Yak bugs/inconsistencies?

[IceFire]

This is the "problem" with the Yak series being one of the first outside of the IL-2 to be modelled. They weren't done to the same standards that the planes that came later in the series were done.

They are legitimate issues but unlikely to be resolved. The Yak-1 in IL-2:BoS has none of these issues and you can lean over and have a look at whats left in the fuel gauges on the wings there.
