One more thing regarding the prop adapter: CH will ask if you want a single or multi-bolt hold down for the prop. The single has a shaft that runs through the center of your prop. It also has a threaded ID which you can use to hold your Byron spinner in place. It also comes with a large prop nut washer. I had some guys in our prototype shop cut a groove in this washer that matched the dimensions of the spinner provided by Byron. So, the bolt through the center of spinned threads into the adapter and the back of the spinner sits in the groove cut in the prop washer.

I don't have a picture of this setup - can get one if you'd find it helpful.
