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.
