If you are planning on using an apc 11x5 prop you most likely have fitment problems with a plastic spinner that is in the 2" - 2 1/2" range as the prop blades are wider than the cutout in the spinner. If you still want to use the plastic spinner you will likely have to trim the opening a bit wider to get the actuall nosecone spinner to fit onto the backplate.

As far as using plastic spinners with electric starters there isn't a problem as long as the insert in your starter is in good condition. I've been using plastic spinners for a little over 2 years with no problems. My biggest problem using plastic spinners on my spa3dt was that while learning to do basic 3d manuevers (and several dirtnaps later) I would crack or bust the spinners and that was getting expensive so I moved up to a du-bro aluminum prop nut...they work in electric starters without having to turn the cone insert around and work great.
