Trying to setup a three position flap / elevator mix to mix a certain percentage of up elevator per switch (flap) position. IE: up = no mix center=10% elevator down=15% elevator.
Nothing I do seems to get the center switch position mix to work? I have tried it using the center/down switch position and also tried using 2 seperate mixes but nothing seems to add the mix with the switch in the center position (even though the mix says it's on?)
Any help would be appreciated

Todd, one thing you can do is set up a mix where the knobs are the master and the elevator is slave. Set up one mix with VRA as master and elevator as slave with switch C in the center position, and VRB as master with elevator as slave with switch C in the down position. This way you can adjust the amount of mixing in flight. You can also use an offset mix for the elevator.

Ryan,
I thought about that but.... Since this is on a tubine jet, I dont want to have the ability to alter the mix once I find the correct % of elevator / flap mix. My mix works fine on full flap but I cant seem to activate the mix with partial (switch center) flap? Even if I program a second mix to function at switch center is does not apply the mix?

I believe I have figured out a way to solve your problem.

I used 3 programmable mixers.
The first one is what makes the elevator deflect at down switch.
The second one is what makes the elevator deflect at the middle position.
The third one makes the flaps deflect at the middle posision.


I used mix 1. It should look as follows.
Mix: active
mas: flap
slv: elev
link: off
sw: c or whatever switch you want to use
posi: down
You then go to the first screen of the mix and put in whatever percentage of elevator you want.

Open mix 2. It should look like this
mix: active
mas: flap
slv: elev
link: off
sw c or the same one you used on number 1
posi: center
Then go to the first screen of the mix and input your elevator percentage there.

Open mix 3. It should look like this.
mix: active
mas: ofst
slv: flap
link: on
sw: c or whatever you used on number 1 and 2
posi: center.
Then go to the first screen of the mix and imput the percentage that you want of flap travel in the middle position.

If you have dual elevator servos you will need to have link on on the first two mixes.


That should accomplish what you are trying to do.

Thanks Ryan,

I'll give this a try although I am not sure I like the fact that I have to use three mixes to accomplish what appears to be a simple task? Wonder if this is a programming glitch within the radio software?

Todd

I have fooled with this a little more. You can use just 1 point mix if you have one of them open.


First you need to assign the flap channel to three position switch that you want to use.
Then open programmable mix six or seven
It should look like this.
Mix: on
Mas: flap
Slv: elev
Link: on if you have dual elevator servos mixed in the radio
sw: whatever 3 position switch you want to use
posi: null
Go to the first screen and set the points to the percent of elevator that you want in each position.

This will only use one mix.

Muchos Gracias!!! I'll give it a try tonight


Thanks!
Todd
