ok so as you have read the lefttrack on my heng long tiger 1 wont move forward. i havecheckthe wires to the motor and in i'm not getting voltage in forward but i am getting voltage when i move the track reverse.allthe wires on the circuit boards look fine no burn marks or frayed wires.i dont have much to work with because i am a soldier deployed to afghanistan and was trying to have my tank to play with. please anything would help even wire schematics because i am an aircraft electrian. i think its either the transmitter or the receiver board. thanks to all for the help.
