https://www.apogeerockets.com/Rocket-Kits/Skill-Level-5-Model-Rocket-Kits/Terrier-Sandhawk - This video is the pre-build of the Terrier-Sandhawk model rocket from LOC Precision. Since the supplied kit doesn't come with instructions as to the process of converting it to a two-stage rocket, we as users have to design our own process to make it work. In this first video in the 10-part series, we'll talk about the problems that are associated with high-power two-stage model rockets, and particularly what is it about this kit that makes it more challenging. The process you'll see here is what engineers do - they try to think ahead about what challenges they'll have to face, and the options that are available to solve them.
