Jacob ★★★★★

The wall thickness on this coupler feels reassuringly solid, not flimsy like some others I’ve handled. It’s exactly 4 inches long, so my staging section came out perfectly aligned without any extra trimming.

Henry ★★★★★

Slid right onto my 1.805-inch tube with a snug, satisfying fit—no sanding needed. The 4-inch length gives plenty of surface for a solid glue joint, and this coupler feels sturdy enough for multiple flights.

Eli ★★★★★

The wall thickness is spot on at 0.08 inches, so it feels sturdy without adding much weight to the airframe. Slid right over my tubes and the 4-inch length gives plenty of gluing surface for a solid joint.
