Avis II

As the Avis I showed poor performance, the designer, prof. Abody-Anderlik were prompted to redesign the aircraft in spite of the decision taken by the Légüyi Hivatal of purchasing 21 Fiat Cr.20bis fighter airplanes from Italy.

The design held to the Jupiter VI engine and, as redesigned it featured a slimmer, slab-sided fuselage as well as redesigned vertical tail surfaces. It also featured narrower interplace bracing struts and an increased gap.
The overall empty weight was reduced by 100kg and, after some initial testing the engine was enclosed within a Townend ring.
It was flight tested in 1935 but it turned to overweight and it wasn't as agile as other contemporary two-winged foreign fighters. It was to be armed with two 7.62mm Gebauer machine guns but the development was abandoned in favour of the Avis III. Unfortunately we haven't found any blueprint or side-drawing of it, so it remains undrawn.
