Precision milled center piece
Streamlined Sailplane EfficiencyAerodynamic Drag Reduction for Gliders
The Aeronaut Z-Spinner: 32mm combines the cooling performance of a CN open-nose design with an angled aluminum center section for elite gliding performance. Specially engineered for slim e-sailplane fuselages, this high-efficiency RC folding propeller spinner folds blades tightly against the body to significantly lower air resistance.
Precision Cooling & FitEngineered Folding Propeller Hardware System
Designed to optimize competitive and recreational RC gliders, the Aeronaut Z-Spinner: 32mm features a durable white plastic cap that can easily be painted to match your aircraft scheme. Its precision milled aluminum center piece features an integrated clamping cone holder and a 28mm center distance, effectively reducing standard folding propeller diameter by 14mm for fine-tuned power plant setup. Furthermore, components across 32mm to 42mm Aeronaut spinner assemblies are interchangeable, granting endless tuning flexibility for your brushless motor system.
