Tubo de cuerpo BT-20

From 4 tubes I was able to make 8 rocket bodies. That comes out to just a little over a dollar for each. With the free 3D nose cones and fins this makes for very inexpensive rockets.

Besides making some really cool rockets with BT-20 tubes, I make many standard engine mounts with these.

I have used Estes rockets for over 40 years. It started as a hobby when I was in grade school. It continued as I raised my own kids and now it will a hobbie I'll share with my grand kids. I do not have a large area to launch here in the New England region so I fly smaller models. I like to build my own designs and the parts that I get from Estes has always been perfect for my needs. Plus they are biodegradable so when I hang one in a tree to dry for a few months. I at least get the plastic parts back to reuse and send up again. Thank you for years of enjoyment.
