UPDATE!
So....this mind boggling issue has had me searching for answers for the past few days. I tried to run the tank a few hours ago and as part of my frustration, I was being a little harsher than normal with the Tx. All of a sudden....the right motor kicks in!!!!! It was the Tx just as Craig had suggested. Now, I can recreate the problem which is a huge step.
Im going to open up the Tx again and do more cleaning. One thing I noticed is that these new Tx's use exposed wiper's like what would be inside a potentiometer. Im going to shoot some contact cleaner in there. The joysticks engage a sprocket that in turn engages the wiper. The wiper moves across the contact surface (again exposed) and sends the signal to move. I havent taken apart higher end Tx's but I cant imagine they are anything near as cheaply made. This thing is flimsy and toyish and not touch sensitive at all.Obviously VStank spent much of their capex in creating an incredibly detailed and aesthetically beautiful tank. Anyway....looks like problem solved...for now.
CORRECTION!
OK guys...Im back! I thought the Tx was the issue but I actually found the real culprit today. While I was running it this morning, I realized the front headlamp was not working. So I decided to go inside the tank again to figure that out. I fixed it and when I was testing it, the right track goes out again....here we go again!! To make a long story short, the connector next to the lamp connector had a false contact. While moving the lamp connector (in<span style="color: rgb(255, 0, 0);"> RED</span>), I grazed the connector next to it with my finger (in <span style="color: rgb(0, 255, 0);">GREEN</span>) and the right front motor came on. Wiggled the cable around and the motor would go on and off. BINGO!!!!! It was a bad contact specifically on the middle black wire of the green connector in the picture.
FINALLY!!!! Now I can get back to enjoying my King Tiger!!!!
