i will try not typecasting it when i get my battery recharged

Then it's either a defective speed controller or defective motor.. Try a lower value though. If you want proof, get a decent multimeter (Depending on the motor, it could be drawing 40+amps at 12v) and mesasure the voltage coming off the speed controller.

After you have tried everything else and are sure that the circuit breaker isn't tripping, (It produces a distinctive buzz and gets very warm>) then calibrate the speed contoller. It sounds like you might be on the hairy edge of being in the dead band (127 +/- 10). This is likely true if your joystick or pot input is sitting on the same table as the motor.

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.

Where are you putting this code? I am trying to figure out why you need this. or where you need this. I am still tryign grasp all of the aspects of the code since I only had about 2 weeks to look at it last year.

Thanks

thanks chris it turned out it was the motor. one of the brushes is loose and whne the motor runs in one direction it looses connection thanks alot
