If you're doing this again, might I suggest that the aircraft of choice be something different....
Like: Stuka, SBD, and D3a1 Val.... Ever had a dogfight in a stuka? It's ugly, ungainly, and hard to fly but it can actually pull a few moves. The SBD and Val are rather decent as well (the cowl mounted guns help a lot).
And you could have a runner-up prize if the winning pilot had a steady rear gunner the whole time LOL (reward the team not just the pilot).
