FC WINDSPOON propeller, resistant to heavy loads.
This propeller is simple, lightweight, robust, with a stainless steel leading
edge. It achieves high cruising speeds, but it is less efficient during
take-off. It is therefore not suitable for short grassland airports.
Sheet settings are more laborious. Recommended angle is 24º.
