أنبوب الجسم غير المشقوق AeroTech 4.0 × 23 بوصة - 14033

The inside diameter is exactly 3.9 inches, so my altimeter bay slid in snug without any sanding. Cut it cleanly with a hobby knife and the tube kept its round shape through the whole build. This is the second one I've ordered and they're always consistent.

My Estes payload section wasn't fitting right, but this 4.0-inch tube’s inner diameter of 3.9 inches is perfect for my custom build. The 23-inch length gives me plenty of room for a dual-deployment setup. Such a clean, rigid tube.

The outer diameter is spot on at 3.98 inches, so it slid right into my fin jig without any sanding. Build quality feels solid for the length, and I've got no complaints about the fit on my current project.
