Abstract: A VTOL aircraft, preferably of the swept wing design. An arrangement of propellors and motors are individually housed within ducts which are mounted within a wing. Each individual motor support arm will run from the motor it is supporting, through the duct wall and into the wing and will be attached to a central frame structure housed in the fuselage. Covers are provided over the ducts, operable by motor means such as a servo. When the aircraft is relying on the internally housed propellors to provide lift, the covers will be open to allow air to pass through the ducts. When the aircraft is relying on airflow over the wings to provide lift these covers can be closed to provide uninterrupted airflow over the wings. The covers are designed to match the surface contour of the wing when closed.
