Agreed, don't think it's just a FPV thing. Any model aviation craft could cause a negative reaction from the powers that be. A relative of some one "powerful" gets their finger bit by a prop and it will be mandated that props be made of child safe foam. Pessimist? Maybe. Tell me this scenario has never happened. I truly hope we are all able to continue enjoying this amazing hobby without being handcuffed with regulation. Wait and see. I still like the idea of a cert. on a post it note.
