I would say the easiest way is for an HOA board to vote "No"...

FWIW... I wonder if the influence of the heli pilot getting killed in New York plays into this. It is recent enough to spark hesitation in anyones mind that doesn't understand.

With that said, I agree... Even a foamie is dangerous and the weirdest fluke, with odds less than being struck by lightening, could be fatal... With that said it is a reach IF all precautions are taken, like no spectators in the flying area and a safe zone clearly marked for spectators.

More could go wrong at a flying field for the larger planes than a F3P in a gym...

I suspect people are very sensitive given the recent loss of a RC Heli Pilot.

The other thought is if they approve F3P, then who is right behind you with a Heli... I would be willing to bet a Public school would error on the side of caution... They don't want to be the next school getting unpopular attention...
