I too have ahd increased performance from missing flaps but it was a long time ago.
Here a pic of my boston fron a TOD with no elevators, engine or left aileron. I lost the right one soon after as well as rudder and it still flew, only u couldnt point it any where. The only thing that took me out of the sky was a zeke:)
Ps u can see bombs dropping on a field and i actually took out radar:D
