aeronaut Z-Spinner (CN) 35mm
The spinner series for top aerodynamic performance.
The Z-spinners combine the advantages of the CN spinners (cool nose with cooling air openings) and the offset Z centre sections. Thanks to the angled aluminium centre sections, the folding propeller blades fit even closer to the fuselage and thus ensure less drag during gliding. The spinners with the centre pieces are designed for slim E-glider fuselages, but can also be advantageous for wooden fuselages in box construction, for example, if they are sanded round.
The centre pieces of the spinner sizes 32-42mm are interchangeable, e.g. 38mm spinner caps can be operated with the centre piece of the 42mm spinner. These combination options offer further optimisation potential, as they allow finer tuning to the respective fuselage.The 30mm spinner has its own centre piece, which cannot be combined with the other spinner caps.
The Z-spinner contains a spinner cap (diameter 30mm) made of white plastic (very easy to paint), milled aluminium centre piece with integrated holder for clamping cone, special prop rubber for folding the propeller blades, mounting screws for spinner cap and propeller blades.
The diameter of the spinner cap is 35 mm. The centre distance (d) of this spinner is 32 mm. This means that the diameter of the propeller blades is reduced by 10 mm (0.39"). Example: A propeller with a diameter of 12" effectively has a diameter of 11.61" at this centre piece (the size specifications for folding propellers always refer to the use of a centre piece with centre distance d=42 mm).
IMPORTANT: An additional clamping cone must always be purchased to match the motor shaft used. You can find these in the section: Clamping cone for Z-spinners
