Besides for for the non commercial user, there is a whole host of CAA regs to abide by.
Which none of them will read. Recently in the US the FAA attempts to prosecute a similar UAS operator using their policy statements failed because the judge said they had no legal effect. There is a continuing legal battle in that area. See:
Trappy and the FAA fine for flying over the University of Virginia | Personal Drones
I can assure you that the commercial UAS manufacturers are more worried than you are about their market being killed by someone being silly with a 'toy' UAS. Just wait till after Christmas when the sky is filled with Christmas UAS.
