative for Scimitar 4-blade propeller or fixed 3-blade propellern for Geiger HPD, NT-Power or Rotexelectric engines. Because of the stronger H40K construction it also works fine with 20-25 KW petrol-engines inclusive Aixro-Wankel.
Flying with non rotating fixblade propeller is like driving with fixed handbrake !
