This Irvine spinner is finished in a bright coloured chrome finish to help your model really stand out! With a lightweight, machined aluminium backplate, you know this is a high quality spinner as soon as you see it. With no backplate flex, it will run true and stay in shape season after season. It also has a unique 'easy-trim' feature where the material around each propeller cutout is thinned to half the thickness of the surrounding material to make trimming to suit different blade shapes easy.
