Do you have indication that the controller is working? Does it beep in reverse? Do you hear the click from the solenoid when you attempt to start moving? If you think it might be the controller, the company FSIP (Flight Systems Industrial Products) is the only certified Curtis repair facility. I blew up my controller and sent it to them. They fixed it in under a week for way cheaper than any other option! They will also inspect it for you.
