Hubsan X4 with DEVO 12S

Hello,
i'm a newbie with DEVO12S……
and i'm totally lost with the modifications to make on my DEVO 12S
I have got a Hubsan X4 and i would like to control it with my DEVO 12S
I know i need a A7105 module (i have it) to put into the radio
So have you got a photo or tutorial for how to connect the A7105 module into the DEVO 12S ?
After i know i need to make modifications in firmware of the DEVO 12S and install DeventionTX
But i don't understand how to make it, i'm afraid to make mistake, so witch modifications i must do in firmware of DEVO 12S ? How to install Devention TX ? have you got a step to step, tutorial or other ?
Sorry for my bad englishe, i'm french….
Thanks very much for your help

On your left, in a menu cryptically named "User Manuals" there are ... User Manuals, and among them - ModuleInstallation.pdf

Check it first, if you have further questions, don't hesitate to ask.

With firmware - you need to replace it with Deviation firmware, which is totally different from the original one. The process is also described in www.deviationtx.com/user-manual/Document...tion8UserManual.pdf/

And it´s all ?
No other modifications to make for hubsan x4 ?

What else did you expect? Solder a module, replace firmware, grab a model file for your model from this forum.

The firmware procedure is the same for devo 12S as for devo 8S ?

About this I am not totally sure. I recall vague mentions of "library", which is 12-specific. How about the document? Are there any words in it? It's combined Devo6/8/12 manual. There is a French version in the same place, by the way.

I'm afraid to make mistakes !
