Please note that it comes with 8 wires total (1 red + 7 black), but you will need to soldera total of 9 wires on this 3 in 1 module. So you need to prepare 1 more black wire to connect the second GND of the module.
I share my soldering artwork if its can help : http://fr.tinypic.com/r/2h5tgtt/9
I still not received my second 2.4Ghz antenna when I did that mod so I didn't bring the antenna outside the transmitter body. Note it still does work fine for my indoor quads flight with the antenna lying in the devo body ;-)
