9C Programming
I have owned a Futaba 9C for a couple of years now, but only now am I trying seriously to use mixes.
Unfortunately, I find the manual quite confusing and I am just not getting the hang of using mixes.
I have a specific problem as follows: I want to use spoilers in an electric powered RES glider both as spoilers for landing and as a substitute for ailerons for lateral control. This is meant to work by assigning the channels as follows:-
Ch1 - Rudder
Ch2 - Elevator
Ch3 - Motor ESC
Ch4 - Left spoiler
Ch5 - Right spoiler
With the rudder stick neutral, spoilers are closed.
Left stick opens the left spoiler (R is closed) and Right stick opens the R spoiler (L is closed).
I got this to operate with a pmix and setting the servo throws(EPA) 0% and 100% appropriately.
However, I could not then come up with a mix to operate the spollers together using either Sw B or Vr-D.
On reading your FAQs, I notice frequent use of Offset mixes, but don't see what they do. Also, the assignment of Link is something which gives me trouble.
What non-expert users could use is, in my opinion, guidance on a few general principles and perhaps an example of the way which, say, flaperons could be implemented using mixes instead of the built-in functions.
I would be most grateful for your help on this one.

RE: 9C Programming
Hi Kevin, I tried to set mine up as closely to your set up as possible, although for anything over a 4 channel receiver, my channel assignments were different than what you have.
But the easiest way to set channels 4 and 5 to work together on a switch is to go into a Pmix, make Offset the master and channel 4 the slave, set thise to the switch or knob that you prefer and then set the rates at +100%. Do this again with channel 5 as the slave to the same switch. If this makes your spoilers work as opposite, you need to change the percentages to -100%.
An Offset mix is very useful when you are wanting to do something of this sort, or for use with gear doors, etc. When set, it will tell a servo to go to a predetermined position (the rate that you set) in its travel upon moving the designated swithc, and stay there until the switch is moved once again.
Link is just as its name applies, it links a mix to another specific servo used in a previous mix. Say you have set up a mix from Aileron to Elevator, and link is turned on, then the radio will mix from Aileron to Elevator and if there are other mixes from elevator to other channels, it will also obey those.
As for other general questions, we have tried to offer as much support as possible, with our online manuals, extensive FAQ's and email and phone support.

RE: 9C Programming
Thank you very much, Krysta.
I will try your set up ASAP. By the way, I am using the standard 7 channel Futaba Rx (...127DF?) so I can also use the auxiliary channels. Would this be preferable to Ch. 5?
I guess one thing still bothers me - if I create a third mix Ch. 4 with Ch. 5 and control with the rudder stick (Ch. 4 as Master and Ch. 5 as slave) to obtain the differential (pseudo ailerons) action, can this work all the time, i.e. can the spoilers be deployed simultaneously with Sw. B?
I am slowly learning!
