Mike,
I have been using a Cortex in my Eurosport for about a year. I have full time canards working in pitch. Canard movement is per Euro manual. The cortex moves both the elevons and canards however the canards move very little from Cortex inputs.
I started with 20% gain and now fly at 40% all the time. It stops the wing rock except in the most gusty winds. It makes crosswind and gusty wind landings much easier.
Recently we had a local fly-in and the winds were very bad. Almost no one was flying. I put in 7 flights and folks were amazed. I'm not that good of a pilot so my answer to the questions about "how do you do that"…one word, Cortex!
Just put it in and program it and you will love it.
Gary
