The most recent changes to the drag model hurt the P-51s. Once upon a time, the P-51s could easily out-turn the P-47s and give the 109s a very hard time. Not anymore. Today, the flaps generate a great deal of drag. In terms of reducing the turn radius, the flaps are somewhat helpful, but at a huge price in turn rate and air speed.
I tell people to avoid using more that 3 notches of flaps. If you find yourself using more, invariably you will find yourself in a serious energy deficit in a fighter with only marginal acceleration.
I strongly suggest keeping the P-51 fast, limiting flap use and concentrating on its greatest assets, speed and flawless high-speed handling.
