As far as I'm concerned, small RPAs should not be able to operate above above 100' AGL within 1nm of an aerodrome, or above 500' within 3nm of an aerodrome.
Outside those limits, I don't care.
I just don't want to be on a one mile final at 300' in a 300k lb airplane and have a quadcopter go zipping past me...
Perfectly understandable. I'm sure there is no shortage of idiots out there who aren't capable of operating these without creating problems for others.
How long does recharging the battery take?
A little over an hour. I'd like to have several batteries on hand but at $170ea the one spare I have is probably going to be it for awhile.
