RC Airplane DC3 / C47 Prop Hub

thingiverse

Created a replacement prop hub for one of the gents in my RC club who has an Empire Air DC3 foam airplane. Don't recall who makes it, or if it's still made. He broke one of the prop hubs and couldn't find replacements. I printed them in PETG using supports and 0.1mm layer height. I'd stick with 100% infill, as they are kinda small and spin rather fast, so you want them to be solid. He's flown it quite a few times with these replacement hubs without any issue.
