There is plenty of info on modding the 9x Radio to make it better, I dont intend to tell people how to do it, only how easy it is to make the changes and show some photo's of the things i have added/changed.

The easiest addon was the balancing thing for the neck strap, makes it nice and level, and so much easier to fly because you are moving the sticks instead of holding the remote!

The kick stand is great when at home programming or playing on the sim, saves the cables getting bent etc. It clamps onto the handle on the back, and doesnt get in the way at all (even when removing the screws to get inside)

The next picture was the first mod I made, the 6 Position switch. Not really needed and I wish I hadn't done it now, I would use the 3 pos switch and the 2 pos switch mix thing thats descibed very well in the forums. Having said that, it is an easy mod and works well, I cheated a bit and used 5x 1K resistors and just use a curve to get the right points in MP

With the original RX I had a few problems, very intermittant, and only when banking left... spot the tiny ball of solder that shorts 2 pins on the IC in the RX module, it actually rolls back and forward under there. It very briefly connects channel 3 and 4 which I think must screw up the APM and cause a sudden crash! Removing the ball fixed the problem

The standard transmitter and receiver are a bit of a let down, and I want the best of the best! So the FrSKY DJT combo was ordered along with the FrSKYLite thingy bob for RS232 voltage level shifting. I added the FrSKYLite inside the TX module and used 2 spare pins in the rear connector so there is no extra hloes needed in the case. also used the 5V and ground pins from the outside connector. There is also a 4K7 resistor on one line (under the heat shrink) I dont know what its for but it was in a circuit diagram I followed.

The standard battery pack is a waste of time and i would bin it straight away. there are drop in batteries available that do the job nicely and are rechargeable, all you need to do is change the plug.



Inside the main unit there are a few changes required, the hardest one is removing 2 tiny resistors and connecting 2 lines to different pins on the microprocessor, the pins are super tiny and very fragile, but once its done its done. Adding the Smartie Parts board is easy, and even though I have the V1 board in the transmitter which has an incorrectly connected pad, its still an easy mod (just remove one pogo stick and add a wire connected to a resistor). This board is also where the MISO/MOSI lines from the FrSKY connect to. Easy!

Getting the signal is fairly straight forward, just cut a couple of traces on the back board (that ground the unused pins, there are traces on both sides incase you are doing the same) and we are in business.

The Smartie Parts board comes with a really cool blue backlight that makes reading the display really crisp and clear. And as the instuctions remind you, change the stupid + and - buttons around while your slipping it behind the display. Splash screens make this the best thing on the market, check out my super cool Octaquad splash!

The best bit of all this is the massive upgrade in the software, thanks to Thus and Erazz. The feature list is huge and as I just found out allows 16 channels to be transmitted! just plug another TX module into the trainer port.  Also there is a way to program the remote on the computer and set curves, mixers etc and even simulate the outputs on the screen. Once your happy then flash it to the remote.

Woo good work ! I don't think it is possible to do all this work with the 9x ! I will certainly do the same on mine now :)

I did a few mods to my new 9x last week and thought it would be a great idea to gather all available mods in wiki, categorized and well described. Any thoughts about it? (my 9x now - "white" backlight, flashed with Er9x)

@Chris Huitema

That looks fantastic, what firmware is that you have flashed?

Comment by Chris Huitema on June 1, 2012 at 5:11pm

Its r762 er9x-frsky-noht

here is the splash screen I made up for my yet to be built Octaquad, just waiting for 4 more ESC's and its ready to go!, might need to add a little weight to it initially, 1.5kg with 8x 880kv motors! including 5500mAh 3s Lipo. should really work on getting the camera gimbal and zoom lens going properly.

That white backlight looks sweet too Marooned, is it a HK one or the smartie parts one?

I would have gone the HK one and put in an external programmer but I just happen to be a Smart Roadster driver and had to have the Smartie parts board in there just coz its Smart haha

My Splash I just made, going to wire up my TX and try flash it for the first time tomorrow! Excited :D

Comment by Chris Huitema on June 1, 2012 at 5:56pm

Nice! are you using stock TX module?

Comment by Marooned on June 2, 2012 at 2:14am

Chris, it's from some local seller (Poland) but for sure he is ordering it from somewhere and has all 3 colors available (white, blue, green). I connected it using HK photos, looks the same. And I'm very happy for the white which became greenish because of LCD. Really clear and readable.

Comment by Craig Burden on June 2, 2012 at 2:20am

Yes at the moment it is the stock Turnigy 9X. I'm going to go in a few minutes to hopefully buy the ribbon cable! I will update you guys once I have tried :)
