I have that radio but i do not have the gyro. I have seen some videos of setting up various quad controllers. If its like any of the stuff i ave seen you will do your channel assignments in the controller software.
If you need mixing beyond what an airplane would need you may not be able to do it. I have found that the mix options in the mix menu don't work.
I was attempting to mix my duel rate switches to one switch and i could not get them to work. I recon that you will only need a few radio features like duel rates and expo, throttle cut and throttle curves finally maybe a fail safe.
With the props off hook up everything and connect to your pc and see what options you have and start tinkering.
Sorry for not being much help but that should get you started.
