Light weight design made of high quality Brushed Aluminum Bar Stock Finish. Comes with 4mm collet.
Fits 5/32"(4mm) shaft diameter. Weight: .40oz(11g) for Cobalt 05, 15, 20, brushless motors. ProSpin spinners are made from high quality bar-stock for strength. They won't crack like cheap cast aluminum spinners do. ProSpin spinners are also 30% lighter than cast aluminum. All spinners include a shaft bushing, prop nut, and bolt. All spinners are polished.
Notes on Ordering:
1. Find out the size of the prop nut you need.
2. If you need a different prop nut, you need to order it separately.
3. Some engines, i.e. Saito engines, require a bushing that is larger than the nut.
