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.
