Actually Bront. I fly at a samaa registered flying club and often we have low flying full size aircraft flying over our club. Even though we are on your dont fly low notams. Yes the rule is give way to a full size aircraft, but often when you are flying you can't hear it. It is normally a non flying member that runs out and tells us to hit the deck. When you are flying your rc plane in a gaggle of rc planes your situational awareness is not looking for anything coming outside of the prescribed circuit. Club rules follow the circuit, especially newbies can't take their eyes of their plane or they lose it and crash. Full size planes and helis sneak up fast because you are fast to us standing on the ground and concentrating on a moving speck. You chaps in full size need to realise that we also have a right to the sky in our designated areas and respect that.
Times are changing and drones are here to stay. It's good advice that beaches will have drones fly low at your peril.
