The servo is an important component of your radio-controlled (RC) vehicle. These small electronic devices house a series of gears used to rotate a single servo arm 360 degrees. A servo is generally responsible for steering the RC, though nitro powered vehicle's also require them for operating the engine. Learn how to test the functionality of your servo to ensure they are operating at full capacity.

Plug a fully charged battery into the receiver and plug the servo into the first channel input on the receiver. Turn on your transmitter.
Use the steering wheel on the transmitter to send signals to the servo. Turn the wheel all the way left, then all the way right, while watching the movements of the servo.
Check that the servo can rotate all the way in both directions. Turn and hold the wheel to check that the servo can maintain its position without a glitch or vibration. If the servo does glitch, check to see if the connector is firmly installed in the receiver; if it is properly connected, your servo is faulty and needs to be replaced.
