How do you program plain flaps? I want to use the switch 'C' for 2 position flaps-like up, 10 deg., 45 deg. I have one servo each side connected with a 'Y', and am plugged into ch 6. I can only get one movement. and it reverses between middle position and up and down. I did Pmix 1 and basically, at this point, I'm lost!

Just went through this for about three weeks!

I did not use a Y-cable, but I did use Switch C:

UP = flaps up
CNTR = flaps part way down
DOWN = flaps full down

I used the following PMIXs:

PMIX-1 mixed left flap ch7 to right flap ch8, 80%*

PMIX-2 OFS > ch7, -100%, Switch C UP, Link ON

PMIX-3 OFS > ch7, -50%, Switch C CNTR, Link ON

PMIX-4 OFS > ch7, +100%, Switch C DOWN, Link ON

PMIX-5 deactivated ch8 knob

* I had to reduce the % on the ch7 > ch8 mix to about 80% so that both servos had the same throw.

I also had to fiddle with NORM/REV on some channels to get it all right.



You could do the same thing with the Y-harness:

PMIX-1 OFS > ch6, -100%, Switch C UP

PMIX-2 OFS > ch6, -50%, Switch C CNTR

PMIX-3 OFS > ch6, +100%, Switch C DOWN

PMIX-4 deactivate ch6 knob

Good luck!

Thanks, Paul, let me give that a try. If the manual tell you how to do that, I can't find it. They spend so much time on mixing flaperons and elevators and all the exotic stuff, seem to miss the basics, IMHO!

HI wsmalley,


This should be easy to do with 2 Pmixes, the first one you will want to do is Offset as Master, channel 6 as slave, set this to the center position of your 3 position switch and make the rate 10%. Next do a 2nd Pmix again with Offset as Master, channel 6 as slave, set this to the down position of the same switch, and make the rate 40%.

At top position on your 3 position switch, you will have just normal flaps on your channel 6 knob, but with the switch in the center position, the flaps will drop 10% and in the down position, they will both drop 45%.

I hope you find this information helpful. You can also reach our Futaba support technical team at 217-398-8970, or via fax at 217-398-7721.

Using the two Pmixes did the job. I didn't realize that each Pmix corresponds to a switch position. I set Pmix 1 on the center position of switch C with about 15%, and Pmix 2 for the down position with about 90%. The flaps are, of course 'up' in the switch C up position. Thanks, Bill S.
