McCandless M4


The McCandless M4 was a British single-seater ultra-light autogyro first flown in 1961. The original McCandless M4 was powered by a Triumph motor-cycle engine, this was later briefly replaced by a Norton motor-cycle engine which was abandoned in favour of a Volkswagen flat-four four-cylinder horizontally-opposed air-cooled engine which could be connected to the propeller without gears. The McCandless M4 had a cruising speed of 130km/h.
