The spinner series for aerodynamic peak performance.

The Z-spinners combine the advantages of the CN-spinners (Cool Nose with cooling air openings) and the angled Z-centerpieces. The angled aluminum centerpieces allow the folding propeller blades to hug the fuselage even closer, resulting in reduced air resistance during gliding. The spinners with the centerpieces are designed for slim electric glider fuselages but can also offer benefits when used with wooden fuselages built in box construction, provided they are rounded.

The centerpieces of spinner sizes 32-42 mm are interchangeable, allowing for, for example, 38 mm spinner caps to be used with the centerpiece of the 42 mm spinners. These combination options provide further optimization potential, enabling finer tuning to the respective fuselage. The 30 mm spinner has its own centerpiece that is not compatible with the other spinner caps.

The Z-spinner includes a spinner cap (diameter 30 mm) made of white plastic (very paintable), a machined aluminum centerpiece with an integrated mount for the tension cone, a special prop rubber for folding the propeller blades, and mounting screws for the spinner cap and propeller blades.

The diameter of the spinner cap is 35 mm. The distance between the axes (d) for this spinner is 32 mm. This means that the diameter of the propeller blades is reduced by 10 mm. For example, a propeller with a diameter of 12 inches effectively has a diameter of 11.61 inches at this centerpiece.
