I know conventional wisdom says that you shouldnt stallfight the G-10, but I find that it turns quite well. It wont turn inside a Spit, but it can turn surprizingly well. I find that most planes that arent supposed to turn well can turn well enough to get the decisive advantage on the majority of folks who arent expecting it (NOBODY expects the Spanish Inqusition!!). I stallfight every plane in the inventory (even buffs) and I find they all have more harsh stall behavior than AHI, but it does not seem worse in any one particular plane.
This "turning in a plane that is not supposed to turn well" tactic only works against people that dont take risks, and it virtually never works against someone really on their game like Bug, Slash, Duke, Arlo, or most of JG54. They see it coming, and will take a risk, while most dont and get whacked.
