I did a search, but couldn't find exactly what I was looking for.

I'm getting my first ever plane that has elevons and I was wondering how hard the programming is for it. I looked through my manual, and it seems pretty simple. I just have no idea what values I need to use and what exactly they mean. Is there a resource (other than trial and error) that explains this?

I'm guessing that the percentages for aileron and elevator control how far the control surface moves as compared to each other (or each other's inputs). I have no idea what "differential" is referring to.
Any help would be appreciated...
