PK-72 Expediter Fin Set

The cut edges are clean and uniform, so they took glue without any fuss. I swapped these onto my Expediter build and the 54mm mount alignment was spot-on, saving me from any sanding headaches.

These fins fit perfectly onto the 54mm motor mount tube with zero sanding required on the root edge. The 1/8" plywood feels sturdy enough to handle high-power launches without any flex.

Cutting these fins to the correct bevel was straightforward, and they fit perfectly into the motor mount slots with minimal sanding. The 1/8-inch plywood feels sturdy enough to handle high-power flights without flexing.
