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 backlight makes such a big difference. makes the display crisp and clear. well worth the investment
Craig. Consider adding a backlight. That greatly increases visibility of the screen data.
All fixed, Turns out the programmer had two resistors that limited the current so it just reset each time it tried to flash. er9X is now living in my TX, I have spent a few hours playing now and I have set it up perfectly :). Can't wait to go fly my quad tomorrow! My Super sweet splash:
All running well:
This is Craig Burden, on my friend's account.
I have been trying to flash my 9X all day! Literally about 1hr after my last post until now I have been no stop trying to flash it! I am using the USBtinyISP AVR Programmer from Adafruit. I have resoldered my connections three times and checked that everything is connected from the connector to the pin on the MCU. I have tested the programmer on an Arduino Mega, works fine. I have tryed taking my ten pin to a six pin and using the programmers six pin port, doesn't work. I have tried leaving the port blank in AVRDude's settings. I have AVRDude v5.5. I have tried "-F" to ignore the initialization failure. I HAVE TRIED EVERYTHING!
I keep on getting the same error on AVRDude:
avrdude -C C:\WinAVR-20100110\bin\avrdude.conf -p m64 -P usb -c usbtiny -F -U flash:w:C:\Users\Cristopher\Desktop\er9x.hex:i
avrdude.exe: initialization failed, rc=-1
avrdude.exe: AVR device initialized and ready to accept instructions
avrdude.exe: Device signature = 0x000000
avrdude.exe: Yikes! Invalid device signature.
avrdude.exe: Expected signature for ATMEGA64 is 1E 96 02
avrdude.exe: NOTE: FLASH memory has been specified, an erase cycle will be performed
To disable this feature, specify the -D option.
avrdude.exe done. Thank you.
PLEASE HELP!!!!
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 :)
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.
Nice! are you using stock TX module?
My Splash I just made, going to wire up my TX and try flash it for the first time tomorrow! Excited :D
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
