MPI 44mm (1.73") E-Spinner Reverse Pitch Bar-Stock Aluminum Brushed Finish

Fits 5/32"(4mm) shaft diameter. Weight: .85oz(24g) 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.
