No Actuators or Control Surfaces

Wings are pivoted by differential thrust from two electric props connected to each wing. No servos or actuators are required. Pitch, roll and yaw control is accomplished through a combination of differential thrust and wing pivoting.

Simple Construction

Airframe construction is as simple as two freely pivoting wings attached to a rotating hub. Each wing has two electric props to drive the wing forward, and to control the pitch of the wing. The concept may have as few a seven moving parts.

Vertical Takeoff

To perform a vertical takeoff, the wings position themselves in opposing directions, creating a two bladed helicopter rotor. The four electric props then drive the wings around a vertical axis, lifting the aircraft into the air.

Transitioning to Horizontal Flight

Once sufficient altitude has been gained, the wings begin to pitch downward until they are both pointing in the same direction, straight down. Then, they simply pitch up to enter into horizontal flight.

Horizontal, Fixed Wing Flight

While flying in fixed wing mode, thrust is created by the four electric props, which can be highly optimised for creating efficient thrust, since they never have to lift the aircraft or meet the demands of limited runway space.


Lift is created by the two large wings in both vertical and horizontal flight modes, meaning that the aircraft is always lifted efficiently. The four electric props never need to provide strong static thrust for lifting, so they can be optimised for efficient forward flight instead.


During vertical flight, the wings are able to alter their pitch quickly, at any point in the rotation cycle, giving them cyclic and collective control like a helicopter. During horizontal flight, the four electric props are able to provide precise pitch and yaw, while the pivoting wings enable roll.

Lightweight and Low Drag

In it’s simplest form, the Pivotwing has around seven moving parts and no actuators or transmission systems. This results in a lightweight, low drag airframe.

Nothing Wasted

Every component is used efficently in both vertical and horizontal flight modes.
