oh i see ! thanks a lot for your support

ok i flashed it !
Hm....so for the telemetry mod i got to cut the traces on resistor 1 and 2 (i mean the resistors counting from the blue cable on your photo) right ?

ok thanks ! oh and something that i completely forgotten ! I soldered the wires on the motherboard....but i got a problem...in my AVR programmer there is a jumper...it has 3v and 5v witch one is the best for the turnigy Tx ? And also some thing that missing on the most tutorials.....do i have to con...

hmmm i see....ok thanks !

Oh something else about the backlight...do i have to do the mod with the transistor or i can directly change the brightness via the firmware ?

Oh nice ! thanks a lot for your reply !
So all i got to do is to flash it with custom firmware....but which one has the most features ?

Ok so finally i got my TH9x Tx i already installed the FrSky DHT module and i'm waiting for the resistors to complete the telemetry mod.
And now i will solder the programer to flash it !
But i got some questions.
Do i have to do the trainer mod or it's possible to fix it with software modding ?

So in my case i use the Option 2: inverting the signal using FUL-01

Oh i see ! and one more thing....do i need a TTL converter for this bluetooth module ? http://dx.com/p/wireless-bluetooth-rs23 ... -844080711

So it will work with the DHT, right ? yes Tx only i know

for telemetry on the android...if it's not possible then is it possible to solder it on the DHT module ? cause i found a tut about adding BT module on the DJT/DFT http://flitetest.com/articles/Adding_bl ... try_module but i don't know if i can do this on the DHT....

Guys is it possible to add a bluetooth module on the stock 9x board ?

hmmm i see....yes i want to blink only not to be much bright...ok instead of a 330Ω resistor i will put a little smaller....i think a 200Ω is what i need....we got 5 Volts and the SMD i got need 20mA....so with the 200Ω and 5 Volts i got 15 mA, it's ok i think...

Wow now i'm totally confused.... :/

hmmm i saw sparkfun's TTL converter and it had leds on the TX and Rx..... https://dlnmh9ip6v2uc.cloudfront.net/images/products/8/7/8/0/08780-03-L.jpg https://dlnmh9ip6v2uc.cloudfront.net/images/products/8/7/8/0/08780-01-L.jpg and it's schematic here: http://www.uchobby.com/wp-content/uploads/2007/06...

Hmmm is it possible to make a schemAtic please ??? ^^

I had an idea to add LEDs on FrSky's TTL converter....but i don't know if this will drop the voltage to muck and it wont's work at all....
Here is what i mean.....



Any idea ?

I think you don't need the ttl lite to upgrade the D8R II+

yes i'm thinking to solder 3 wires (required for upgrade) on the module and on the other side a mini usb and make a hole on the transmitter and glue it....so when i need to update it i will plug the FrSky USB Dongle onto this mini USB....

oh i see thanks a lot !!!
I had one idea....what about to have the TTL always on the module and be able to upgrade the module ?
Something like this...



I don't want to open the transmitter all the time....

The documents you need are here: http://www.frsky-rc.com/download.asp?id=22 Yeah i saw that earlier but it doesn't help to my question....;) The DHT has a male plug... but with a little rubber cover on to prevent short circuits when not used. Hmmm i see but then how the TTL converter fits on the DH...

Ok i order the FrSky DHT 8ch module and the FrSky USB Cable (http://www.hobbyking.com/hobbyking/stor ... duct=16665) but i noticed that both of them have female plugs.....ho can i upgrade the module ?

Oh i see ! I was thinking tha you get data via wifi on the phone....
Thanks for your reply !

Hi guys !
Is it possible to get FrSky telemetry on iPhone ? Spektrum support iphone monitoring....

Oh i see...i think i understood...well i'm new in this thing...hehe every minute i find something new :p

Xp's firmware is better ???

Also what's RSSI (PWM) and CPPM ????

Yeah i saw that earlier and i can say that i can't find any difference xD

Well like i say in the title what the difference between the D8R-II plus and the D8R-XP
