This module is what you want. I had one in my Turnigy 9x which is the same TX rebadged.
If you intend doing longer range I would also get
this receiver as it is telemetry capable.
The transmitter module will start to beep if you get too far away.
I now have a Taranis so the module, the 9x and one rx may go up for sale.
I will keep the receivers and the original TX module though as they are compatible with the Taranis.
The original TX module binds to my WLToys micro quads and heli's.
I can also confirm that this mod is plug and play.
The only thing you may have to do to your existing models is redo your ESC calibration.
The opentx software available for these transmitters is a huge upgrade as far as customisation is concerned.
Although it comes with a huge learning curve, it is well worth it for the extra capabilities it adds to an already good tx.
