A further development was the single-seat, single engine Drone of 1935. A lightly laden high wing monoplane of 40 ft span, the Drone was devised by Charles Herbet Lowe-Wylde by fitting a motor-cycle engine to his sailplane. The idea was to give cheap training to pilots who had already gone solo. The pusher engine was mounted on top of the wing, behind the cockpit. Two were produced and two conversion were made.

The BAC Drone was the production version of the Lowe-Wylde Planette and was first produced in 1933. B.A.C (1935) Ltd was formed in 1935 to take over production and development of the Drone.
