Having Problems....Need Help!
 

I recently blew up the first reciever i had laying around and went out to buy a new ESC. I bought a Novak XRS sport reversable for 4-7 cells and a 15 turn motor limit. I connected everything but had to hard wire it and voided the warranty. So It seemed to work ok until i turned the steering completely to the left or right and the truck would no longer move. When i would only apply a small amount of steering the truck would run normal. So, I am able to steer and run the truck but when i lock out the steering the ESC will no longer respond. I dont know if it is the reciever or ESC or the Servo. If anyone has any imput i would greatly appreciate it.
THanks:?

The servo is a JR racing Z9000T ultra high torque digital.... and the reciever is a futaba fp-r122je 2 channel am.
