The rules sir, are an ass.
Please explain how the fact that their *might* be a commercial result to my flying an RC model should somehow make the risks associated with that flying so great as to require a full-sized pilot's license and a raft of other compliance hurdles to be negotiated -- while at the same time people with far less skill/experience are crashing their RC models in parks all over the country on a weekend?
Did you even read what I posted?
Unless your children are tresspassing and illegally standing in a privately owned grassy field miles from anywhere in the middle of the countryside (which is where I would be flying my 900g RC model), how would I be flying over them? Do your children regularly tresspass onto private property? You need to teach them about property rights.
They are far more likely to be hit by some novice RC flier trying to control their much bigger and more powerful RC helicopter or plane down at the local park.
And remember -- we're not talking about a "drone" here, we're talking about an RC plane that weighs 900g, is made of foam and is simply a vehicle for carrying a few bits of electronics into the air to collect some data. You do know the difference between a foam RC plane and a Predator don't you?
So yes, I guess (even if only because I read what others have written), I guess I *am* smarter than some -- well smarter than *you* anyway. :-)
