Precision Glider PropulsionHigh Efficiency Folding Propeller Pair
The Aeronaut 12.5x9 CAM Folding Blades deliver outstanding performance and efficiency for electric sailplanes and high-performance RC gliders. Engineered with carbon fiber reinforced composite materials, these folding propeller blades provide superior rigidity and minimal aerodynamic drag during unpowered thermal soaring.
Advanced Aerodynamic Sailplane BladesEngineered for Ultra-Low Drag Soaring
Designed to optimize electric flight efficiency, the Aeronaut 12.5x9 CAM Folding Blades feature an advanced blade profile tailored for seamless folding against narrow or box-shaped glider fuselages. Constructed from premium carbon-reinforced plastic, these blades offer high torsional stiffness while remaining extremely lightweight. The specified 12.5x9 dimensions are calculated using a 42mm center yoke, fitting standard 8mm blade root spinner assemblies such as the Aeronaut CN precision spinner range. For safe operation with high-torque brushless motors, always utilize a soft-start ESC configuration and adhere strictly to the maximum recommended speed limit of 13,000 RPM.

Frequently Asked QuestionsEverything you need to know
What is the maximum RPM rating for the Aeronaut 12.5x9 CAM Folding Blades?
The Aeronaut 12.5x9 CAM Folding Blades have a maximum safe operational limit of 13,000 RPM. Always verify motor RPM and use an ESC soft-start setting to avoid over-speeding or mechanical strain.
What root size spinner hub do the Aeronaut 12.5x9 CAM Folding Blades require?
The Aeronaut 12.5x9 CAM Folding Blades feature a standard 8mm root width and fit all folding propeller spinner yokes designed for 8mm blade roots, such as Aeronaut CN spinners.
Are the Aeronaut 12.5x9 CAM Folding Blades sold individually or in pairs?
The Aeronaut 12.5x9 CAM Folding Blades come packaged as a factory-matched pair containing two individual propeller blades.
How does middle piece size affect the dimension of the Aeronaut 12.5x9 CAM Folding Blades?
The specified 12.5" diameter and 9" pitch are measured using a standard 42mm middle piece (yoke). Using a wider or narrower middle piece will proportionally increase or decrease the final overall diameter and effective pitch.
Can the Aeronaut 12.5x9 CAM Folding Blades be used on narrow glider fuselages?
Yes, the Z-shape design of the Aeronaut 12.5x9 CAM Folding Blades brings the blades closer to the fuselage when folded, significantly reducing aerodynamic drag on narrow or box-shaped electric gliders.
