Aerodynamic Sailplane ThrustHigh Efficiency Folding Propellers for Gliders
The Aeronaut 18x11 CAM Folding Blades offer exceptional efficiency and aerodynamic performance for electric gliders and sailplanes. Engineered with advanced carbon-fiber reinforced materials, these RC airplane folding propeller blades fold snugly against narrow or box-shaped fuselages to dramatically cut down on drag during soaring flight.
Precision German EngineeringMaximized Performance for Electric Flight
The Aeronaut 18x11 CAM Folding Blades represent a high-performance benchmark in electric motor glider propulsion. Utilizing a specially optimized profile in the root area, these carbon folding propeller blades fit standard 8mm root spinner yokes, including Aeronaut CN and Z-spinners. When paired with a 42mm middle piece, the 18x11 sizing yields maximum thrust and efficiency, while allowing the blades to fold nearly flush against the airframe. Designed for safety and long-lasting durability, the Aeronaut 18x11 CAM Folding Blades require a soft-start ESC program to ensure smooth motor spool-up without overstressing the blade root.

Frequently Asked QuestionsEverything you need to know
What comes in the package with the Aeronaut 18x11 CAM Folding Blades?
Each package contains a factory-matched pair of two Aeronaut 18x11 CAM Folding Blades designed to operate together on a single folding propeller yoke.
What root size do the Aeronaut 18x11 CAM Folding Blades require?
The Aeronaut 18x11 CAM Folding Blades feature a standard 8mm blade root width, making them compatible with standard folding propeller spinners and yokes designed for 8mm roots.
How does middle piece size affect the diameter of the Aeronaut 18x11 CAM Folding Blades?
The specified 18x11 size is calculated using a standard 42mm middle piece (yoke). Using a larger middle piece increases both overall diameter and pitch, while a smaller middle piece reduces them.
What material is used to construct Aeronaut 18x11 CAM Folding Blades?
Aeronaut 18x11 CAM Folding Blades are molded from high-grade plastic composite reinforced with carbon fibers for increased stiffness and tensile strength.
Are there motor control requirements for using Aeronaut 18x11 CAM Folding Blades?
Yes, Aeronaut 18x11 CAM Folding Blades must always be used with an Electronic Speed Control (ESC) programmed with a soft start to prevent rotational shock and root stress during spool-up.
Which spinners are recommended for the Aeronaut 18x11 CAM Folding Blades?
While the Aeronaut 18x11 CAM Folding Blades fit any 8mm root folding spinner system, optimal aerodynamic performance and tight folding are achieved when paired with Aeronaut Z-spinners (CN).
