Design
The Pottier P.40 was the first of Jean Pottier's many designs, begun around 1967, though not the first to fly as the P.70 flew in August 1974. Construction of the P.40 by Bela Nogrady was started in 1968 but the first flight was not made until 1975.The P.40 is a tailless aircraft with a swept, cantilever, low wing. In plan, the wing has a rectangular centre section and straight tapered outer panels with elevons. There are wing tip fins and outward opening rudders which extend a little below the wing.
The short fuselage is flat sided, mostly occupied by a long canopy over the single seat cockpit. The engine, a Volkswagen 1.2 litre air-cooled flat-four, is in the rear in pusher configuration. The P.40 has a low, fixed, faired bicycle undercarriage.
