The D-MOTOR in my Kitfox 2 is now functional. First engine start was Friday 18 Dec. 2020. Posted video on Youtube for all to see. Wish I could post it here. NOW FOR THE BAD NEWS! D-MOTOR is no longer exporting their engines. Every engine they build will be for the helicopters they manufacture. That's the latest info I have from D-MOTOR U.S.A.
