In this tutorial, I’ll show you how to replace the stock transmitter of your Turnigy 9x with a more advanced module by FrSky.
The FrSky module has many advantages:
[checklist]
- it can cover more distance
- it’s more robust in the presence of noise
- it can receive telemetry data
- it supports different rx modules
[/checklist]
On the Internet is available a receiver feature chart about the different receiver modules that also lists the compatibility between the rx and the tx modules.
I brought from Banggood the transmitter module and some receivers:
- FrSky DJT-JR 2.4GHz Transmitter Telemetry Module, tx module
- FrSky D4R-II 2.4G 4CH ACCST Telemetry Receiver, the most “advanced” receiver (telemetry, CPPM…)
- FrSky V8R7-II 2.4G 7CH Receiver, a good 8-channel receiver
- FrSky VD5M 2.4G 5CH Micro Receiver, the smallest receiver, 5 channels
Let’s start removing the original tx module from the back of the radio. With a Phillips screwdriver, open the module and desolder the antenna wire:
You can now pull out the plastic antenna after having unscrewed it and finally remove all the different components:
Before being able to install the new FrSky module, on some models of the Turnigy 9x radio – including my own – a small modification of the plastic case is needed. Open the radio and unscrew the PCB in the back, to be able to pull out the 5 pins that connect the radio to the receiver:
Now remove the plastic emboss around those pins:
After having closed again the radio, you can now install the FrSky module and screw its antenna:
No changes to the configuration of the radio are required, you can simply turn it on and bind the new receivers!
Ciao!
Hai per caso conservato qualche vecchio modulo RF 9X V2?
Se si sarei interessato ad acquistarne uno, da tenere come ricambio per la mia Turnigy. L’ho modificata a 16 ch con due moduli ma uno di questi comincia a scaldarsi un poco… 🙂
Grazie mille comunque,
Buona giornata!
Fabio
ciao Fabio, purtroppo no…
