42mm Cap Size
Optimized for slim electric sailplanes
Reduced Glider Drag
Folds blades closer to fuselage
Milled Aluminum Center
Durable center section performance
Aerodynamic Glider SpinnerMaximize efficiency on your sailplane
The Aeronaut Z-Spinner 42mm combines active motor cooling with an ultra-streamlined profile to enhance your RC glider performance. Designed specifically for electric sailplane fuselages, it features angled aluminum center arms that tuck folding propeller blades tight against the airframe, significantly reducing drag during thermal soaring.
Precision Electric Sailplane HubEngineered low-drag hub design for thermal soaring
Upgrade your e-sailplane performance with the high-precision Aeronaut Z-Spinner 42mm. Combining the thermal advantages of cooling air openings with cranked Z aluminum middle pieces, this spinner allows folding propeller blades to lay flatter against the fuselage than conventional spinners. Built with a paintable white plastic cap and a milled aluminum hub, the Aeronaut Z-Spinner 42mm allows modular interchanging of center pieces between 32mm and 42mm sizes to achieve a seamless custom fit on slim or rounded motor noses.

Frequently Asked QuestionsEverything you need to know
What types of aircraft are compatible with the Aeronaut Z-Spinner 42mm?
The Aeronaut Z-Spinner 42mm is designed primarily for slim electric sailplane fuselages, but it also works exceptionally well on rounded wooden box-construction noses.
How does the center distance of the Aeronaut Z-Spinner 42mm affect folding propeller selection?
The center distance (d) of the Aeronaut Z-Spinner 42mm is 36mm, which effectively reduces your folding propeller diameter by 6mm (0.24 in.) compared to standard 42mm center section hubs.
Can I mix and match parts on the Aeronaut Z-Spinner 42mm?
Yes, center pieces for Aeronaut Z-Spinners between 32mm and 42mm are interchangeable, allowing you to pair a 42mm center piece with a 38mm cap for precise alignment.
