I have a limited amount of flights on the E-motion at this time. My original set-up was taken from one of my Integrals minus any mixes. It turned out to not need them. The first flight needed no thrust changes and only a minor trim change with elevator. Rolling manuevers are clean, up lines and down lines are straight with no pull out. Rudder is strong but is still easy to get along with for small corrections. The E-motion has a large presence in the air with a very consistant flight speed. I have found when compared to the Integral I have been flying also electric the E-motion allows you to slow down much more without showing any wing rock. I haven't found the E-motion be too sensitive to CG changes at this point. This plane actually gives you time to plan for the next manuever. Because this airplane is built for electric power only it should be pointed out under normal conditions batteries are coming out at temperatures of around 112 F. During the contest at Lake City temperatures were around 100 degrees. Even then battery temperatures were no more than 123 F. To me this is amazing when you look at the E-motion's air inlets and outlets. The duct work on this plane does work. This airplane is big inside. You will not have any problems working with it. I'm using a Plettenburg for power combined with TruRC packs and have no lack for vertical even after dialing back the high end of the throttle curve to 80 %. Even with the size of this plane there is no weight issue. Hope this answers some of the questions that are out there.
