If I do a channel mix, then it will have adverse side effects when I do stall turns, and even giving it rudder on landing (we sometimes have a nasty crosswind).

I have a 25e Hyperion Yak 55 that flies awesome. You roll it on edge, give it rudder and it just has a very slight pitch coupling.

1) By definition (stall) ailerons will do nothing.
When landing crosswind you are 'on' all controls all the time.
2) Remember that ship fondly as there aren't too many that will fit that description.
Simply true.
Some use a switch for mixes some do not.
"IF" the rudder is causing a proverse roll coupling (or adverse) then it will do it all the time not simply in knife edge. Knife edge may be the most pronounced visually but the condition is occurring every time you use rudder. Speed will make it more noticeable as will time 'on' the rudder.
It simply isn't possible to trim an airplane to be dead neutral in all conditions all the time.
Wind direction and velocity will change that.
I usually choose to fly it through all but the most severe couplings. That way you are never too surprised by wind changes.
The full scale guys trim it "about right" then compensate.
Simply a learning process and after awhile you aren't even aware that you are compensating at all.
