A few changes and suggestions to planes in general
AP4C → BR5
Its just plain better then the FW A8 also at BR5,more 20mm ammo,infinitely faster turn speed,much more controlable and responsive,and many rockets that easily wipe points.
F4U-4,BR 4 fighter
Version of the AP4 with 50 cals instead of 20mms (and you get a higher number of guns too),would have two 500 pound bombs (more then the BF 109 G6’s payload at the same BR)
All FW190 variants go down 1 BR
The armaments are not very great to make up for the abhorrant preformance of the series.horrible turn speed,terrible handling,and not very great of an armament,if any,to show for it.reducing the BRs would be good as they wouldn’t be OP but they could have better value at slightly lower BRs.
G.55 → BR 2/3
This may come with some controversy,but it has a less powerful forward armament then either of the P51 variants and much is slower at 660 Kph while the P51s have around 720 Kph.It also has much less explosives then the D and only slightly more then the C.for that reason it could easily fit in BR 2-3.
BF109 G10 and 14 gets 4x 50kg bombs and G6 gets 2x rockets
This would give use to the G10 and 14 after enemy planes are dealt with,and would give the G6 a much appreciated buff,especially since the F4u-u would be the same BR and the rockets would help make up for the difference in bombload.
B5N2 → BR2
No guns,slow,and fragile with a smaller payload then contemporary veichles,it belongs at BR2.
D4Y1 → BR2
A smaller payload then the dauntless and with much worse guns,absolutely no reason this should be at B
Yak 9T → BR3
Its overtiered at BR4,it should be BR3 like the Yak 9K,which has a better cannon.
