A lot of amateurs can make APCP, but I would not call it an amateur
propellant. HTPB binders were pioneered by amateurs. The aerospace industry was
using CTPB binders in the 70's. Ray Goodson read about HTPB resins and
spread the word to Bill Wood, myself and others. I'm sure Ray had more
experience with HTPB than Thiokol with the release of their patent in 1978.

Once you get to the same level of complexity required to make APCP it's
wiser to go that route from an ISP standpoint.
I don't think a hybrid would qualify as a sugar rocket that's a hybrid
rocket, but that is just my opinion.
Don't get me wrong I like Sugar rockets for there usefulness and 50km
sounds about right for a decent sounding rocket.
Besides who says APCP is not an amateur propellant? I see plenty of
amateurs producing APCP propellant. We made our own. Anyways I've said
enough you guy's can decide what you want to do without my assistance.
Sugar rockets are for sure lots of fun. Enjoy!
