It is not over modeled.
It is slow (besides the K4) but still slow, cannot dive at all, anything over 450 you can't move controls which males it extremely difficult to hold and keeo E. And not using the gondies makes the ammo pretty weak. It gets caught up too easily in furballs and is hard to escape the main fight.
It is not a high alt plane, so P51s and 190ds can dive all over it and still be able to run away. Most planes can catch the G-14 and less 109s on the deck. It is an easy plane to pick in the MA because it is not a BnZ style fighter and many players including myself give up E for a fight or a shot because we cannot extend like 190Ds or P51s can, which makes getting picked by others easy.
The views are difficult.
Just because it can kind of turn well and kind of perform decently in the MA does not mean it is over modeled.
It is really a moderate plane in the MA that does have great counterpunching abilities, which can make it deadly.
I actually think it is one of the more tougher groups of planes to learn and fly in the game because you have to be very skilled in defensive style evasives.
