Correct. The points puncture the cartridge to let all of the gas out within 1.5 seconds.The cartridges are then discarded after the race. I also experimented with a refillable design using a plastic coke bottle, a quick release valve, and air pump to pressurize the bottle. . However, the resulting car was heavier and less powerful.
im curious... how do the co2 cartridges work? do those little points on the t-bar puncture the cartridge, and then all the air is let out? and if thats the case, then i'm guessing you can only use the cartridge once.
The big spring is connected to the T-bar with picture wire. The wire is tied to the loop in the spring, and threaded through a hole drilled in the bar. If you look at 1:23, you can kind of see how it's attached to the bar.

Thanks for the comments, everyone. Sorry, but there are no blueprints, just a bunch of tinkering. The best part IMHO starts at 3:15.
