Those Flying Machines Pegasus

tfm-pegasus
Pegasus I


Single-seat single-engined high-wing monoplane with hybrid control. Wing has swept back leading edge, and tapering chord; no tail, canard wing. Pitch control by elevator on canard; yaw control by tip rudders; no separate roll control; control inputs through weight-shift for pitch and tiller for yaw. Wing braced from above by kingpost and cables, from below by cables; wing profile; 30% double-surface. Undercarriage has three wheels in tricycle formation; no suspension on nosewheel and glass-fibre suspension on main wheels. Push-right go-right nosewheel steering independent from yaw control. No brakes. Aluminium-tube framwork without pod. Engine mounted below wing driving pusher propeller.

The Pegasus is a hybrid control machine, with the pilot in a swing seat connected to the elevator on the canard. A tiller arrangement sometimes called a yoke, operates tip rudders to give yaw control, with roll control by induced.
Pegasus comes in two forms, the Pegasus I with single-cylinder engine and the Pegasus II with a twin. For the single, there is only one engine option, the 215 cc Cuyuna 215 developing 20 hp, but Pegasus II buyers can choose from Kawasaki or Cuyuna twin cylinder units.

Options include hand and ballistically deployed parachutes, a strobe and - for the Kawasaki only - electric start. The company's main marketing effort was being directed toward the Pegasus II, which is listed at $4695 ready to fly in standard form in 1983.
