I don't have the stall limiter on. That's why I'm thinking it's the prop model change, it's the only change I know of.
I'll compare power off departures after work, presumable they will be the same. I didn't compare fixed pitch props yet either.
So far the F4U-1A, P-47M, and Bf-109F, all behave differently at full power compared to AH2.
I'm not complaining about it, just curious.
