ok here is the story. I seen in a post that someone had mentioned page 34 -36 in the manual I looked and this tell you about the triple rates and expo to go along with it setup on the three way switch. your Ailerons will not need Flaperons nor will they be affected because they are both operation on channel 1. Now you can go in the Parameters setting and make channel 5 operate by the three way switch , but this will not operate properly because the middle position gives you nuteral flaps, the up positon gives you spoilers and the down gives you flaps. you can adjust the up and down rate but you can't reversoe it. So what you need to do is set up two p mixes. you have to go to the Perameters settings and null out channel five so no control or switch operates the channel. then what you have to do is setup the plane with the flaps neutral with the three position Up or down depending on your pereferance. what I did was made a programable mix and set it to turn on with the switch in the middle position and set the rate for the flaps to be half ( adjust rates to how much flap deployment you want ). Then I used a second programable mix to turn on in the up position on the three way switch and set the rates to full ( again set the deployment as needed) So your answer Yes It is easy to do with the single servo setup. now if you had the flaps on two channels you would run out of P mixes before you could have both flaps work in both the deployed switch postions as you only have three mixes and would need four. The radio is nice because you can asign any switch to do whatever you want. but I find one thing that I don't care fur. You cannont reasign the airbrake function which is default to the 3 position switch in the up position. I don't need airbrakes most of the time I guess I can sacrifice the airbrake for triple rates. I hope this helps.
