Due to the complex nature of the 125B's internal workings and the amount of money you paid for it I would just send it back for a warrenty inspection. If not you are destined to ruin even more equipment trying to figure it out. Why take the chance? For a few $$$ you may have a completely reconditioned ready to go controlerthat is just as good as new. Better safe than sorry. None of us likes waiting, but patients is a virtue. Send them an email and let them know what you are experiencing, and let them tell you what to do. Most of the RC community companies seem to be pretty cooperative for the most part and they love working with us to make sure that we are happy with their products. So do what you know you have to do, and let them handle it.
