Think I saw a couple of drones flying really high together over the willamette valley. I might be wrong though since there were two. But it is country fair this weekend. Thoughts..?
An MQ-1 Predator has a ceiling of 25,000 and can fly 134 MPH. At that altitude, they would be hard to spot at 27 feet long and a wing span of 55 feet.
I mainly see drones when I'm working up in Portland, the Pearl District is full of them... Oh wait, the OP was talking unmanned remote controlled aircraft and not hipsters.
I want some of those drone loads GOG don't hold out on me... how much for a box? And 1330 fps seems a little light do you have anything in the 15,000 fps range?
