Which Module?
The 9XR Pro accepts almost any make of transmitter module of the JR shape. If you already have a JR format module and a number of receivers, they will operate perfectly well with the 9XR Pro. Some modules need a little tape to make them a snug fit. Others need to be inserted carefully to avoid bending the pins.
The receivers you use must match the module. To bind the receiver to the transmitter follow the manufacturer's instructions.
You have two main choices of module at this time:
FrSky, either DJT or XJT. The DJT supports the older V8 series receivers plus D-series (telemetry) receivers. The XJT supports D-series and V8-II receivers, plus the newer
X series receivers.DSM2/DSMX: The OrangeRX module supports both protocols.
In addition, a module using the DSM protocol and providing telemetry is expected soon.
The remarkable capabilities of Ersky9x firmware, including powerful mixing, large model memory, flexible radio setup, voice announcements, haptic feedback, communication with your computer and Eepskye will be available no matter what brand of module you use.
