Forgot to mention that I had to reverse the positive & neg lead on the two wires coming from the right motor Before I did that the Tank would only go forward moving the right Tranmitter lever to the right. it was weird, but after checking I discoverd the in full forward position, one track went forward the other went in reverse . It is trckey to re-solder the connection at the motors so I cut the two leads and re-soldered them and used heat shrink tubing . Works great now , even the Barrel illiuminated and the machine gun fire with out the Barrel going ip & Down
