Trainer – Programmable Trainer System
H-44
The X9303 2.4 contains a Trainer System that allows 
the instructor to transfer some or all of the primary 
flight control functions (Throttle, Aileron, Elevator and 
Rudder) to the student. It also allows for indicating if 
the transmitter is to be the Master (controlled by the 
instructor) or Slave (controlled by the student). The 
Trainer (TRN) switch is used to transfer control to the 
student when the X9303 2.4 is being used as the Master/
Instructor transmitter.
1. Connect the Trainer cord between the Master and 
Slave transmitters. Turn the power on to the Master 
transmitter (the Slave transmitter remains powered off 
and can even have the module removed).
2. Make sure the Slave transmitter is in the PPM/FM 
modulation mode. If the slave system is a X9303 2.4 
or any other system that is Spread Spectrum only, 
such as other JR 2.4GHz systems or Spektrum brand 
systems, this does not apply.
3. Highlight and select Trainer in the FUNCTION LIST 
to obtain the Trainer Display.
4. If the X9303 2.4 is being used as the Master transmitter 
(the transmitter operated by the instructor), select 
the channel(s) that are to be operated by the Slave 
transmitter (transmitter operated by the student) when 
the trainer switch is depressed.

When all channel selectors are in the MAST position, 
NORMAL appears on the display and all 4 channels 
are transferred to the student when the trainer 
switch is depressed. 
If only certain channels are to be transferred to the 
student, highlight and select the channels that are to be 
transferred, moving the indicator for these channels to 
the SLAV position for these channels. When less than all 
channels are selected as SLAV, PROGRAM T appears on 
the display indicating that the Trainer System has been 
programmed to transfer only selected channels.
The X9303 2.4 is now ready to be used as the Master 
or instructor transmitter. Pull the TRN switch forward 
to transfer control to the student. Control will remain 
transferred until the TRN switch is released.
