The EUT is powered by a 9V battery. The EUT has an ON/OFF switch, a control wheel, a control trigger, 3 trimmers, a control switch and a channel button. After switched ON the EUT, the control wheel is used to control the RC Car turning left and right directions. The control trigger is used to control the RC Car moving forward and backward. The steering trimmer is used to adjust the RC Car to go straight. The throttle trimmer is used to adjust the RC Car in idle when it is at rest. The steering radius trimmer is used to adjust the steering radius of the RC Car. The control switch is used to select the torque of the RC Car. The channel button is used to select the operation channel with the corresponding receiver. Totally, three channels are available for the user, different channels have different seri…
