What other Homemade Solid Propellants exist besides rcandy? Is there
anything a bit more Powerful and easy to make? Ive tried looking
around, but Ive come up with nothing.

80% K perc / 20% fibreglass resin ?

Fiberglass resin, i.e. polyester resin, totally sucks as a binder because of
the high shrinkage and extreme brittleness. You can accomplish much the same
sans the severe shrinkage with epoxy binder.
