3D at your flying field
As long as those doing the 3D are sensible, there shouldn't be a problem. We only have one guy who can really do it (hover). He doesn't do it over the runway and everyone else just avoids the area where he is. The grumpy old man contingent will complain about ANYTHING new. Our meetings are dominated by the grumblings of this group....and they haven't flown an airplane in years. Oh well.
