Speeds mil/wep OTD with 100% fuel. Old models like the G-6 and Spit 9 are in for refrence and weapon changes noted.
F-4 310/332 (no gondola option now)
G-2 320/339 (unchanged)
G-6 316/336 (no 30mm option now)
G-14 316/345 (20 or 30mm and gondola options)
K-4 337/367 (old G-10 with only 30mm option, no gondolas)
Spit5b 289/303 (12+ boost, 60 RPG for 20mm)
Seafire 289/303 (12+ boost, 120 RPG for 20mm)
Spit8 310/337 (no .50 cal option)
Spit9 310/321 (no .50 cal option)
Spit16 315/342 (.50 cal, no .303 option)
Basically with the Spits what we get is the old AHI Spit V but with only 60 round per gun for the Hispanos. This is a very early SpitV, but the Seafire is now the same as the AHI SpitVc with 12+ boost and 120 RPG in the Hispanos.
With the 109's the K-4 is the old G-10 with no gondolas or 20mm spinner option. The G-14 is the same as the old G-6 (20mm, or 30mm and gondolas) but with considerably better speed with WEP. The new G-6 performance is unchanged, but there is no longer a 30mm spinner option. The G-2 and F-4 are unchanged performance wise, but the F-4 loses its gondola option.
Looks like there can be some very interesting matchups for the CT in particular '41-'42 and '43-'44 ETO and N Africa.
