I started my Kitfox S7 STi build November 2018 and flew it November 2020. The guys at Kitfox have been extremely helpful along the way answering questions with their heavy work load. The plane is powered by a Rotax 912iS, Airmaster C/S prop. Avionics include Garmin G3X touch, with autopilot. I now have over a hundred hour and can’t be any happier.
