Got a spinner from GP that is a little differant from what I am used to. I have used many smaller nylon backed spinners. But I wanted a 3", and nylon that large I have heard is not as good as aluminum. So, I compromised (Due to my budget), and got a nylon/aluminum backed 3" spinner by Great Planes. Which of you have used them? And are they ok? Is there any inherant problems with this type?
