I maidened mine last week, ended up with 8% elevator and 14% aileron to mix out the coupling. Controls remained responsive and even throughout the rollers and KE flight with these mixes. Flat turns were flat and easy to maintain.

I thought I was having thrust issues with mine (Saito 1.25 on the front of it), but it started lurching the opposite way(left) on some of my uplines. I dialed in some expo on my rudder to tame it down around center a little, and it is easy to keep it pointed up now. So much motor for it, if your not pointed perfectly straight up it wants to go off to a side. I don't know that i would mix rudder to throttle, because the thrust issues will change depending on which direction you are pointing and how hard you blip the throttle.

Hope this helps,
