MCR-01 stands for Michael Colomban Revolution –(series) 01, a carbon-based evolution of the Colomban MC100. When first designed and produced marketing was aimed at the plans-built community. It was successful in Europe. Manufactured by American Ghiles Aircraft as the Lafayetti 4S, it uses the Rotax 912S or 914 engine. The wing and fuselage skin is made from layers of kevlar and carbon-fibre sandwich, with the control surfaces constructed from foam ribs supported by carbon spars and fused to an aluminium skin. Fitted with a constant-speed prop, almost ¾ span double slotted Fowler flaps, and of composite construction. First flown in 1996, the MCR 01 ULM employed double slotted flaperons, but it was soon discarded for separate flap and aileron. For details of the four variants, click here.
