Merlin HV 100 is a single seat high-wing ultra-light aircraft. The fuselage of this all-metal plane is of a semi-monocoque construction with vertical structural members and longitudinal stringers. The front fuselage, from the firewall to the rear of the cockpit consists of a riveted aluminium alloy tub. The door is top-hinged, supported by a gas strut in the open position.
Merlin's wings as well as the tail surfaces are fully aluminium skinned. The aircraft has a fixed tricycle undercarriage with two moulded composite cantilever main legs and a steel tube steerable and telescopic noseleg.
The aircraft is powered by the two cylinder two-stroke Rotax 582 with 65 horsepower. The reliable engine is fitted with a three blade ground-adjustable DMP1 composite propeller.
