I don't have combat film of it, but a 152 can essentially flip 180 and fly backwards. I will post film of it later.
I've been curious what the RV-8 can do in AH, but I can't remember how to enable it offline.
I've tried it in the RV8 and the most I can do is something like what that guy with the stache was doing in the red plane. Not a complete nose flipping situation more of a flat spin nose pivot.
