Starting with a solid motor (eg a commercial one) is IMHO not wrong. So
you get your experience with the airframe, avionics, telemetry, recovery
etc before you maybe switch to liquids. The chance is great that you
will never fly something if you start with the development of a liquid
engine first... for student projects it's important that you see results
soon to keep them motivated.

Me personally, I wish to see more Liquids doing this than Solids.
Solids tend to be in the Disposable Category, while Liquid tend to be
in the More Fun Category. But Categories tend to change from time to

The rocket was just a single stage solid with apparently lots of
attention paid to weight reduction. In the landed photo the
parachute looks small, but it's probably just a really light airframe.
