Man, the size of those things, one of them smack ya, you’d end up in the next county.. I’m sure big birds will be able to fly around them safely.

Yeah, a 5Kw would actually be biting off a little more than I could chew... probably more like a 2Kw. That’s roughly the equivalent of a 15-amp electrical circuit. Roughly.
As far as birds — most of them would avoid it, and the ones that didn’t would probably be doves, so I’d just pick ‘em up and put ‘em in the freezer. (And bury the occasional spotted owl or golden-cheeked warbler... ssshhhhh...) :-)
They don't see the blades coming. Tip speed can be over 100 mi/h.
