Fun stuff. There is an apocryphal story of an event at the annual Blackrock Amateur Rocketry fly off where the Bureau of Alcohol, Tobacco, and Firearms either confiscated (one version) or denied use of (another variation) a rocket that had been steerable fins and was designed to use orientation with the Sun as a means to keep it going straight up. The story goes that once a rocket can track a heat source and fly based on that track it becomes a "munition" and is no longer just a rocket.
That said, the information that you can make sophisticated weapons with off the shelf parts is not new nor necessarily rare. Everything from guns to armored machine gun platforms, drone bombers, to drone like cruise missiles seem to have not only been built but fielded in recent battles. It's hard to imagine that anyone can keep this sort of information "secret" by hitting individual web sites with cease and desist orders.
