firebirdt1

Side-by-side two-seat single-engined high-wing monoplane with conventional three-axis control. Wing has swept back leading and trailing edges, and constant chord; no tail, canard wing. Pitch control by fully flying canard; yaw control by tip rudders; roll control by spoilers; control inputs through stick for pitch/roll and pedals for yaw. Wing braced from below by struts; wing profile; double-surface. Undercarriage has four wheels in 'tricycle' formation; suspension on all wheels. No ground steering. Brakes on all wheels. Aluminium-tube framework, without pod. Engine mounted below wing driving pusher propeller.
Easily distinguishable from other Fledge derivatives by its unusual double nosewheel, the T1 is basically a two-seat version of the M1. It was first shown at the Aero 83 Exhibition at Friedrichshafen in March 1983 and was placarded as having made its first flights the month before. The standard version includes electric start, while options include wheel fairings and floats.
