That stuff is all so very awesome to me. I’ve owned model rockets but never launched them (boo massive urban centres), and I have nothing but respect for those that do. The law here about the really big model engines totally promotes that sort of dedication, too - if you want a license for the serious engines, you need to show a dedicated plan to a group of other rocketry fans and get their approval first.
It’s a club I’d love to be in but know I’d never muster the dedication needed to do so.
But this lego kit? This lego kit I can do.
