APC Props Multi Rotor 9x4.5 RC Propeller - APC09045MR

The APC Props 9x4.5 Multi Rotor propeller (APC09045MR) is a purpose-built drone and multi-rotor prop designed for smooth, efficient thrust in quadcopter and multi-rotor RC aircraft builds. At 9 inches in diameter with a 4.5-inch pitch, it strikes a practical balance between lift and efficiency, making it a popular choice for mid-size multi-rotor frames. APC is a well-regarded name in RC aircraft propellers, and this prop is precision-moulded to tight tolerances for consistent balance straight out of the packet — which matters when you're running multiple props in a multi-rotor configuration.

Key Features

• 9-inch diameter with 4.5-inch pitch, suited to mid-size multi-rotor and quadcopter frames
• Precision-moulded construction for consistent balance, reducing vibration in multi-rotor setups
• Designed specifically for multi-rotor applications, not repurposed from fixed-wing prop designs
• Compatible with standard prop adapters and collet-style mounts used on common brushless motor shafts
• Available as a single propeller — buy in pairs or sets of four to equip a full multi-rotor build

What's Included

• 1x APC 9x4.5 Multi Rotor propeller

What You Need

• Additional props to complete a multi-rotor build (typically sold in pairs for CW/CCW configuration)
• Compatible prop adapter or collet mount to suit your motor shaft diameter
• Counter-rotating (pusher) variant if your multi-rotor requires mixed prop directions
