Aeronaut Centrepieces

These centrepieces are made from machined aluminium and provide the ideal yoke for your folding propeller. They have an 8mm hole which matches many types of prop adaptors and precision spinners, and the cheeks are 8mm apart to accept most folding prop blades.

The blades pivot on 3mm bolts with a smooth shaft to allow smooth swivelling, and which also come with nylock nuts for firm attachment.

Remember, when working out prop sizes, that Aeronaut assume a 42mm centrepiece, whereas Graupner assume a 32mm centrepiece. You can vary prop size by varying the size of the centrepiece.

The -5 degree and +5 degrees centrepieces also vary the pitch by about 2 inches, so you can vary the pitch by using these centrepieces.

Aero-naut have released large parts to match the size of the current crop of electric models and motors - prop holders to fit 8mm and 10mm motor shafts and centrepieces to match (below) - as well as Cool Nose Spinners up to 70mm diameter

** Also -if you want a small centrepiece (pusher situation for example), 34mm centrepieces are now available that fit Cool Nose 30mm spinners - they have a tapered hole in them and any collet from a prop adapter will fit them! Use with any collet and do away with the backplate.
I have these aluminium bushes (right) courtesy of Kim & Brad Turner - produced on a CNC lathe. They are 8mm outside diameter, and 6mm inside diameter. They fit neatly in to the centrepieces so that the centrepiece will fit a 6mm prop holder or shaft. These are available for $2.00 with any purchase - just ask!
