Design and development

The Votec 252T is a side-by side seat development of MSW's earlier tandem seat Votec 322. The prototype, powered by a modified Lycoming IO-540-J3A5 flat-six engine, marries the wooden wings and empennage of the latter to a new, carbon fibre fuselage, though a carbon fibre wing is under development. All flying surfaces are straight tapered and square tipped, the wing low mounted and the tailplane located on the upper fuselage; the rudder extends down to the keel. The ailerons are balanced with external spades.[1]

The Votec 252T has a cabin over the wing, with baggage space behind the seat, under a single piece canopy. It has a fixed tricycle undercarriage with fuselage mounted cantilever legs and with speed fairings on all wheels. The nosewheel casters; there is a small tailskid for rudder protection.[1]

The first prototype flew on 26 June 2009. A second prototype with a 260 kW (350 hp) Lycoming AEIO-580 engine, redesignated the Votec 352T, is under development but had not flown by October 2011.[1]
