Unless there is a good reason not to, such as the outer fuel tanks tend to catch on fire more often than the AUX tank, the filling order for the Mossie's fuel tanks ought to be changed to AUX, Inner, and Outer tanks, in that order, and draining to the inverse of that; Outer first, Inner second, AUX last.
The Aux tank is center- and forwardmost, so shifting the fuel there would improve both roll rate, and to a somewhat lesser degree, dogfight maneuvering stability.
