The asymmetrical airfoil does have a reduced drag coefficient combined with an increased lift factor which supports the overall trend to reproduce as many details as possible in the scale area, this will, of course, increase the weight of the model. The blade itself has been designed with the center of gravity close to the tip and a small angular difference between the longitudinal axis and the rotation axis. These attributes grant smooth and stable flight characteristics during straight and level flights. The low net weight of the blade is reducing steering and mechanical forces, increasing the flight time considerably.
These blades have been developed in cooperation with the Helifactory using their helis to reach the upmost performance.
