Avia BH-7A & BH-7B

The Avia BH-7, constructed in Czechoslovakia in 1923, was an experimental fighter plane.

It featured a parasol wing monoplane configuration and was developed alongside the BH-6 as an alternative option.

Both aircraft shared the same fuselage and tail design.

Unfortunately, the BH-7 encountered several severe crashes during its testing phase, resulting in its abandonment as a fighter aircraft.

Nevertheless, Avia persevered and repurposed the design for a racing plane.

The revised model, known as the BH-7B, underwent modifications such as reducing the wingspan by 1.4 meters (4 feet 7 inches), integrating the wing directly onto the fuselage, and eliminating the cabane struts.

On the other hand, the original fighter version was designated as the BH-7A.
