I know I promised an update last week but I ran into an unexpected opportunity to test out the GPS system and I've been busy working the analysis on that. So in return for no post last week there will be a more interesting post this week!

I'm back! Sorry to my readers (both of you) that I haven't posted in 3 months. Schoolwork got to be pretty intense and my dorm room was not really the best workshop. I'm now at home in NJ for a couple weeks before my summer internship starts and have oodles of free time to work on Project HAL!

I realized, after making that "thing" out of a construction tube and some balsa/plywood (see this post) that I had to rethink my design entirely. I'd also read that even though anybody can fly G class motors without a license, flying four of them at a time wasn't exactly a shortcut to more power with less paperwork.

So I went back to the drawing board and took a look at what a system with only one rocket motor would look like. Details after the break.
