MPI 29mm (1.14") E-Spinner Bar-Stock Aluminum Shiny Finish

Light weight design made of high quality aluminum bar-stock. Polished to mirror finish. Comes with 2.3, 3.2 and 4mm collets.

Fits 2.3mm, 1/8" (3.2mm), 5/32"(4mm) shaft diameter. Weight: .26oz(7g) for Cobalt 400, Speed 400 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.

SKU Number: MPIPS29
