Already in 1934 she exhibited Avia in paris took place the model aerodynamically improved B-534. Features on this model above were then used on the prototype B-634, which first flew in July 1936. Despite the shape near with B-534 it was basically a new aircraft. The wings had the same span, the upper wing but it was sitting lower and had much greater depth, the bottom should have less depth, changed was the shape of the arches end, and the chassis was replaced by a samonosným, with kapotovanými low-pressure tyres. The cabin was open, the back was against the early versions of the B-534 higher. Different was the armament - in the hull were left two machine guns, but were moved above the engine, and the development of the engine HS 12Ycrs allowed to use the cannon Hispano, firing hollow shaft.

The disappointment came in the form of performances, which were better, but not so much in order to be worthwhile to interfere in the already ongoing production. The blame was mainly increased weight, which is offset by better aerodynamics of the machine. Later, the prototype was rebuilt, got covered cabin matching B-534.IV, took over from her, also the undercarriage wheels and the spur. Avia already at that time focused more on the development of its own jednoplošného fighters of the future , and this machine so he could finish the tests kanonové loadout for [url=https://www.valka.cz/topic/view/1159/Avia-Bk-534]Bk-534..
