A single-seat single-engined flex-wing aircraft with conventional three-axis control. Rogallo wing. Undercarriage has three wheels in tricycle formation; no suspension on any wheels. Push-right go-right nosewheel steering connected to yaw control. No brakes. Aluminium-tube trike unit, without pod. Engine mounted below wing driving pusher propeller.
This experimental machine is an attempt to mate three-axis controls to a Rogallo wing. It uses the same power pack as the TR1 MkII trike unit, plus a modified Sabre wing. The trike unit is fixed to the wing structure rather than being suspended from it, and the wing is mounted much lower than the normal hang-point of a trike.
No test flights have been carried out on this aircraft by 1982.
