Well I am a Frank Fan, I am also a N1K2-J fan but I hardely ever fly it, tooo dweaby, but then again I try very hard to stay away from those easy kill rides, spits, La-7 ect...
I would love to fly it and probably be labled a dweab for doing so but what the h!ll:)
I am almost 100% certain that No production Ki 84 entered service with the 30mm cannon as a standard feature, from all acounts I have seen save one(Buschells KI 84 book), this simply is not so, It is commonly held that he was in eror on this issue.
