How to Drive a Futaba S3102 Servo Aircraft Control

The Futuba S3102 servo is made for radio-controlled airplanes and cars. The S3102 is an analog-style servo. Servos attach into the remote-controlled vehicle's receiver box and work in conjunction with the remote's transmitter to take in the signals and move the connected mechanisms in the airplane. Install and use the S3102 to help steer and "drive" your remote-controlled aircraft to smooth flights.

Things You'll Need

  • Four rubber grommets
  • Small hobby power drill and bits
  • Four metal grommets, same size as rubber grommets
  • RC transmitter control box

Instructions

    • 1

      Set the S3102 on a workbench and insert one rubber grommet into each of the four servo holes. Insert a metal grommet into the interior or each rubber grommet so that the wide end of the metal grommet makes contact with the servo tray in the aircraft.

    • 2

      Push the S3102 into the aircraft's servo tray and make sure the servo doesn't contact any part of the tray: Contact should be through the rubber grommets and the metal inserts. This protects the servo from the airplane's vibrations and extends the useful life of the device.

    • 3

      Mark the four servo-screw mounts to the sides of the servo tray, into which they get screwed to secure the servo to the aircraft's tray. The four screw mounts are on the outer edge of the S3102. Mark them with a fine-tipped marker.

    • 4

      Drill out the four marked holes and screw in the servo screws that come with the S3102 to secure the servo to the tray and airplane.

    • 5

      Connect the servo to the ailerons via the cables and plugs. Ailerons control the roll of the airplane, allowing it to move on the longitudinal axis. If you're using a four-channel transmitter, plug the servo cord into the "Channel 1" insert on the aircraft receiver. If you're using a five-channel transmitter, plug the first cable into the "Channel 1" plug and the second into the "Channel 5" plug.

    • 6

      Bring the aircraft into flight. On the control box, use the right-hand stick to control the S3102 servo's aileron prompts. Push the stick to the right to roll the aircraft to the right; push left for a left side roll. Take care to not roll 360 degrees with your aircraft unless it's an aerobatic plane.

    • 7

      Practice "dutch rolls" with the S3102 servo and the airplane. This is a move where the aircraft stays on the same horizontal axis but makes the plane roll right and left while flying. Push the right-hand stick back and forth to learn the nuances of the servo control.
