I suppose it is because the only flyable plane in the AXIS planeset is the BF-110.
The BF-109E unlike the real one, is too unbalanced compared to the SPIT-I whose bad negative G performances are the only real differences with the BF-109E, while in the real, the BF-109E was faster, more powered, a faster diver, and a better climber than SPIT-I and last but not least it was heavily armed.
Those caracteristics i found in Warbirds 2.77R3 planeset (even if other performances didn't correspond to the respective real probably)
I heard someone to say about ALLIES planeset that, it was made by Americans and then suited for Americans.
I have seen even some planeset made by Russians and suited only for Russians (in a different simulator). Anyway often programmes implementing a game exceedes overmodelling theyrs country planes.
Was I clear enough ?
This is the main reason so few pilots prefer LW Aircrafts (I know to be hopeles over Malta but......W ITALIA
)
C u all in the skyes around Malta.
