I installed a 3 channel TQ 2.4 Ghz onto Emaxx. Here is problem when I turn it locks up and the receiver blinks green, I then lift up truck and wiggle wheels and it will go back to centre position. I also installed heavier 2075 servos, had 2 but as per someone suggestion only 1 is required, same issue either way. Servo is center correctly not sure the problem??

I took a video of this, hope someone can help.
