Somewhere online I found a site where they opened up one of the Spektrum modules and there was an added processor inside to do the PPM to "whatever" the RF portion required.
The only external components were for the 3.3 volt regulator circuit.

So try it first in PPM and DSM modes to see which, if any, works at all.

ya theres a microcontroller on another pcb board where it grabs power and the ppm i took the rf module off that board

Dear guys,
dont you have any picture of DM8 wiring in the removable module? If I understand, I need only to add the 3,3 stabiliser? Thanks a lot!! Ondrej

You don't need any compenent for a DM8. Simply wire the +, - and PPM.
You'll easily find Futaba and JR module pinouts on the web to see what to connect where.

Hello all together
Should we try to use the TX-Modul that "hammer22" on RCgroups is using to built his own.
http://www.rcgroups.com/forums/showthread.php?t=1669239
voila 12 Channels DSM2 and DSMX .
The Module hammer22 has made uses PPM and convert it to serial.
For 9x Users it would be better to use direkt serial.(binding, model match,DSM2/DSMX select via Software)
Eventually would erazz PM to hammer22 an talk a little bit about serial control of this tx Board, to get the best out of it
Cheers Werner

My thoughts - the main reason IMO for using DSM2 is for the BNF planes.
And none of them need more than 6 channels, so a DX4e module is the best solution in this case.

Electric helis are fine with 6 channels, and so are most aerobatic planes.

If you want better RF link than the stock FlySky, then FrSky is likely a better option. DSMx receivers are quite expensive.

If you really need 12 channels then you are possibly doing FPV? And in that case UHF is better I think.

Can anyone confirm the AMTX11 module will work on 8 channels with following pulses.cpp modification:

AFAIK the DX4/5/6 modules will not take anything beyond CH6.

Back when we were working on this I tried various things to get more than 6 channels, nothing ever worked.
