I have a Futaba 7C and am trying to program it for a Chipmunk with two aileron servos and a single flap servo. The ailerons are split so a single servo (for flaps) controls the inboard half and the the outboard are controled by the two aileron servos. I called Futaba and they set my programming for me but that was over a year ago and I don't know why I have the pmixes set they way they are. I will list them and maybe someone can expalin what is happeing, or supoosed to happen. Let me start with the servo radio connections. Channel1-4 are normal. Chan 5 has the Battery, Chan 6is the flap servo and chan 7 is left aileron servo. Here are the mixes:
Pmix 1- OFS- 6, Rate +77%,Master-OFS, Slave-6, Switch-G
Pmix2- Ofs-2,Rate -17%
Flaperon- on, Diff +5%, Ail-2-Channel 7
FlapTrim- on, Rate +-0%, +48%, OFS - Set
Flap-Elev- on, Rate -25%, OFS- Set

I have been pouring over the manual and picking up some data but can't tie it all together. If you have a thought please send to my email at [email protected] or maybe we can Skype? You can find me at tkennedy63 on skype. Thanks in advance. Hope someone out there can figure this out.
