One of the many features is the solenoid controlled brushes that drastically
reduce wear on the brushes.

Paul, after giving this part some thought, the traces need to be brought in
as close as possible to the center axis. I was looking at a similar system
with a 2" diameter shaft and the traces were on the shaft. This reduces the
circumference and speed of the point of contact considerably.

Thanks for you thoughts on this Chrissi.
That is a lot harder to do I think. I will take a look at an alternative
design. This is what Hoffman and MT do. Ivo does it differently. (On the shaft.)
None have the solenoid engagement that this design does so the brushes
are always in contact. In our case the brushes only contact the slip
rings for seconds. Only when changing pitch. It is not a constant speed
prop that would require the brushes to be in contact all of the time.
