These are both fighters at BR4, but they aren’t really enough for BR4.I propose that both of these be lowered to BR3,where they would fit better.below is my reasoning for the change.
Ki-61-II
This plane has a slow turn speed compared to other comparative Japanese planes at 17 seconds, and an armament not nearly enough for BR4, only two 100kg bombs, and two pairs of 20mms and 12.7mms, compare this to the corsair,and you can see quite a disparity in power
Ki-61-I
While this improves upon the TT version of the plane in turn speed, a good 14 seconds, but this time the 20mm cannons only have 120 rounds per gun,which as can be seen from the Zero (which has the same ammount of rounds), that is not enough, especially in high BRs where allied planes are very prevalent.
