The TechProAviation Merlin HV 100 is a Czech amateur-built aircraft, designed and produced by TechProAviation of Olomouc. The aircraft is supplied as a kit for amateur construction.[1]
Design and development
The Merlin 100 features a cantilever high-wing, a single-seat enclosed open cockpit accessed via a single door on the fuselage righthand side, fixed tricycle landing gear with wheel pants and a single engine in tractor configuration.[1]
The aircraft is made from matched-hole drilled sheet aluminum. Its 7.8 m (25.6 ft) span wing has an area of 7.05 m2 (75.9 sq ft) and mounts flaps. The standard engine used is the 35 hp (26 kW) Verner JCV 360 twin cylinder four-stroke powerplant. Alternative engines include the 60 hp (45 kW) HKS 700E four-stroke, 50 hp (37 kW) Hirth F-23 and 64 hp (48 kW) Rotax 582 two-stroke powerplants. The aircraft will be marketed as a kit only.[1][2]
By mid-2011 only the prototype had flown, logging 100 hours of testing,[1] These tests led to modifications; by November 2012 the prototype had gained a fin fillet and the mainwheel legs were slightly forward raked.[3]
Operational history
By 2013 ten Merlins had been built. Flyaway prices, without tax, are engine dependent; the cheapest is the Verner-engined variant at €15,500 in 2015.[3]
