The most fun I have with these airframes for RC Combat is with PAW .15s. The aluminum mounts beams are a little bit longer and a 4 oz tank mounts on the beams opposite the engine.
Matches last up to 20 minutes at speeds up to 60 mph.....[X(].
Mid airs are very easy to avoid and it's a lot like WWI dog fighting where you need to conserve energy and altitude. The PAWs even tend to sag a little with excess maneuvering, so you need to occassionaly level off before going on the attack again.
The biggest drawback to diesel combat is the streamers get soaked and hours of combat time will make you thirsty so make sure to have a lawn chair with a drink holder while flying those sorties.
