Thanks for posting the planeset Crash.
Looks like not everyone is happy though. Unless the guys are serious and we could try a Buffalo v Me-262 match
I dont think its too bad myself. Just that same number of choices should be available for both teams.
Seafire and Zero match up ok. The Seafire( low alt version)is faster low the Zero up high.
The Hellcat and Ki-100 too. The Yankee is faster high and the Japanese a bit faster below 3k. Although ammo advantage goes to the Ki big time

turn time is similar enough to make the difference down to pilot skill for both sets
The Ki-43 weighs the low fight too heavily for blue as it outturns everything and we all know the fight usually ends up low and slow.
The floatplane

Guess '=BgAF=Captain Birdseye' asked for that one?
I would suggest leaving out the last two and making it a Zero, Ki-100 v Seafire low, Hellcat match. Or find suitable matchups for red for the Ki-43 and the A6M-2.
Any other ideas FI ?
