Ron, I think the easiest, and maybe fastest way to get this thing fixed, would be to remove the problem gear, and take it with you to some RC car hobby shops, and see if they can find something that matches diameter and teeth. That seems to be what others have done. Remember, this is not rocket science, nor is it museum restoration. From what I have read, you may have to do some modification of the shaft part of the gear to make it fit right, but, at least you will have a radio that works.
