Very versatile folding propeller hub for multiple shaft sizes.
Folding Propeller Spinner 44mm with 3.17, 4 & 5mm Shaft
Prop Mount Bolt: 2.2mm
Prop mount Flange: 55mm (bolt centre to centre)
Most of my folding props blades will fit these hub sets if you cannot find one with the right shaft size and diameter.
