Really more of a proof of concept for me, but here is the Maiden test flights of my T Tricopter. First lift is just the the KK controller only doing all the work, and the second segment is with the FY-20A added to the system. Not fully balanced out so not the best demo, but as I say a proof of concept for me anyway.
