    Abstract: A vertical take-off and landing aircraft or drone that has at least two tilting propellers mounted in front of the center of gravity of the wing. These tilting propeller are actively controlled and are capable of providing pitch, roll and yaw control throughout the flight envelop. This method of control can be applied to tilt wing or teal sitter aircraft, conventional or flying wing as well as other wing configuration for example box wing. In hovering flight the wing would be in the vertical position. The tilting propeller would provide pitch and yaw control. Roll control would be provided by differential thrust of the propellers. As the aircraft transitions to forward flight pitch control would be provided by tilting propeller. While yaw and roll control would be provided by a combination of tilting propellers and differential thrust.
