Why don't you give them an se5a model aircraft bomber? Just make it a little bigger, after all the se5a is the biggest plane in dogfight. You can make their own designs on the plane, like W U D F on wat up dog fights! For mbizzi, same thing.
Maybe the German bomber can be one of the mention before. The rear gun could have....say 300 ammo rounds, does that sound fair? The front would probably get more action so we could say 450 rounds of ammo? Same thing for both bombers.
I don't know if this is a good idea to you guys, I was just thinking
The bombers could travel the same speed as the fighter planes would without a bomb, because they have more power.
Maybe one of the Aces would like a plane that goes on water? That would be pretty cool. See you in the skies,
