My father was flying in his real helicopter the other day at 1500ft and a yellow quadcopter came within 50ft of him. My question is "are there any factory yellow quads that can achieve 1500ft?" I am aware people paint their drones. He said it was as big as my inspire 1 and it wasn't a phantom. I showed him the parrot and he said it wasn't that. He said he didn't even notice the drone until it looked like a hi-lighter marker whizzing by. It would of been too late for corrective action if it was head on. I bet the pilot of the UAS shit themselves!
