I fly with the 9c and there are alot of switches on this radio so I keep it simple and uniform to all my funfly planes.
first on all my planes funfly or not, duel rates are on the left top side in alphabetical order.
so the ailerons switch is the first switch and the elevator is the second switch. I don't need tripple rates. depending on the plane low is calm and high is to kick it up a knotch. with a speed plane high is to take off/land and low is for the speed part of the flight.
then I use flaperon/elevator mix with all my funfly planes. that goes on the right side of the radio on the long two position switch. I use the switch to turn it on or off only, the flaperons slave to my elevator controles. Some planes like it on all the time and others like it off all the time. when it's a plane that likes to have them off usually the only time I turn them on is in tight loops or tight spins..
I have played with spoileron mixing slaved to throttle (throttle below three clicks and spoilerons rise) but I don't fly enough that pushing the plane down on low throttle to get a faster landing time is that important. again though when I did try that I always have it mastered to an on/off switch this way If I don't like it I shut it off and don't have to land. then after the flight I remove it from programing.
I don't mix any other things to my funfly planes. I don't feel the need to at my level.
