I use that same radio. With the R700 reciever, it should be marked for all your different channels instead of numbered, Use Ail for one side & Aux1 for the other side (no y-harness). Then go into your EPAs until you find your aileron throws & set them where you want them on both low & high rates. Then in EPAs find your flaps & set the throws there too. Now you won't need a lot of throw on your flaperons, if you do it will send it right back up in the air. I think I had to do some reversing before I got it all to work right. I believe I may have had to switch the leads between the Ail ch & the Aux1 too because I got it wrong the first time. Then I used a couple of short servo extension wires to plug into the reciever with corresponding tape of yellow for one side & red for the other so I can leave those plugged into the reciever & just plug the servo leads into the matching color tape when I take the wing off & on. You can then assign what switch you want your flaps to be on. When all is said & done, if you have it all programmed correctly you should still have aileron control while the flaperons are down. By that I mean with the flaperons in the down position I can hit right aileron & my left side will stay down as my right side comes back up to neutral. They wont go one side up & the other side down like normal aileron function, just one side down & the other side back up to neutral, but this will give you enough aileron control during a landing approach to level out your wings if need be.

I hope I'm getting this all right for you because I just kind of stumbled thru it the other day with one of my new planes. I should have set it up per the step by step instructions in my manual but I thought I could feel my way thru it. Apparently I got it right because a friend & club Instructor checked it out & told me I have it all working correctly.

If you don't still have your JR6102 book let me know & I will scan & email that section to you.

I have no more than maybe 3/8 to a 1/2 inch of flap set in it right now. Charlie tells me it will be plenty & maybe even more than I need. The plan is to do a high altitude slow landing approach & hit the flaps to see what they will do with plenty of air under my plane in case it is too much. Then I will adjust them accordingly. I will have a flight report on them for you tomorrow. I have a few little things to finish today & will maiden the plane early tomorrow morning & let you know how it goes. I should be able to give you a proper throw measurement then too. Please let me know if you need me to scan that part of the manual for you. Good luck!!
