Ok, one more thing...a question remembered from an email conversation several months ago. Why are the contact pieces different size in the red cap? Well, for one thing the coil-in-cap rotor has a slightly wider tip. And for the other thing, the contact pieces in the non-coil-in-cap model sit closer to the center. The diameter of the travel circle on the non-coil-in-cap model is roughly 3.2" and the diameter of the travel circle in the coil-in-cap model is roughly 4.2". Different geometry.
