5.5" Goblin Fin Set

The 1/4" thickness gives these fins a really solid, stiff feel without adding much weight to the tail end. Tabs lined up cleanly with my 54mm motor tube on the first dry fit, which saved me a lot of sanding.

These fins fit the 54mm motor tube perfectly and the tabs made alignment way easier than I expected. At a quarter inch thick they feel rock solid, no flex at all. Four fins in the set was exactly what I needed for the build.

I was worried about sanding the root edges down on these but the 1/4" thickness kept them sturdy the whole way. The tabs dropping to a 54mm motor tube made the dry fit a breeze on my build.
