it should be the same as G3 or G3.5 here is what i did:
first since my rela flight didnt come with the cable and all od my e-mails have thus far went unanswered i made my own
instructions for it are below also
.
(copy and paste from my personal r/c forum that i started in september and am currently looking for new members)
ok for those that do not know and either have lost (or like me did not get one) thier interface cable and wish to use their own spektrum radio tx here is what you do:
first get yourself a 1/8" mono audio input plug and a piece of wire.
next solder the 1/8" mono audio jack onto one end just as if you would be using it for a mono audio device.
next take and jump pins 5 and 6 on the interlink controller with a piece of stiff wire
after that you will want to make your signal wire into a y (signal wire is the center pin on the 1/8" mono audio jack)
with that done you will insert the the 2 ends of the signal wire into the holes for pins 1 and 4
and teh ground wire (grnd wire on 1/8" mono audio jack) into pin hole 2.
see diagram below for pin layout on interlink controller:

the above shows the holes in the 6 pin port on the interlink they are numbers like this:
123
456
simple isnt it
next take and set up a profile in your TX and name it G?.?. realflight, or whatever just make sure you cna remember it is what is set when you want to use it for realflight.
once you have that done connect your interlink into a usb in your computer, and with your DX7 turned OFF plug the 1/8" mono audio plug into the dsc plug on teh back of your DX7, once this is done your controller will be recognized by the interlink as connected, start realflight, select interlink joystick, now there is only one thing left to do and that is the channel mapping.
here is what you need to do for the channel mapping in realflight:
after you have your tx connected, you select controller (interlink joystick)
then you select controller, then channel mapping.
here is exactly what you need to have from top to bottom
1 Channel 3 - throttle
2 Channel 1 - Roll
3 Channel 2 - pitch
4 Channel 4 - yaw
5 Channel 5 - Dual Rates
6 Channel 8 - 3 Position Switch
7 Channel 7 - smoke
8 Channel 6 - knob.
this is all you need with the exception of some of the above channel mapping having the revers box checked, this works on G3.5 through G5.5 as far as i know and is only for the spektrum radios however it may also work with jr if the pin out is the same on the 1/8" mono audio plug. enjoy
NOTE: this doesnt really work well for helis and i am currntly in the process of trying to figure it out (landing gear doesnt work on scale helis, and a few other issues)but it works just fine for teh planes i have tried.
