Bauer’s BAD-12 Gyrotrainer is a two-seater very much in the Magni style, but it has some interesting features of its own. A tailwheel allows the pilot to climb out steeply with confidence and the downward kink of the tailboom gives clearance for a generously sized prop. Power comes from a Rotax 912S, a Rotax 914 or a Subaru. A fully enclosed version, the Gyrotrainer C (for Cabine), is also offered.
The Bauer BAD-12 Gyrotrainer is a Czech autogyro, designed and produced by Bauer Avion of Prague. The aircraft is supplied as a complete ready-to-fly-aircraft.

The turbocharged 115 hp (86 kW) Rotax 914 and Subaru EJ22 are optional engines.
