So, Guys if you have a 9x and you are tired of all limited functionalities and boring UI with very few options of tweaking stuff you are at the right place.
Note: you need to know how to solder as its not that easy as it looks, right soldering ion is needed also some programming knowledge if you go wrong somewhere.
If you are lazy and do not want to read the post skip to the video its easy to understand : youtube/bmsweb
Thing you need to have to perform this mod :
Turnigy 9x or Flysky 9x : Find here
Soldering ion with fine tip
laptop with drivers installed
eepeinstaller : Find here any similar program will work
Er9x firmware for your version of tx : Find here
Open tx firmware : Find here
Well next you need to prepare you soldering ion and open up your radio remember battery must be disconnected and radio module should be removed while performing the mod.
Next step is to prepare 8 wires for soldering to the processor chipset, and then the wires goes to usbasp adapter or you can get a connector similar to this:
Follow the video for more details… video .
Remember to check the pin connection and pin diagram every time you solder anything cause that may be pain if you go wrong you can permanently solder and keep the wires with the plug inside also make a slot so that you need not open the TX every time you want to program the tx .
After you are good to go further go and solder the wires to the board as follows:
Now that you have soldered all the pins properly time to connect the usbasp to laptop or pc and install the firmware first you need to download the drivers and make sure that the com-port is detected.
Next you need to open the software Eepeinstaller from there you need to make sure that the tx is selected and flash the er9x firmware you have downloaded earlier.
Thats it!! You have flashed the 9x with er9x and now you can connect the battery and switch the tx on so as to check it will beep if you have any switches on juss press okie to override them calibrate the tx sticks and configure the Tx as you want it to…
