Some pointed type plastics here at RJL, Mecoa:

These are aluminium back plate types with a capture ring for the plastic.

ok, First in line is the typical cheezy and cheap spinner that is included with most Arfs. Next in line in the middle is the CB associates spinner that I linked above and sold by RJL, Mecoa. Last on the right is a True Turn all aluminum and the cadilac of spinners.
Please note the all plastic ARF type on the left does not have a 'capture ring' to take the centrifugal loads such as rough starter usage. The CB partial plastic and the True turn both have this all important feature. A lack of this feature on the plastic is what I feel is a major contributor to exploding spinners with rough starter usage and not the formula and thickness of the plastic.
Acrtually the CB is only slightly heavier than the all plastic and its not the plastic that causes the difference but is the long adapter nut. Note I weighted all three with all the appropriate nuts, adapters and washers that would be used with each type.
My best recommendation to anyone is to always avoid the all plastic. If you must use a less expensive plastic then the CB is preferable but my choice is always the all aluminium,. I use both the Truturn but also The Dave Brown vortach spinners I believe they are called and are less expensive.

Ah ha I did not enlarge the OP's photo, that's the problem when the fellows give insufficient information. Note Scale that the electric prop spinner you linked has a Capture ring, that's a good thing even on an electric.
As far as the CB spinners being to heavy well look at the weights of the CB and the cheap plastic of the same size that I show in the photos. the CB is only .4 tenths of an ounce heavier and that is primarily because of the superior single bolt attach method.

My Feedback: (-1)
I'm just happy that the Mecoa site has now been posted a couple of times now with the CB spinners, I thought CB was no longer with us. I have only used one on a glow engine but I like them on my gas engines that only get hand flipped. I had a big box of them from years past and have finally used them all up. I may have several of the back plates still on hand?
I thought they were heavy too until John brought out his scale. And people tell me I have too much time on my hands!!
