Key features
- Low-noise quiet flight - aircraft noise is reduced with up to -3.0dB representing almost 50% noise power reduction. Lower pitch sound is less noticeable and disturbing. (Nominal values compared to DJI OEM propellers.)

Manuals
Diameter
The propeller Diameter is equal to the diameter of a circle drawn by the propeller tips during rotation. For 2 blade propellers the diameter is equal to the length of the propeller from tip to tip. For 3 and more blades, the diameter can be derived by 2x the length of the single blade (from tip to center).
Pitch
The Pitch indicates the distance a propeller would move forward in one revolution. The higher the pitch the more aggressive the angle of attack.
Tractor, Normal, Standard
Direction of rotation is established when a propeller is rotating counterclockwise (CCW), as seen by an outside observer standing in front of the propeller and looking at it.
APC props without a designation of standard
Master Airscrew designate with "N"
Reverse (R) - Pusher
also known as P-type, direction of rotation is established when a propeller is rotating clockwise (CW), as seen by an outside observer standing in front of the propeller and looking at it.
APC designate with "P"
Master Airscrew will designate with "R"
Shaft Diameter
The shaft diameter is equal to the size of the orifice at the center of the propeller where the motor shaft is connected. Since shaft diameters differ from engine to engine, some propellers are manufactured with 2 shaft diameters (pre-drilled on the back) for easy adaptation. Some propellers, as the 3 Blade and Electric Only Series, include Adaptor Ring Sleeves which can adjust the the shaft diameter to several inch or mm sizes.
Hub Thickness
The Hub Thickness is usually used to determine the necessary engine shaft length so there is enough space for connecting the propeller and the cap or the spinner.
APC use the following additional modifiers to identify their props:
- E Thin Electric or Electric (electric only)
- F Folding Blade (electric only)
- MR Multi-Rotor (electric only)
- SF Slow Flyer (electric only)
- R Reversible ESC (electric only)
