AeroTech 1.9 x 9 英吋無槽機身管 - 11909

The 0.04 inch wall thickness feels sturdy but still easy to cut with a hobby knife. It slides onto my motor mount without any sanding needed, which saved me time on this scratch build.

I was relieved this tube fit perfectly with my existing 1.9 inch components, and the 9 inch length gave me plenty of room to build a stable rocket. The inner diameter of exactly 1.8 inches made motor retention super easy.

The wall thickness is just right for my mid-power builds—sturdy but not too heavy. I used it to extend a payload section, and it glued up cleanly with no warping. Easily the best plain tube I've bought for the price.
