TechProAviation Merlin 100 explained

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] [2]

Design and development

The Merlin 100 features a cantilever high-wing, a single-seat enclosed 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] [2]

The aircraft is made from matched-hole drilled sheet aluminum. Its 7.81NaN1 span wing has an area of 7.05m2 and mounts flaps. The standard engine used is the 350NaN0 Verner JCV 360 twin cylinder four-stroke powerplant. Alternative engines include the 600NaN0 HKS 700E four-stroke, 500NaN0 Hirth F-23 and 640NaN0 Rotax 582 two-stroke powerplants. The aircraft will be marketed as a kit only.[1] [2] [3]

By mid-2011 only the prototype had flown, logging 100 hours of testing, These tests led to modifications; by November 2012 the prototype had gained a fin fillet and the mainwheel legs were slightly forward raked.[4]

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.[4]
