Very versatile folding propeller hub for multiple shaft sizes.
50mm Alloy Folding Propeller Spinner with 4mm, 5mm & 6mm Shaft adapters
Prop Mount Bolt: 2.3mm
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.
