How do the lights work out side after dark...they work. Problem is depth perception focused on 1 white, a red, and a green. The white flashes so bright, it blinds you at eye level, and it's a little tough to judge distance, speed, direction, and altitude. Flew it eariler (around dusk with zero wind), and that was GREAT. Just kinda cruised around the yard. When a slight breeze come up, it would climb to about 10-12ft from waist high. At dusk, the lights are great because everything starts to loose color so the lights stand out but you can still see the heli. No way I'd just put it up in the dark and fly. I just hovered nearly stationary after dark. Thought you guys might be interested in that little experiment.
