The Mainair Demon Microlight is a single-seat, single-engined flexible wing aircraft with weight-shift control, manufactured by Mainair Sports Ltd. of Rochdale, Lancashire. The museum’s example was sold in 1982. The wingspan is 32 feet and the maximum take-off weight is 370lb. The pilot is suspended below the wing in a tricycle unit using a bar to control pitch and yaw/roll. A 22hp Robin engine is mounted on the tricycle unit with a pusher propeller. The maximum cruising speed is 35mph and the take-off and landing distances are less than 150 feet.
The tricycle unit and wing are easily folded to be carried on a car roof rack and this aircraft is characteristic of the simplest type of portable, low-weight, low-cost microlight aircraft.
