Can anyone tell me how a dynamic prop balancer works? I have heard that it
involves an accelerometer to detect vibration, but it what do they use to detect
the prop position to correlate with that accelerometer? Could it be an optical
pickup from a mark placed on the prop? Or perhaps a pickup from the magneto?
Although a mag pickup would be ambiguous by 180 degrees, I think. I was just
brainstorming on how I might design one from scratch.

I believe an optical pickup is placed on the cowl with a reflector on
one of the prop blades.
