A 1939 design with my modern updates . 110" wingspan . Electric motor with folding propeller . Three controls ; rudder, elevator and throttle . Mostly balsa with some plywood in high stress areas . Fiberglass and carbon fiber also added for strength in the boom area . Scratch built from plans . I am also in the process of designing my own 3.8 meter powered sailplane . The wing will be laser cut for accuracy and time saving . I have a friend in Washington state doing the Cad work . I've been at this hobby for 60 years so far . Keeps me broke but happy !
