So, it seems you are unhappy with the design, which does not sound as high quality as tru-turn of course, but what kind of operational problems have you had with this spinner? I have heard some like them and some don't, but don't really know what kind of problems are inherant in this design.
Has anyone had any serious problems? Like melting due to heat from 4 stroke engines? Or being badly out of balance? If so, what is the best technique this particular type can be balanced without a center bolt hole to use on a prop balancer?
