Fast : 340+
Medium 315 +
Slow 290+
V.Slow 265+

Fast - Wing Loading - A 25 , B 31+Slats, E 34+Turbo, F if 370+, H if 360+, G otherwise
Medium - C 24, D 31
Slow - K 36
V.Slow - L 19, J 24

Conclusions:
D520 should be G not D.
A6M2 should be C* - add 90 degree turn.

Other A/C

Hayabusa I (not II) - C* but fragile no armour
Ki-27 - L
Fokker D.XXI - K
Buffalo I - K
F2A3 - D but fragile, no armour
Morane 406 - D (probably why the 520 was misplaced, 406 stats used)

I've deliberately missed out the I deck, as it's an "all dive bombers use this" situation. Neither speed nor wing loading makes any difference.
