Build Your Own Thrust Vectored Rockets for Vertical Landings Like SpaceX
Like SpaceX?<p>"If you love rockets, you can’t help but notice that real space launch vehicles lift off the pad slowly, but model rockets zip up like darts."<p>That reminds me of a common issue with modeling: when you divide sizes by N, you divide surfaces/light-reflexion/air-resistance/lift by NxN and volumes/weights by NxNxN.<p>A 1/10th model is 1/1000th of the original weight with identical materials. All the dynamics are different and easier at smaller scales. This makes the real thing an expert work while modeling is reachable by hobbyists - very good ones in this case.
