Micro Biplane Aviation Micro-bipe


Single-seat single-engined biplane with con-ventional three-axis control. Wings have unswept leading and trailing edges, and constant chord; conventional tail. Pitch control by fully flying tail; yaw control by fully flying rudder; roll control by two-thirds-span ailerons on lower wing; control inputs through stick for pitch/roll and pedals for yaw. Wings braced by struts and cables; wing profile; 100% double-surface. Undercarriage has three wheels in tail-dragger formation with additional nosewheel; coil spring suspension on tailwheel, no suspension on nosewheel, and axle-flex suspension on main wheels. Push-right go-right tailwheel steering connected to yaw control; castoring nosewheel. No brakes. Aluminium-tube framework, without pod. Engine mounted between wings driving tractor propeller. Patented composite wing struc-ture using waterproof fabric covering with heat-set backing adhesive.
First shown late in 1981, the Tom Wright-designed Micro-Biplane, or Micro-Bipe as it quickly became known, created enormous interest after looping at the Long Marston fly-in in May 1982.
Although it was offered to the public as early as March 1982, the manufacturers were at that time in no position to satisfy the enormous interest that the tiny plane evoked and in May, many frustrated would-be cus-tomers later, the decision was taken not to go into production with the Micro-Bipe as it stood, but to refine it, 'productionise' it, and set up a company to make and market it. The aircraft developed into the Super Tiger Cub 440.
