Avia BH-7

The Avia BH-7 was a prototype fighter aircraft built in Czechoslovakia in 1923.

It was a parasol wing monoplane developed in tandem with, and as an alternative to the BH-6, which shared its fuselage and tail design.

Like the BH-6, the BH-7 was involved in a number of serious crashes during its test programme, which led to its abandonment as a fighter.

Undaunted, however, Avia used the design as the basis for a racing aircraft, shortening the wingspan by 1.4 m (4 ft 7 in), fairing the wing directly onto the top of the fuselage and dispensing with the cabane struts.

This revised version was designated BH-7B and the fighter as the BH-7A.
