I was considering a Suzuki Motorcycle generator for my Aircraft application is has the internal windings held on the outer motor casing, with the outer shell connected to the rotating mass. The outer motor casing which holds the inner core also has the CKP pick-up while the rotating shell has the timing wheel. Very neat and simple.

However is a CKP pick-up?

George, I'm not completely sure that I'm understanding you.

It has a wound rotor (the rotating part) that is on the outside?
The stator (the stationary part) is attached to the engine?
What is a CKP?

I wanted to go the permanent magnet route in order to avoid slip-rings and brushes and such.  It's modestly heavier, though not by a large margin; however, it is a much simpler setup...electrically and mechanically.  Even the regulator is a stone simple affair.

I'll experiment with getting a VR sensor signal from the flywheel once I get my engine running.  I don't need to pick a signal up from there, but I think it will be really easy.
