The RemSchetMash Robust is the only aircraft built to date by this general manufacturing company. It has a high wing of constant chord, without flaps. The wings are braced by single struts to the lower fuselage. This is a carbon fibre monocoque with a starboard side door for access to the single seat cockpit. A conventional 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 German 41 kW (55 hp) 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, eg the Lilienthal Bekas, agricultural spraying was seen as a possible role but no further aircraft appear to have been built.[1][2] An enlarged version, the RSM-25 Bekas, has been considered. This would have a span increased to 11.40 m (37 ft 5 in), a maximum take-off weight of 495 kg (1,091 lb) and be powered by a 60 kW (80 hp) Volkswagen 2300 engine.[1]
