Avia BH-22

The Avia BH-22 was a trainer aircraft built in Czechoslovakia in 1925, based on the BH-21 fighter. The overall weight was reduced, while the structure was strengthened overall to allow for aerobatics. The weapons of the BH-21 were deleted and replaced by a camera gun. The type saw long service as a special aerobatic trainer and eventually several examples found their way into Czechoslovakia's aero clubs.
