Precision molded from tough engineering nylon, these great SIG spinners are available in five brilliant colors and seven of the most popular diameters.
What really sets the SIG spinners apart from the competition is the fact that they are designed to accept APC propellers, (typically used with specific diameters), without the need to carve out the prop exits! This means that modelers now have spinners that need no modification for use with the most popular line of propellers in the U.S.
Who else but SIG!
