First, ditch those right handed kit-provided joysticks if you are using them. Second, calibrate the Victors with some other joysticks (preferable the old CH flightsticks). Third, perhaps try making your program such that the maximum PWM value is attained before the joystick reaches full travel. Fourth, check for binding, friction, and misalignment in your drive system. Noise/sound is often a good indicator.
