Re: "Backdriving" Motors -- Safe for Victors?

No need to worry here, the diode protection in the FETs provide a current path when the power is removed that routes the current to the input terminals of the Victor. This current will light up the LEDs on the Victors and will move the fans.
Although pushing the robot with the power off will not damage the Victors, you might be putting undue forces on the mechanical systems and wheels.
