just seeing you posted this, how long have you had it, as I am thinking they have a 30 day warranty on their items, don't quote me on that, but I know for a fact that any of their brushless set ups are only 30 darn days, so if your having issues, get emails out to them right away, and send them a few, not just one or two, as they seem to lack the customer service parts, hope it helps and don't wait
