I have knocked up 3 missions as follows:-
1 pure dogfight on the NW Europe map. 3 bases each, blue have Stukas on the bomber base and 109F4s on the fighter bases. Red have IL2 field mods on the bomber base and P39's on the fighter bases. Bomber bases have lots of static aircraft and are around 15 minutes flying time apart. Objective is to destroy your opponents bomber base 100%. All bases have AAA. Teams will have to balance number of fighters to bombers and whether to defend the bomber base or escort their bombers attacking the other side.
The other 2 missions are more like Mike and Gadje's 6v6 machine matches - hope they are not copyright

First is F4F3 v Zero, second is P51D v 190A9. Teams air start co-alt at 2000m and around 5 minutes flying time apart. 8 seats per team made up of 4 pairs which will have some separation when you spawn. Winning team is the last one to have at least one plane in the air.
