Customer Reviews (4.8 / 5 · 5 reviews)

Jacob P. ★★★★★

The fit on my 3.9" airframe is absolutely perfect—no sanding or forcing needed. The 11.75" length gives plenty of room for staging, and the carbon finish looks sharp once installed.

Ellie ★★★★★

Waited through the 2-4 week lead time but it was worth it—the fit on my 3.9" airframe is snug and perfectly aligned. Surface finish is smooth enough that I didn't need to sand before gluing.

Ryan S. ★★★★★

The 11.75-inch length was perfect for bridging two sections of my airframe, and the fit over the 3.9" tubing was snug without needing sanding. Really pleased with how clean the joint looks now.
