Yes it looks like you can change the direction of your slave channel easily. First, get into the PMIX screen. Push the SELECT key until you get to the % sign to flash. Now if I remember this correctly from the old 8U (the 6Ex looks similar) you can set the direction and amount by moving the rudder stick one way then the other. In other words, to set your left rudder - elevator mix, move the rudder stick to the left and adjust the travel and direction. To set the direction, you should see a "+" or "-" sign next to the percentage number. That indicates direction. If you start at +100 and keep decreasing the value it will go; +100 +99 ... 0 -1 -2... -100. Now move the rudder stick to the right and set your right rudder - elevator mix. I think this will fix you up. Unfortunately it looks like the 6Ex only has one programmable mix. A good Pattern airplane needs very little mixing if you know how to trim it out correctly. Sometimes though, you will end up with a few mixes. The more expensive radios are more flexible in this regard but for now you should be able to make do with the 6Ex. Hey- this didn't cost anything. Let me know if it works. It's always easy to throw money at a problem but sometimes your only option is to be resourceful.

Unfortunately the 6EX does not give you the ability to move the stick to the left and choose the value, then to the right and choose the value; it is one set value for one servo being completely slaved to another. EPA's and such you are able to do this, but not with the (2) P-mixes.
I feel like this is a big disadvantage, for things like doing knife edges or moves with a lot of rudder, but more importantly for correcting my line with rudder input. It would be advantageous to be able to rudder right or left without nosing down (i.e. having the computer do it for you so you can concentrate on other things).
Sounds like I need to do my research, and choose a good radio wisely, instead of rushing into something that will fix this one problem, as something else may pop up.
I'm strongly considering competing in the competition next weekend, even though I'm so new and probably won't be competitive. But hey, you never know!
Thanks guys.
