Aeronaut 42mm Precision Spinner for 4mm shafts

Aeronaut precision spinners come with an aluminium backplate, a black spinner cap and a clamping clone for various shaft sizes. These spinners do not come with a centre piece (or yoke) for attaching folding propeller blades, but these are available separately.
It is usually appropriate to use a centre piece 2mm larger than the backplate. For example with a 40mm spinner, one would use a 42mm centre piece.
The M8 shaft of the clamping cone also features a front bore, for securing the spinner cap with the included screw.

For compatibility, we recommend not to mix spinners and folding propeller blades from different manufacturers.
