Miles Y. ★★★★★

Swapped these onto my Big Nuke 3E after cracking a stock fin, and the 3/8 inch thickness feels way more solid on landing. They fit the 75mm tube slots without any sanding, which I appreciated. Three fins, no wobble on the way up.

Nicholas ★★★★★

These 3/8 inch fins are seriously thick and stiff, way beefier than the stock ones that came with my kit. Installed them on my 75mm build and they held up perfectly through a rough landing. Exactly the upgrade I was looking for.

Lily ★★★★☆

These 3/8 inch fins are noticeably beefier than the stock ones, and the three-pack fit my 75mm motor tube without any sanding. Only gripe is the leading edges needed a bit of cleanup, but for a replacement set they're solid.
