These blades do have an asymmetrical airfoil and produce lift an angle of attack of 0 degree, enabling the pilot to decrease the flight rpm considerably, without losing any climb performances. The additional weight of the fuselage, lighting system and other mounting parts can be easily compensated for. The very low flow line combined with the more to the tip of the blade positioned center of gravity prove a very stable straight and level flight and optimized performance. These attributes are supporting the requirements of modern FBL Systems, for which these blades are optimized.

Needless to say, all blades are well balanced to function as one unit.
