For around ten years, the model helicopter fraternity have been flying and developing UAV's..but still the regulators are caught with their pants around their ankles.

Flexwing Microlights....ditto
Paragliders.....ditto
Powered Parachutes....ditto
Wait for the dead hand of authority try to stifle the latest innovation they don't understand.
