Blade Tracking LED's

Postby bryancobb » Wed Mar 05, 2008 3:11 pm

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.
