These are the instructions for the Compressed Air Rocket launcher v2.1
We are always working to improve things, so after shipping ≈250 of the CAR v2.0 kits and fulfilling all of Kickstarter our orders, it was time to get more serious and simplify the design for higher volume sales. I wanted something more portable and stable, so after going through about 20 different designs, this "X" style slide together wooden base was chosen. This new base design allowed for smaller packaging for lower cost shipping, easier angled launches with the U-bolt adjustment, storage for the launch tubes in the base, and grooves to wind up the orange tubing around the base.
Sold in 2015, replaced with v2.2 in 2016.
These are the instructions for the launcher that started our business, the Compressed Air Rocket launcher v2.0 that were first produced for our Kickstarter backers. The old project is still shown on Kickstarter here:
