History
As Czechoslovakia built its air arm in the early 1920s, Avia's designers Beneš and Hajn produced a series of progressively refined biplanes. The BH-4 was among the first in this lineage, providing a reliable training platform. It contributed to the development of Czechoslovakia's indigenous aircraft design capability.
Variants
The BH series progressed rapidly through BH-3, BH-4, BH-5, BH-7 etc.; each was a refinement rather than a major redesign.
Where you'll see it
Used by the Czechoslovak Air Force as a primary trainer in the early 1920s.
