Avia BH-12

The Avia BH-12 was a two-seat sport aircraft built in Czechoslovakia in 1924, the final development of the Avia BH-9 family that had its roots in Avia's first aircraft design, the BH-1. It was a low-wing, braced monoplane intended for sports flying, and featured a redesigned wing that could be folded to allow the aircraft to be towed by road. The wing pivoted around its spar and then folded back, flat against the fuselage sides.
