This Aloft Alloy folding prop spinner has a 30mm diameter and uses a special compact collet. We offer more sizes, but they have a slightly different collet and are not interchangeable with the units on this page.
Collets are sold separately, this allows us to deliver you the best possible price. Just select the collet that that fits the motor shaft size on your plane. For example, your motor has a 5mm shaft, just add the 5mm collet for your spinner.
