Stahl 922 help

Ok, tried that. When rudder is turned left one track goes forward and one goes backward, when turned right the tracks turn opposite. But when I move throttle up or down, nothing happens.

As far as the pots, I only turned them about a quarter turn and then back to there original position. I'm starting to think there is a problem with the ESC, I switched the throttle and rudder for each other and still the steering works but no forward or reverse. The lights on the ESC come on and off when I move the stick for throttle but no track movement.
