I need help with this mix please

[DenverDrones]

I am new to Open TX although I have been using computer radios for many years.
All I am trying to do is to mix "to" a channel that I need to move in the same direction regardless of the direction of the "from" channel. I created a CAR mix for my quad rotor and I want to mix in "forward" elevator for both left and right turns.
Can someone walk me through the right way of doing this?
Thanks,
Jerry, DenverDrones

In the Mix edit screen under 'Curve' set it to Func, then use|x|
You will want to use 10 to 20% Weight probably and RUD as the source as a second mix under ELV
.

Thanks so much. Thats exactly what I needed. I looked at the function list previously but was looking for something like ABS().
Thanks again,
JP

The two vertical bars are a symbol for absolute value, so you were on the right track.
