Are you part of the team?<p>I was looking for more technical info, like what "bi-propelant" means. It took me a while to find <a href="https://gruyerespaceprogram.ch/program/F-100.html" rel="nofollow">https://gruyerespaceprogram.ch/program/F-100.html</a> (linked in the main page, but I didn't see it.)<p>> <i>F-100 is our rocket hopper bi-propellant engine. This engine uses N2O and IPA for a maximal thrust of 1.2kN and a minimal thrust under 0.5kN.</i><p>IPA is isopropanol?
