Blade Tracking LED's

Hey Folks:
I built a set of these a couple of years ago. And they WORRRKKKK!!! You can track the blades, in flight, at night. You can even identify which blade needs bearing replacement.
I had 2 blades that followed the same tip bath within about 1/8". Then one blade flew 2 inches high on the advancing side and 1" low on the retreating side.
After a LOT of scratching my head and trying to figure out WHY, I just gave up. Then I sent this drawing to my friend who has a B-2. He made him a set and had almost the identical situation.
He replaced the bearings in the ONE blade that was flying erratically. Now they all three track well.
