A LOT of model/high power rocketry is simply what we call 3FT flying, which stand for three fins and a tube, and that gets boring really fast. Another common and disparaging phrase is "whoosh - pop" as in the audio effect of repeatedly launching the aforementioned 3FT rockets. But do something interesting or unique and it is a neat hobby. As a big fan of HLG and free fllight in general, I can tell you that boost gliders are a real hoot, whether or not they are RC or free flight. They require the construction and trimming skills of hand launch gliders, the strength to withstand boost velocities, and to fly straight during boost. I really dig building and flying those. Really big, loud and fast motors (like above) are pretty *****in' too. The motor above is loud enough to deafen you up close. The photos above are taken from 1000' away which is much easier on the ears, but still pretty impressive.
