Its where the fuel is some kind of plastic, and the oxidizer is most likely
Nos (the name one you use for cars, like need for speed underground 2) and
the whole thing is lit using some kind of ACPC composites and the gas is
released using some kind of pyrovalve. The advantages is that no licenses
are required because the fuel isnt considered "flammable" or "explosive"
A hybrid is a motor with one component solid and the other liquid. By
far the most common have solid fuel and liquid oxidizer. There are
"reverse" hybrids, with liquid fuel and solid oxidizer, but they are
Hybrids are gaining interest in the hobby because a motor can not only
be safe, it can be completely non-pyrotechnic until it's loaded with
oxidizer on the pad. Most hybrids can be shipped and stored with no
regulatory problems or hazmat restrictions because they aren't
hazardous. The oxidizer we use, nitrous oxide, is not classified as a
hazmat or flammable gas; it is handled with the safety rules that
apply to compressed gases like CO-2.
I have written an introductory survey of hobby hybrids here:
I hope you find it useful. I'll be glad to hear any questions!

Actually that's only one definition of a hybrid. A hybrid can also be
completely solid. In other words it has a solid oxidizer or oxygen generator
section and a solid fuel section. Another hybrid configuration uses a solid
oxidizer section and uses a liquid fuel as you pointed out. This again is
known as a reverse hybrid. CTI has been developing both of these types for
commercial and defense applications for a few years and has been granted
patents on the advanced packetized oxidizer technology or APOX for short.
Some of this work may spin off into HPR in the near future.
