I'm not sure if this is a regular issue with bombers in general or with the new B-25 and its flight model, but I'm trying to have a formation of four B-25s at 6000m flying at 400kph. After several minutes of flying it looks like the wingmen bombers start stalling while staying in formation and just fall out of the formation tumbling several thousand feet. Some recover, and others don't.
I've tried adjusting their speeds, altitudes, formation settings, etc, but they keep falling out of formation. Is this a regular thing with bombers and if so is there something I need to do in the editor to prevent this?
