أنبوب جسم غير مشقوق AeroTech 4.0 × 19 بوصة - 14019

The outer diameter of 3.98 inches fit perfectly into my 4-inch coupler without any sanding needed. The cardboard is thicker than some other body tubes I've used, so it feels solid for a high-power build.

The inner diameter of 3.9 inches made sliding this onto my motor mount a perfect snug fit—no sanding needed at all. Cut cleanly with a hobby knife and took primer great for painting.

The 3.98" outer diameter fits my fin can perfectly, and the 19-inch length gives me plenty of room for the payload bay I’m planning. Tube is stiff and true round, no warping along the whole length.
