Design and development
The Votec 221 is a single seat, low wing monoplane, designed for engines in the power range 90-180 kW (120-240 hp). The first prototype, completed in 2009, has a 157 kW (210 hp) Lycoming AEIO-390 flat-four engine and the second, finished the following year, a 134 kW (180 hp) engine. MSW's numerical designation has two digits indicating power in hp/10, followed by the number of seats, suggesting an optimum 220 hp power unit.[1]
Externally, the Votec 221 resembles a scaled down (span, 80%) MSW Votec 351. It has low aspect ratio straight tapered wings with blunt, almost square tips. Ailerons are assisted by external spades. The empennage is also straight tapered, with a forward set tailplane mounted on top of the fuselage, far enough forward on the fin to require only a small cut-out for movement of the deep rudder. Both elevators have trim tabs and the rudder is horn balanced. The cockpit, placed over the wing, is covered with a single piece, starboard hinged canopy. Like the Votec 351, the 321 has a conventional undercarriage. The mainwheels are mounted on curved, sprung cantilever legs and enclosed by long fairings. It has a steerable tailwheel on a long cantilever.[1]
Operational history
The first prototype is Swiss-registered and the second German, the latter appearing at Aero 2011, held at Friedrichshafen that April.[1] First flight dates were not released by late 2011 but the first prototype was certainly flying by late May 2012.[2] A full scale non-flying mock up has also been exhibited.[1]
