APC Props Prop 4X4.5E-B4 2CW & 2CCW RC Aircraft Propeller - APC04045E-B4

The APC Props 4x4.5E-B4 (style code APC04045E-B4) is a set of four electric RC aircraft propellers designed for multirotor applications, supplied as two clockwise and two counter-clockwise rotating props. APC is a well-regarded name in the RC propeller market, and this balanced four-prop pack is matched to the paired rotation requirements of quadcopter and multirotor frames.

Key Features

• 4-inch diameter with 4.5-inch pitch, sized for small to mid-range electric multirotors
• Supplied as two clockwise (CW) and two counter-clockwise (CCW) props, covering a full quadcopter set in one pack
• Designed for electric power systems — the 'E' designation indicates optimised pitch geometry for motor-driven rather than glow or petrol powerplants
• APC's consistent moulding quality means each prop in the set is well-balanced out of the pack, reducing vibration in flight
• Lightweight construction suited to the thrust and RPM demands of small electric multirotor motors

What's Included

• 2 x clockwise (CW) 4x4.5E propellers
• 2 x counter-clockwise (CCW) 4x4.5E propellers

What You Need

• A compatible multirotor or RC aircraft frame and motors sized for 4-inch props
• Appropriate prop adapters or collets to match your motor shaft diameter
• Tools to fit and balance the propellers if required
