Weighed my new CH single bolt adapter, 85 grams. 3 oz on the nose. That includes the four mounting screws, prop washer and nut plus a new prop hub nut and washer. Subtract the weight of the original prop bolt, washer and four mounting bolts and I don't think there's much weight gain. (I'm waiting for my engine)
The machining of the adapter is excellent and it has been tapped for a spinner bolt saving the cost and weight of an additional adapter! When I receive my engine I'll check the runout with and without the new adapter
Mine came today an after grinding down my thinnest wall socket it still wouldn't fit in the hub have to drill out the hub to accept the socket, but this will still be better than drilling those 4 prop bolts. thanks Valley View
This is the person who had the CH single bolt adaptor and who the comments were referring to
