Not that it had problems with low altitude to begin with, but it retains the epic stall speed of 60 and the great engine power, can go low to kill GA, go high to kill bombers, and can sweep bomber flights off two or three planes at a time before breaking off to cool those revolvers...it utterly smack fighters around too with that kind of firepower and accuracy of 20mms...
Didn't get ordnance for it though so I dunno about reload time, but that kind of firepower is better off used as interceptor...
