DSMX (Input) to XBus (Output) Signal Converter Module.
This module will allow you to fly your JR Ninja 400 or other JR XBus compatible units such as the JR TAGS Mini on Spektrum radio. You will need two DSMX satellites with their connecting leads.
Note that even if you are using a DSM2 radio you will still need to use DSMX satellites. DSM2 satellites will not work with this converter.
