The problem that some people have is that the A-20 in game is that it's capabilities in game sometimes don't mesh with reality. In real life, the A-20 was restricted from maneuvering like some pilots throw it around in game and they probably would like to see the same restrictions placed on it in real life be placed on it in game.
ack-ack
Make it realistic where if you pose unrestricted moves you break off parts off the aircraft. I agree, just because it was "tested" and could do a barrel roll, does not mean it was done in combat, more so i would see this as being completely restricted.
Actually I take it back, its a video game - things are going to be done in the video game that wern't done in real life, i.e you can barrel roll a B-17 in game. I would honestly oppose to a G-limit for the aircraft, that won't allow it going beyond that.
