Flight Designs 440ST

The machine has been developed by Flight Designs, an associate of Pioneer Internation-al Corporation and the firm which builds and sells the single-seat Jetwing ATV, as well as conducting a research programme on a prototype single-seat three-axis machine de-signated 440ST However, at the start of 1983, Andrew N Bohjalian, group president, announced that production and sales of the FlightStar would be taken over by a new associate company called Pioneer Interna-tional Aircraft. The Pioneer group is well known for its activities in aerospace industry, and includes the Pioneer Parachute Company, which is one of the world leaders in its field. So it is not surprising to find that the FlightStar has been designed from the start to accommodate an emergency 29.0 ft diameter (8.84 m) parachute, which is deployed ballistically and fitted behind the pilot at the rear of the frame.
The aircraft is sold as a complete kit requiring 20 h for assembly and at a price of $7495 in 1983. Apart from the parachute, options offered are floats, skis, wheel fairings, electric starter for the Kawasaki TA440A engine, larger diameter wheels (16 and 20 inch, 41 and 51 cm), transport covers and an instrument panel.

The Flight Designs 440 ST was a single-seat single-engined high-wing mono-plane with conventional three-axis control. Wing has unswept leading edge, swept forward trailing edge and tapering chord; two-fin tail. Pitch control by elevator on tail; yaw control by fin-mounted rudders; roll control by spoilers; control inputs through stick for pitch/roll and pedals for yaw. Wing braced from above by kingpost and cables, from below by cables. Undercarriage has three wheels in tricycle formation. Aluminium-tube framework, without pod. Engine mounted at wing height driving pusher propeller.

This single-seat twin-boom, twin-rudder aircraft exists only as a prototype in 1982, and was being used at Flight Designs to study the flight envelope of such machines.

Single-seat single-engined high-wing monoplane with conventional three-axis control. Wing has unswept leading edge, swept forward trailing edge and tapering chord; con-ventional tail. Pitch control by elevator on tail; yaw control by fin-mounted rudder; roll control by full-span ailerons; control inputs through stick for pitch/roll and pedals for yaw. Wing braced from below by struts; wing profile; double-surface. Undercarriage has three wheels in tricycle formation, with additional tailskid; bungee suspension on all wheels. Flush-right go-right nosewheel steering connected to yaw control. Aluminium-tube framework, with optional pod. Engine mounted at wing height driving tractor propeller.

Shown at Oshkosh in August 1982, the prototype FlightStar made its first flights during that summer. It carried trapezoidal planform ailerons, whose chord tapered toward the wing tips and which covered a little less than the full span of each wing, but these have been replaced for the production machines by full-span ailerons. In addition, the production FlightStar, on show at Sun 'n' Fun in Lakeland, Florida in March 1983, was fitted with a glassfibre pod with a windscreen mounted on top and going right up to the strut carrying the wing.
