as it looks like the Team is overworking the westernfront fighter planes (Spit V, Spit IX'42, Fw190A-4 full boost , 109 series) perhaps it would be nice also to look on the american fighters there.
my "suggestions" would be:
- give the P-47D-22 the same performance as the D-27. So both can be used side by side if wanted. As it was in real btw. So it would be nice for a missiondesigner to choose betwenn a Razorback and a Bubbletop Thunderbolt without having differences in the Performance.
at the moment the D-10 and the D-22 are performing almost, if not at all, the same...... useless to have two Razorbacks in my opinioin.
-ad the armamant "aditional Ammo & Droptank"

-change the P-51D-20 to a 150octan boost version (like the Mustang III in comparison to the P-51C) and leave the P-51D-5 as it is.
and about the two Hellcats ( with the same performance), would it be too dangerous (Grumman wise......

) to change something already existend , like the F6F-5. To name it, to give it a better perfomance to have a 1944 Hellcat.
The two identical (beside the small windows

) F6F are, well, one is actially useless to have
