Nicholas M. ★★★★★

Slid this into my 4 inch airframe and the fit was spot on, no sanding needed. The 3.886 outer diameter is consistent along the whole 6 inches, which matters when you're joining two tubes. Solid coupler for the price.

Zoe ★★★★★

The fit on this coupler is spot on for a 4-inch airframe, slides in snug without any slop once it's epoxied. Six inches gives plenty of overlap for a solid joint between body tubes. Way stiffer than the thin-walled stuff I've tried before.

Alexander A. ★★★★★

Bought this as a spare for my 4-inch build and it fit like the original. The 3.886 inch outer diameter slides perfectly into the airframe with no sanding needed, which is rare for couplers. Six inches gives just enough overlap for a solid splice.
