Flap to Elev mixing on T8FGsuper

My Feedback: (25)
I have separate aileron, elevator and flaps, right and left side. Because of this all of my first four pre-mixes are used. I was going to try PM5 when I saw about CMBFLP to ELEV on page 98 of manual. If this is the right thing to use, I can't get it to work.
I have my flaps on switch SG (up, half, and full down). No matter what I set in Rate 1 and 2, the elevator only moves when switch SG is in the full flap position, and then only the elevator plugged into ch 2 moves.
Can anyone help? I would like to program in a slight amount of down elevator at half flaps and a little more elevator at full flaps.
thanks, Steve

First off, what wing type have you selected? If your wing type is 2AIL+2FLP, you won't need so many pmixes. Also, select "Ailevator" as the tail type. This pre-programs dual ailerons, dual flaps, and dual elevators. Go into the Function section of the Linkage Menu and set the Camber function to the switch you want to operate the flaps from. Set the flaps to have "" as the control. You'll operate the flaps via Camber.
To get the flaps, ailerons, and elevators to all work together, you need to go into the Camber Mix. This sets everything up. Set the flaps to 100% in all sections. Don't bother about anything else, yet.
Go into the Dual Rate section and select the Camber Function. Now, go into the Model Menu and then the Dual Rate section. Selectc "CAMB" as the function to change. Move the switch to the full "flaps up" position. Set that endpoint to 0% Set the "NT" (neutral) position to 50% for now. This moves the flaps so that one switch position will have the flaps in the up, or stowed position, the middle position will be 1/2-flaps, and the other position will be full down. Use the linkage to set up the flaps stowed position. You'll then adjust the NT and full down points to get the flaps in their proper positions for those switch settings.
Now go into the Camber Mix and adjust the elevator movement for the flaps. Adjust the different rates as necessary to get the model to act as you desire. This will take several flights to get them set up properly.
If you want the ailerons to droop as you deploy flaps, adjust the aileron movement in the Camber Mix. If you want the flaps to act along with the elevators, use the "AIL->CMBFLP" function. This changes the wing so that you have full-span ailerons and flaps.
You don't need to use any special p-mixes, and the trims will work for all of the surfaces involved.

bax, thanks for the help. This 8FG just drives me crazy.
Right now PM 1 and 2 are Sw SG > Flap, to control 1/2 and full flaps. PM 3 is Elev > aux 2, to link right and left flap. PM 4 is Sw SE > Gear, and right now I can't remember why [
]. Before I get into your guidance should I make my current PM's 1, 2 & 3 INH?
Thanks, Steve
PS: this the 30cc H9 P-47 i'm setting up.

Bax, I think I am getting it all sorted out. Making progress anyway. When I made all those changes you suggested, it moved all my surfaces around to different channels, but I got that all sorted out.
Question: I need one open channel for my optical kill switch. My radio now says Ch 9 is CAMB on switch SG, but nothing is connected to Ch 9. Can I change the switch on this channel and use it for the optical kill?
Thanks again.
PS: no that didn't work. In order for the flap>elev mixing to work ch 9 needs to be on flap switch even though nothing is connected to ch 9. Don't know why.

"Nothing" is connected to channel 9 is not correct. You are using it as a "master" for the Camber function. You're just not using it to directly control a servo. Select any other unused channel. As long as your receiver has enough servo outputs, you'll be OK.

Bax,
OK, I got everything moving and in the right direction. Want to thank you for making me completely redo setup - just kidding of course
, really appreciate the help.
I do have a couple of questions just to clarify what I'm doing.
Question 1: I have numbers in CAMB MIX for both flap and elevator rate 1 and 2. Am I correct that this is where I set how far the flaps move at half and full; and where I set how much the elevator moves at half and full flaps? I have "0" set for aileron rates. Edit answer: Yes
Question 2: Is it correct that I am still going to set the elevator and aileron throws using normal end point and dual rate settings? Edit answer: Yes
thanks, Steve
PS: Got it all figured out. Bax, I really want to thank you for taking the time to help me with this. Somewhat complicated. If the manual was half as complete and understandable as you things would be a lot simpler. thanks, much

Actually, the transmitter isn't that difficult to use, you just need to think in terms of functions and not channels. Also, Futaba sometimes calls things a bit differently than we might. However, their addition of the Camber mix was a stroke of genius, since it makes many things so simple to set up.

I'm having problems I just can't figure out the 8fg!<div>I gave set up the radio in glider mode with 2aliron &</div><div>2 flap. I intend to mix the aliron to the flap say 30% </div><div>And want to use the throttle stick to use the flaps as an airbreak</div><div>With down elevator compensation to stop the glider</div><div>Gaining height when the breaks are down. I also want to add</div><div>Crow breaking but it seems to be called butterfly and my knowledge</div><div>Of the menu is so bad I literally want to throw it against the wall!</div><div>Can somone please help me... :-)</div>
