Why do the turret keep jerking when it rotates more than 90 degrees from the center line?
There are plenty of electronic wires connecting between the circuitry inside the turret and the hull, with excessive amount of rotation, the wires will get winded up and eventually cause damage. Therefore, the turret rotation is designed to stop at 90 degrees from the center line. The turret can rotate in leftward or rightward direction. ** center line refers to a virtual line being drawn from the front end to the rear end of the tank
