60mm CW CCW Propeller Pair for 8520 Coreless Motor 1mm Shaft Orange

Specifications

• Propeller Length: 60mm
• Shaft Hole Diameter: 1mm (Tight press-fit)
• Rotation: 1x Clockwise (CW), 1x Counter-Clockwise (CCW)
• Compatible Motor Type: 8520 Coreless DC Motor
• Material: High-strength lightweight polymer
• Color: Orange
• Application: Micro Quadcopters, Mini Drones, RC Planes
• Mounting Type: Direct drive (friction fit)

Minimum hardware

• 8520 Coreless DC Motor (1mm shaft)  required to mount the propellers; the 1mm hub is explicitly designed for a tight friction-fit on this specific motor class.
• Micro Drone Flight Controller  required to actively manage motor RPMs, as manual throttle control is impossible for quadcopter stabilization.
• 3.7V High-Discharge LiPo Battery  to provide the immediate, high burst current that coreless motors draw when spinning 60mm props under full load.

Safety & Installation Warnings

• High RPM Hazard: 8520 motors spin at extremely high speeds. Wear eye protection during initial bench testing.
• Shaft Fragility: The 1mm shaft on an 8520 motor is delicate. Always press the propeller straight down. Bending or twisting during installation will permanently snap the motor shaft.
• Thrust Direction: Installing a CW prop on a CCW spinning motor will generate downward force (pushing the drone into the ground) instead of lift.

Accessories Included in the Box

• 1× 60mm Clockwise (CW) Propeller, Orange
• 1× 60mm Counter-Clockwise (CCW) Propeller, Orange

Frequently Asked Questions

• Are these propellers compatible with 716 or 720 coreless motors?
  No, they are specifically tuned for the RPM and power output of 8520 class motors, though they will physically fit any motor with a 1mm shaft.
• Will this fit a motor with a 0.8mm or 1.2mm shaft?
  No, the hub is precision-molded exactly for a 1mm shaft to ensure a tight friction fit without splitting.
• Can I use these on a custom 3D-printed drone frame?
  Yes, as long as your frame design allows for at least 65mm of clearance around the motor mount to accommodate the blade sweep.
• Do these work for RC airplanes or just quadcopters?
  They work excellently for lightweight RC airplanes and gliders as direct-drive thrust propellers when paired with an 8520 motor.
• How much thrust does a 60mm propeller generate on an 8520 motor?
  While it depends on your battery and motor quality, a 60mm prop typically generates between 35g to 45g of thrust at full throttle on a 3.7V system.
  
• Will a 60mm propeller draw more current than a 55mm one?
  Yes, the larger blade surface creates more air resistance, causing the coreless motor to pull slightly higher peak current.
  
• What size LiPo battery should I use with these propellers?
  A high-discharge 3.7V (1S) LiPo ranging from 300mAh to 500mAh provides the best balance of flight time and weight.
• How do I install the propeller without bending the motor shaft?
  Pinch the motor casing tightly with one hand, align the propeller hub perfectly vertical over the shaft, and press straight down until seated.
  
• Do I need glue to keep the propellers on the motor?
  No, they rely on a tight mechanical friction fit, and using glue will ruin the motor by locking up the delicate top bearing.
  
• How do I safely remove a broken propeller?
  Use a specialized U-shaped metal propeller removal tool or slide fine tweezers under the hub and pry upwards evenly.
• How do I know which propeller is Clockwise (CW)?
  Look closely at the blade pitch; the raised, leading edge of a CW propeller will cut into the air when turned to the right.
  
• What happens if I put a CCW propeller on a CW spinning motor?
  The propeller will generate reverse thrust, pushing your drone downward into the ground instead of lifting it into the air.
  
• Do I need to configure anything in Betaflight for these props?
  You only need to ensure your motor mapping and rotation directions in Betaflight match the physical placement of your CW and CCW props.
