that's awesome, what colors where?
Blue on the front arms, red on the rear.
My F450 is built with white arms in the front and red on the rear. Since the red arms are easier to see than the white, it messes with me a little bit, by my thought was that red = rear, just like brake lights.
Now that I've added the blue & red lights, it makes sense.
I have one LED strip (6 LEDs in length) on the bottom of each arm.
I have a long strip of blue LEDs following the perimeter of the front two motors from arm-to-arm. The LED strip starts at the outside perimeter of one motor then wraps all the way around the the outer perimeter of the other front motor.
Pretty much have the same thing on the rear but with red LEDs.
The sides are a bit darker than I thought they would be, but it seems to work well as I can see enough of blue & red on the front/rear arms while looking at the side of the F450. If anything, I might add a short strip of yellow or a different color on the sides. I don't want to get too carried away though, and I think it is best to have as much contrast as possible, and the current red/black does that well.
At 4S, the LEDs put out a good amount of illumination toward the ground too. Not only does it look cool, but it gives me a good sense of where the ground is at night.
I'll try to take some pics, but don't think the gopro can pull off great night shots.
