Futaba 7C Programming Problem
 

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.

When you operate the transmitter, how does the model respond?

After much trial and error, I have figured it out. I had to undrestand the logic of the OFST command and its relation to the other surface control functions and how to use it. Once I realized it was used to tie several surface control functions together,It all be came clear. Now I'm the "expert" in programing at the feild as no one there ever went past a basic mix function.
