The Rolandas Kalinauskas RK-7 Orange (also called the Muse, Fly and Bite) is a Lithuanian ultralight aircraft, designed and produced by Rolandas Kalinauskas, of Prienai.
The aircraft is supplied as a kit for amateur construction or as a complete ready-to-fly-aircraft and has been noted for its very low price.
[1][2] A simplified single-seat version of the Rolandas Kalinauskas RK-6 Magic, the RK-7 was designed to comply with the Fédération Aéronautique Internationale microlight rules.
It features a strut-braced high wing, a single-seat enclosed cockpit under a bubble canopy, fixed tricycle landing gear and a single engine in pusher configuration.
The tail surfaces are built up from aluminum tubing, strut-braced, covered in Dacron sailcloth and protected with a small tailskid.
