A lot of work has been done trying to get the awesome CX-10 to work with other transmitters, since its stock TX leaves much to be desired. I have a Taranis transmitter, which has a JR-type module for other protocol support, and so my goal was to build a JR module, based on an Arduino, that would do the protocol conversion between the PPM output of the Taranis, and the SPI input of the CX-10 RF chip. My focus was to support the version of CX-10 that has a GREEN PCB for both transmitter and quadcopter.

I did some research, and came across a thread with a lot of good info on the CX-10 protocol:

Great stuff. I did some research of my own as well. I saw that a few folks tried to get the CX-10 working using an NRF24L01 RF chip, but it seems like no one was successful, as the register set appeared not to be 100% compatible with the chip used in the CX-10 controller (XN297). I decided that the only way to go was to use the XN297 itself, so I carefully removed just the small PCB area that contains the XN297 and its associated components. I had to remove the left joystick first, which was a challenge due to the number of pins, and it particular those tied to the ground plane. Once the joystick was removed, I carefully cut out the PCB section. I used a coping saw for the vertical cuts, and a dremel for the horizontal cuts. The dremel caused enough vibration that the crystal connected to the RF chip broke off due to metal...Continue Reading

Here's a diagram I put together showing my separates connections. I had to put the switch for the tail ESC to get it to arm properly:
1 - Plug in battery with tail ESC power off
2 - Let Gyro, main ESC initialize
3 - Move rudder stick to left, turn on tail ESC
