Because the only limit should be Your imagination!
Turnigy 9X.


This site is outdated, please see [radioclone.org]


Hi everyone, my name is Rafal Tomczak and I live in Poland.

This site is meant to provide You with information on the system on which I'm currently working on. I need to thank Marek Spychalski, who is helping me in bringing the electronic part of that project to a new level.


If You wish contact me through sourceforge, please attach your email, or make sure your sourceforge address is correct! I often get rejects when trying to reply someone. If You don't get any response from me, then this is what might have happened. So Please contact me again, with reply address included.


Getting started

Project goal is to create replacement for software used in cheap RC TXs and create a powerful, limitless and fully configurable system.


As a system base I've chosen the Turnigy 9X (other brand names: FS-TH9X / Eurgle 9X / iMax 9X) because of its very low price, construction simplicity and clear design. This radio is based on ATmega64 chip from Atmel, which is well known and has free development tools.


DISCLAIMER: I HEREBY NOTE THAT I DO NOT TAKE ANY RESPONSIBILITY FOR ANY POSSIBLE DAMAGE AND/OR INJURY. ANY MODIFICATION OF EQUIPMENT AND/OR SOFTWARE IS STRICTLY AT YOUR OWN RISK.


You can read more details about this project here. Look in the current status section if You want to find out what I've done already and what is yet to be done.


Required equipment

To modify a transmitter, You will, of course, need one in the first place. The tX is available with differing names and brands:

  • Turnigy 9X
  • FS-TH9X
  • Eurgle 9X
  • iMax 9X

Even though the names are different, it is still the same hardware. So in this project You can use any of the above. More info in hardware section.


SD connector is now available - Many thanks to Marek who designed and manufactured it!

How to install SD module


How to install the software

I assume that You have completed the ISP installation and that You have the ISP programmer connected to Your PC. If not see here

You will need the following software:

  • avrdude (software for ISP programmer) or any other ISP software compatible with your ISP programmer hardware.
  • latest software version of "radioclone" from download section.


To create / compile / change software You will need

(assuming you are using Windows):

  • WinAVR
  • AVRstudio 4.0 from Atmel (it can be downloaded from atmel website)
  • svn client software (for example tortoiseSVN)
  • Sources for "radioclone" - can be downloaded from sourceforge by svn client.

If you are using other operating system You will have to find AVR GCC distribution for it. As far as I know it is available on linux too.


Other software for this Tx:

  • [th9x] by Thus (Thomas) & Josef
  • [er9x] by Erazz (a branch of th9x)
  • [gruvin9x] by Gruvin (a branch of er9x)
  • [msv19]
