What about small model planes? Are these also restricted?

Oddly enough, I can find no regulations specifically mentioning RC planes.
The obvious regs, such as for ultralight vehicles, specifically state that
they are applicable only to manned vehicles.

Perhaps you or others could search the regulations and come up with the
relevant cites and post them here - I had no luck finding anything covering
unmanned aerial vehicles:
