Free-flight is not a legal definition, more a philosophy. At its heart is the idea of flying purely for fun, usually locally, rather than with the object of going from A to B. True, some free-flight pilots have achieved astonishingly long record flights, but these are exceptional individuals; most free-flyers just want to turn up, take-off, play at being a bird, land, pack up and go home, feeling a warm glow of satisfaction at having seen our wonderful world from a position previously reserved for a priviledged.
