Design and development
The RemSchetMash Robust is the only aircraft built to date by this general manufacturing company. It has a high wing of constant chord, without
tricycle undercarriage is mounted on the fuselage with spring steel cantilever legs bearing the mainwheels. The rear underside of the fuselage tapers upwards to the tail, where a constant chord tailplane carries a single piece elevator between two endplate fins. The fins and rudders are parallel edged but with rounded tips, the rudders noticeably less deep than the fins.[1]
The Robust is powered by a
Hirth 2703 twin-cylinder in-line two-stroke engine, driving a three-blade propeller via reduction gearing.[1]
The prototype Robust, serial LA-0872, first flew in 2006. As with some other Ukrainian ultralights, e.g. the
Volkswagen 2300 engine.[1]
