Asymmetrical rotor blades are increasing the efficiency considerably. Due to the asymmetrical profile the lift is increased and the drag reduced, therefore the flight endurance is increased up to 100 %. The use of these blades is recommended to pilots not interested in 3 D flights, for pilots who just want to have fun and for beginners.

They are also well suited for Flybarless systems
