Hi BZR,

Here is what I have set up on my radio.

I did a mix with Throttle as Master, Elevator as Slave, link and trim both off, I assigned this to switch A in the down position. On the next page, I set the first rate at 0% the second rate at
-100%, then used the Offset moved the throttle down to as close as 25% as I could and pressed the dial.
What I end up with is regular throttle with switch A up, and with switch A down I get down Elevator which is porportional to my lowering throttle stick. I did not have a problem with this offsetting the center travel of my throttle servo at all.

I am taking a guess here that you are using a 9C but this mix should work with the 9Z also.

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.
