Aerodynamic Glider EfficiencyStreamlined performance for sailplane fuselages
The Aeronaut Z-Spinner: 30mm combines advanced motor cooling air openings with angled aluminum center pieces for ultimate RC glider performance. Designed for slim electric sailplanes and rounded wooden fuselages, this folding propeller spinner drastically reduces aerodynamic drag during glide phases.
Precision Engineered SpinnerMaximize your glider performance and glide duration
Upgrade your electric sailplane with the high-precision Aeronaut Z-Spinner: 30mm. Featuring a cranked aluminum center section, this spinner allows folding prop blades to lie flush against the aircraft fuselage, significantly minimizing drag while soaring. The integrated cooling channels direct continuous airflow straight across your brushless motor setup, preventing thermal buildup during high-power climbs. Supplied with a paintable white cap, internal clamping cone holder, mounting hardware, and protective prop rubber, the Aeronaut Z-Spinner: 30mm delivers an ideal blend of efficiency, customization, and reliability for competitive and sport glider pilots alike.

Frequently Asked QuestionsEverything you need to know
What fuselages fit the Aeronaut Z-Spinner: 30mm?
The Aeronaut Z-Spinner: 30mm is optimized for slim e-sailplane fuselages, but it can also be used on traditional wooden box-construction fuselages if the nose is properly rounded.
How does the Aeronaut Z-Spinner: 30mm affect my folding propeller size?
Because the center distance of the Aeronaut Z-Spinner: 30mm center section is 25mm, the total effective propeller diameter will be reduced by 16mm (0.67 in.) compared to standard 42mm center pieces.
Is the center section of the Aeronaut Z-Spinner: 30mm interchangeable with larger Aeronaut spinners?
No, the 30mm Aeronaut Z-Spinner utilizes its own dedicated center piece and cannot be interchanged with the larger 38mm, 40mm, or 42mm Aeronaut spinner caps.
