Drilled 1x1 pinned to end of rotating tubes bolt to fit airframe or wing using "room door hinges as flex connections( sometimes welding brackets that are then centered to parts with 3/8ths bolts drilled into wingtips serve as mounts. fabric is glued over holes & paint hides smallpuncture "wounds". 5/8bolts extend thru 2" spaced hols to adjust height of telescoped tubes. band saw, miller tig & lathe, 2 day project.
