Oké i Will try to explain it,
Make sure your quad/hexacopter works with the settings you now have!!!
Toen go to menu on your tx 
> mixing
>change AIL>RUD in to MIX1
>set ?>? In to AX1>AX1 
>set Rate: -50%
                     0%
   Offset:       0%
   Trim:     Inh
    Sw :      Ele D/R.  ( this is the switch name look at the switches on your tx and you Will see they match)
> now when your flick switch (set the 3way switch in gpsatt)Ele D/R you see that the slider move to say 62,5%(failsafe)
> go back to the home screen on your tx
(Check the switch position before power on the quad otherwise it could start to fly because hè is in failsafe !!!)
> now hook up the quad to your pc and check if everything moves good!
