Eachine Fury Wing spar reinforcer

thingiverse

I've found that over time the foam hole for the spar on the Fury wing tends to warp into more of a cone shape with a worse and worse fit on the spar over time. Additionally, if you race this wing hard you can actually fold the wings by having the spar tear through the thin foam layer on the bottom of the wing cord. To fix this I designed inserts that should slide into the spar holes. The inserts act as a plastic sleeve to the carbon spar and provide much better support for it than just bare foam. Additionally they can be foam-safe CA glued into the original spar holes to provide even more security against the spar breaking through the bottom of the wing foam. You may find that the inside diameter needs to be sanded a bit to allow the spar to pass through. It's meant to be a tighter fit than the bare foam, but not so tight that it prevents the wings from popping off in the event of a crash. Make sure the lip around the hole is flush with the rest of the wing foam, otherwise it will prevent the magnets on the FPV pod from creating a tight seal with the wing magnets. The 50mm version is for people who are buying this wing brand new and intend to put this mod on it before any serious airtime has been put on the airframe. the 100mm version is for people that already are noticing issues with their spar tube diameter, or have had a wing fold.
