Well, opened the rear loading hatch to look inside, at the antenna wire, It is connected to the board. Also took the back off of the transmitter and all wires look conected there too. Its either the transmitter or RX board making it run erratically. Either way I already emailed Mato to see about a replacement tank. I'd rather not spend any more time trying to troubleshoot it, when it should be running to begin with, its principle now.
