Milled Center Component
Streamlined Glider PerformanceAerodynamic Precision for Sailplanes
The Aeronaut Z-Spinner 38mm blends cooling technology with a unique cranked center piece designed specifically for high-efficiency RC e-sailplanes. By allowing folding propeller blades to rest tightly against the fuselage, this folding propeller spinner significantly reduces aerodynamic drag during powered glide phases.
Advanced Aero EfficiencyEngineered for Peak Glider Performance
Designed for demanding sailplane pilots, the Aeronaut Z-Spinner 38mm features an innovative angled aluminum middle piece that brings prop blades closer to the fuselage contour than traditional setups. Combining the airflow advantages of a cool-nose CN spinner with a precision-milled CNC aluminum hub, it keeps your electric motor running cool while minimizing overall drag. The high-impact 38mm white plastic cap can easily be painted to match your scale RC glider paint scheme, and the interchangeable center pieces allow fine-tuned adjustment for a tailored fit across various fuselages.

Frequently Asked QuestionsEverything you need to know
How does the Aeronaut Z-Spinner 38mm reduce air resistance?
The Aeronaut Z-Spinner 38mm features angled aluminum middle pieces that pull folding propeller blades tighter against the fuselage, significantly lowering drag during gliding.
What effective diameter change occurs with the Aeronaut Z-Spinner 38mm?
Due to its 32mm center distance (d), the Aeronaut Z-Spinner 38mm reduces total propeller blade diameter by 10mm (0.39 inches) compared to standard 42mm center sections.
Can the cap on the Aeronaut Z-Spinner 38mm be custom painted?
Yes, the white plastic spinner cap included with the Aeronaut Z-Spinner 38mm is designed to easily accept paint so you can match it to your aircraft's trim scheme.
