Lucy W. ★★★★★

Broke my old fin can last weekend, so I picked this up for the pre-slotted airframe—cut assembly time in half compared to scratch-building. The through-the-wall fin construction feels rock solid on the bench.

Julian ★★★★★

The 1/4" LOC-N fins locked into place perfectly, making alignment a breeze even for a first-time advanced build. Through-the-wall construction on the 54mm mount feels incredibly solid, and the pre-slotted airframe saved me hours of measuring.

Samuel L. ★★★★★

The through-the-wall fin construction on this kit is rock solid, way sturdier than the surface-mounted fins I've dealt with before. Dropped in a 54mm motor and it held together perfectly through the whole flight. The pre-slotted airframe saved me a ton of build time too.
