Flight characteristics were found to be good with the exception of poor yaw control at low speeds.
The rear motor can be tilted laterally via a servo to provide yaw control.
If a 6 rotor aircraft loses power to one rotor it will lose yaw control.
A series of disc brakes controlled differential speeds between the two rotors, allowing yaw control.
From 1998 onwards however, Active yaw control was no longer available with manual transmission.
A yaw control, the Electronic Stability Program, is optional to help prevent fishtailing.
The rudder projected below the boom into the jet efflux and provided yaw control even when the aircraft was stationary.
The rudder pedals provide yaw control, and the throttle controls engine power.
The vertical surfaces are made in a similar way and extend both above and below the wing, incorporating rudders for yaw control.
This was the first of the brothers' gliders to incorporate yaw control, and its design led directly to the 1903 Wright Flyer.
