[Mr. Lim]

Calibrating your Victors may help as well.

It sounds like your Victor centre-points are different from each other.

You can check to see if they're out of calibration with each other by measuring the voltage being applied to each motor when running. They should be close.

Hold down the reset button until the LED beings flashing red and green. Apply PWM signal full-forward, then full-backwards, then neutral. Wait for the LEDs to stop flashing.
