Avery N. ★★★★★

Snug fit over the 24mm motor mount with almost no sanding needed, which saved me a ton of time on my scratch build. The plywood is thick enough that I didn't worry about it flexing under thrust.

Alexander ★★★★★

Snapped the 24mm ring over my motor mount tube and it seated flush with zero sanding needed. The laser cut is clean enough that I barely touched it before sliding it into the 3.00" airframe. Two spares in the pack means I'm set for the next build.

Andrew Z. ★★★★★

I was worried about getting a clean fit on my scratch build, but these centering rings slid over the 24mm motor mount tube perfectly. The laser cut edges are clean enough that I barely had to sand anything before epoxying them in.
