X9303 2.4 Service Bulletin

The JR Service Center has discovered that many of the X9303 2.4 transmitters have an issue in that the wires attached to the aileron potentiometer can come into contact with the voltage regulator that is mounted in the back of the transmitter. With repeated use it is possible that the insulation can wear through exposing the wire at the point that it contacts the regulator. It is recommended that the aileron potentiometer wires be rerouted per the following instructions and photographs. This notice does not affect XP9303 72 MHz transmitters.

Step 1. Remove the back of the transmitter case by removing the six Phillips head screws. This is illustrated on page G-14 of the X9303 2.4 manual if further instructions are needed.

Step 2. Inspect the aileron potentiometer wires for any damage.  If the insulation is worn and strands are broken or damaged return your system for service to the Horizon Service Center.

Step 3. Using a small Phillips screwdriver loosen the wire retainer that fastens the aileron potentiometer wires to the aileron gimbal frame.

Step 5. Place a very small amount of shoe goo adhesive on the wires to cover any worn wire insulation. Do not substitute any other adhesive type. If the wire damage is severe (worn through insulation, frayed wire, cut strands) please return the system for service.

Step 6. Reinstall the back of the transmitter case.
