Went back to read the complete article in issue 20. it's actually a pretty nice setup other then having the rods so close. I think 6 or 8 would have been much more manageable on each rack. Kinda neat that each scout(cub) has their own launch button. Tho we generally prefer to have a single LCO controlling the panel, it does seem to have enough built in safety to allow these den size launches. Pretty cool project.
I'm really looking more at the hydrogen rocket and launcher in the same issue as something to do for Demos. Now that looks like something that could be fun
