dougji I hate to burst your guys bubble, but this is illegal. You're not allowed any "sudden stop" launching mechanisms.
frc1726 (2 days ago) Could you please cite a rule, Q&A response, or team update paragraph that says that? We haven't seen any such thing, and would like to know if you are correct.

What is the definition of a "sudden stop" launching mechanism?

Frank
Not only does the comment on youtube represent an incomplete understanding of the very clever system that 1726 has devised, but also an incomplete understanding of the Q&A. It has been specifically answered that building up pressure in a pneumatic cylinder, then releasing it is perfectly legal given that certain other conditions are met.

There is an excellent discussion of this topic here http://www.chiefdelphi.com/forums/sh...threadid=62836 with links to relevant Q&A answers/clarifications.

In short... launch away my friends... just not in the pits and not using any system of compression other than the compressor, or any pressures exceeding 60 psi on the working side of the system.
