Quick question. I have a DR1...got it about 6 months ago. Had no problems for the few weeks I used it, then it sat in a storage box for several months until about a week ago. Battery charged up no problem. The left motor isn't turning. Everything else seems to be working fine, including the right motor. The wires from the left motor to the board are still connected.

Is the motor likely toast? If so, how do we get new motors?
