I love that type of spinner. I pick one up when I can for my Coxes, I'd like to replace all of them with studs and spinners. The 1/2A ones we get are either knockoffs or genuine Ron Valentine products.
I don't know if they make ones to fit a Norvel shaft. Probably so. I just use long bolts on them. 3mm I think.

You can tap them out to 3mm for the .049 and .061 Norvels they are a bit heavy but do look great.
I particularly like them with the APC 6x4 (hub dia is 1/2A size) and the Norvel .074 requires a 4mm tap but weight is not an issue with the .074 that engine has no problem spinning the additional mass.

Did you check out the HP/Watt/Thrust/MPH calculator? its very good and the only one I will use now.
I keep a icon on my desk top now for fast reference. Thumbs Up
