Some good points Gord,

I disagree only slightly with the "exposure time" pov though. The high speed pass carries far more kinetic energy and far more "potential area coverage" so the two cannot be compared directly based on time exposed.
Also,
If I have a radio glitch while hover, my pcm system will simply shut down my throttle and I'm left with a broken plane almost directly under where I was hovering. If I'm doing a high speed pass however....

When I fly a scale plane I have a lot of time into, I simply pick a quiet time or as for some free airspace time....

I also, am not against either maneuver in question and think comon sense should prevail. As for hovering in front of other pilots; bad form! Someone might think mistake them for performing the maneuver and me endlessly flying circuits.

Seriously, when I hover it's always toward the outer limit of the runway and always directly in front of me. The torque rolls (when I can manage them) do drift with the wind though but, I always bail out before getting any closer than mid runway. Courtesy is prime, I clear out when someone else wants centre stage or needs the runway. Same goes when I fly heli at the field, no problems or complaints so far. There were a few nervous nellies when I introduced helis to the flightline but, the last couple years they've been accepted as equals (as they should be).
