Controls are pushrod-actuated and have electrically powered servo tabs on the ailerons and rudder. The ailerons, elevators and rudder were metal structures with fabric covering. They were fitted with Frise ailerons and slotted flaps. Its wing was all fabric covered wood, except for steel tubing flaps and ailerons. The ailerons and flaps were similarly the same part. The trapezoidal ailerons are near the wingtips. A type of aircraft control surface that combines the functions of both flaps and ailerons. The flap/ailerons gave yaw control when hovering. The B.1 had four elevators (inboard) and four ailerons (outboard). A single centre stick controls the ailerons and elevators. Roll is controlled by movable sections on the trailing edge of the wings called ailerons. Two-segment outboard ailerons for low speed roll control. Some aircraft are equipped with "flaperons", which are more commonly called "inboard ailerons". The future of aircraft design, however, lay with rigid wings, ailerons and rear control surfaces. Agility was enhanced by installing ailerons on both wings.
