The Kortenbach & Rauh Kora 1 was an unusual twin boom, pusher configuration motor glider, designed and built in Germany in the 1970s and intended as a training aircraft.
The overall layout was unusual, with a central pod fuselage in front of a pusher configuration engine and with its empennage on twin tail booms.
The central pod was broad, housing a cockpit 1,200 mm (47 in) wide under a starboard-side opening, two piece canopy which reached from the wing leading edge almost to the nose.
Instructor and pupil sat side-by-side, with the 48 kW (64 hp) Limbach SL 1700EC1 air cooled flat four piston engine behind them, where the wing became broader to allow propeller clearance.
The second prototype, which flew in 1976, retained the retractable nosewheel but had fixed, spatted mainwheels on thin, cantilever, spring steel legs mounted on the lower fuselage to save weight and reduce complexity.
