Ava F. ★★★★★

Wasn't sure a quarter-inch thick fin would make much difference until I swapped these onto my Goblin. The material feels genuinely sturdy compared to the stock set, and the cut edges lined up nicely on the body tube.

Jacob ★★★★★

The 1/4-inch thickness feels way more solid than the stock fins, and after a dozen flights there's zero flex or chipping. Four fins per set also means I've got spares for my next build.

Ella E. ★★★★★

Swapped these onto my Goblin after cracking a fin on a hard landing, and the difference is obvious the second you hold one. The quarter-inch stock is beefy and the edges came clean, so they sanded up nicely before paint. Four fins in the pack also means I've got spares for the next mishap.
