Emma V. ★★★★★

The 9.75" length gave me just enough overlap to join my airframe sections with room to spare. Fit is dead-on at 3.9", no sanding or shimming needed. Cure time was worth it.

Riley ★★★★★

Waited the full four weeks for this to be made but it was worth it. The carbon weave is clean and the 9.75" length gave me plenty to work with for the coupler section. Slid right into my build with no sanding needed.

Evelyn ★★★★★

The fit on my 3.9" airframe is dead-on, no sanding needed, and the 9.75" length gave me plenty of overlap for the coupler joint. Carbon weave looks clean and the wall thickness feels solid.
