The ESC is located in a special covered bay that is contained within the battery compartment, beneath the battery hatch.
For LiteHawk CRUSHER MT and NOMAD ESC:
With the Battery Hatch removed, take note of how the wiring from the ESC is routed and the antenna wire hole before you remove it. Then remove the two screws from the ESC. storage hatch, and unplug the Servo Unit, and lift the hatch aside. The ESC. just lifts out, and unplugs from the motor.
