I wrote I library for jaguars and victors (though I haven't actually tried it with victors)
in header:
#include "Victor.h"
Victor mycontroller;
void setup()
mycontroller.SetPort(pinnum,true/false) //the boolean is for if its reversed or not.
void loop
mycontroller.Set(from -1 to 1)
this might only work on pin 3,5,6,11, like I said I haven't tried it because I don't own any victors. but if you want it here you go

, and you will probably have to recalibrate the controller.
