hello. i have giles202, which I built from plans, don't remember which. and when I fly on it on high rates I mention strange thing. at the end of loop or turn on max control furfaces it drops one wing down. I have pic of airfoil here, maby it's unnormal, or maby my cg is out of zone, or 35 degree control movement is too big for giles202? plz need your advice. it weights 3.4kg dry weight and powered with magnum 91rfs
