Set Up an RC Electric Race Car
If you're looking for a radio-controlled car with unlimited opportunity for fine-tuning, upgrading and complete customization, then you want a model you can build from the ground up. RC cars offer the fun and excitement of race driving, without the hassle of difficult labor and expensive parts. However, to ensure you're properly equipped to handle any malfunction you may encounter, it's important to familiarize yourself by learning set up your electric RC.
Instructions
Putting It All Together
1. Test the system before you mount anything to the chassis; connect the Electronic Speed Control (ESC) to the battery, using the matching clips already attached. This device is used to control throttle and needs calibrating to function properly.
2. Connect the positive and negative wires between the ESC and the motor. Red (+) and black (-) are a standard with most electronics; however, some manufacturers may use blue (+) and yellow (-) wires with their products. Refer to the user's manual if you are unsure about anything, since mismatching polarities may damage your hardware.
3. Plug the ESC into the first channel on the receiver; this connector is a small black tab with three wires (red, black and white) leading out of it.
4. Turn the ESC on while holding down the set-up button. A green flashing light indicates the device has entered set-up mode. Hold down the throttle joystick on the transmitter, and press the set-up button a second time. The green light should turn red, at which point you will repeat the same process-however, this time you are establishing full reverse/full brake, depending on your ESC's capabilities. Press the button a third time to exit set-up mode.
5. Test the system by holding the motor and applying some throttle. See if the light on the ESC turns green with throttle, and red when the brake is applied. Even though some ESCs may offer a reverse function, both the brakes and reverse are generally indicated by a red light, since both are opposite forces to forward throttle.
Mount Everything to the Chassis
6. Disconnect the electronics and use the screwdriver to mount the motor to the chassis. Slip the pinion gear onto the motor shaft, and tighten it with the Allen wrench. Pinch the sheet of paper between the pinion gear and the spur gear, and tighten the motor mount firmly in place.
7. Wipe everything down with rubbing alcohol and cotton balls. Cut two inch-long pieces of double-sided tape and stick the exposed side to the back of the receiver and the ESC. Find a location on the chassis that does not interfere with any moving parts. Peel the remaining part of the tape and affix both components firmly to the vehicle.
8. Turn on the power and reconnect the steering servo; once the trim is centered with the transmitter, mount the servo to the vehicle with the screwdriver, attaching it to the steering mechanism of the car.
9. Slip the fully charged battery into the car and attach it to the ESC. Check that all of your connections are functioning, and test that the settings are tuned appropriately.
10. Drive the RC slowly to make any last adjustments to the steering trim. Once everything is finished, use the wire ties to organize the wires, which will prevent any snagging while you're driving.
