The RK-6 was designed to comply with the Fédération Aéronautique Internationale microlight rules. It features a strut-braced high wing, a tandem two-seat enclosed cockpit under a bubble canopy, fixed tricycle landing gear and a single engine in pusher configuration.[1] [2]
The aircraft forward fuselage is made from welded steel with a wooden laminate covering in the cockpit area, with the tailboom made from aluminum tube. The tail surfaces are built up from aluminum tubing, strut-braced and covered in Dacron sailcloth. The wings are wooden, produced by Arvydas Vaicekauskas and equipped with Junkers-style flaperons with flap deflections of 20 and 40 degrees. Its 10.71NaN1 span wing has an area of 12.5m2. The standard engine available is the 640NaN0 Rotax 582 two-stroke powerplant. The aircraft can be flown without the canopy fitted, if desired.[1] [2] [3]
