 Avia BH-10

The Avia BH-10 was a single-seat aerobatic sports plane built in Czechoslovakia in 1924, based on the Avia BH-9, which was in turn developed from the BH-5 and BH-1.It was easily visually distinguished from the BH-9 by the tall anti-roll pylon added behind the open cockpit in order to protect the pilot in the event that the aircraft flipped over or crashed while inverted.
