It sounds like you need some good old fashioned debugging, since one part is obviously not working right.
1. Try different values for your pwm output (i.e. hook it up to a joystick input). If it works for different values, try calibrating the victor
2. Try running the victor without a motor attached, if it works the motor is screwy
3. Try a different victor, if it works then the first victor is screwy
4. Try it on a different pwm output, if it works you either have a logic error or a broken RC.

You don't necessarily need to do them in that order, typically start with the easiest one to test. That would be disconnecting the motor.
