Avia 50-MP

The pillar also mounted the pusher configuration 19 kW (25 hp) Poinsard flat twin engine, its cylinders exposed for air-cooling and driving a 1.6 m (5 ft 3 in) two bladed propeller just behind the wing trailing edge.

[3] The pilot's single, open cockpit was immediately in front of the wing-mounting pillar in an oval section forward fuselage similar to those of the motorless gliders.

The position of the propeller disc just behind the wing required the rear fuselage to be rather shallow, so it was formed by four longerons with plywood covering, resulting in a rectangular section.

The empennage was conventional, with a triangular tailplane sitting on a low, raised step with a curved leading edge and carrying straight tapered, square tipped, unbalanced elevators.

The earliest design had always included the possibility of an alternative wheeled undercarriage[3] and by June 1934, just a month after the first tests, it had been fitted.
