The problem I just realized, may be that the spinners I have may be the problem here as they may be for electric only. They are plastic with aluminum backplates and have no raised center where only the prop hub would contact the backplate as in a plastic Du-Bro backplate/spinner. The props I just got are all XOAR wood props, very popular with my club and others. Having just got these, I'll ask around the club to see if there's a difference between electric backplates and nitro/gas backplates. So far I haven't found much on the net to clarify that other than some "electric only" spinners for sale. This is what got me to wondering.
