These blades are especially developed being used with flybarless systems. The angle between the longitudinal axis and the rotation axis of the blade is low supporting the straight and level stability. The torsion of the blade is high to prevent vibrations.

The angle between the longitudinal axis and the rotation axis is responsible for the maneuverability and agility in connection with the pitch responsibility of the helicopter.

The FBL blades are not reacting aggressively on pitch or other inputs, but it is stable during straight and level flight of the helicopter. The maneuverability of the helicopter, using the FBL system, will be adjusted within the electronic assistance system. Therefore for the electronical system a very stable straight and level flight is more important than the maneuverability, because using a FBL blade the system does need quite a lot less steering inputs than using another blade. These positive characteristics are also assisting the pilot who does not like to use the flybarless electronics but who are looking for a blade to support their helicopter`s stable flight and roaming maneuvering.
