Thanks. I'll try your custom curve settings when I get a chance. Although, the Spit is one of the few DCS planes I have applied any curve to. I think I have it set at 20 right now on my CH Fighterstick. It was way too sensitive without it, but then too much seemed to affect the responsiveness, which is the only thing going for this bird, in my estimation.
As for the wheel brakes, I've tried the slider on the fighterstick, and a button. But right now I've cheated a little bit and set both of the toe brakes on my rudder pedals as the brake levers.
