Electric Multi-Rotor 8x4.5 Replacement Propeller - APC AP08045MR  [AP08045MR]

8x4.5 Electric multirotor propeller

This APC AP08045MR propeller is an RC-scale replacement blade designed for electric multi-rotor models. It is intended as a direct spare for standard 8x4.5 applications and will influence thrust and control response during tuning and normal use.

Keep the installation simple and safe: ensure the propeller's orientation matches the motor rotation, mount it on the correct threaded adapter, and verify there is adequate clearance from the airframe. Mount on a flat, balanced surface and inspect for any nicks or cracks before flying to reduce vibration transfer to the frame and electronics.

• Compatibility focus: Suited to electric multi-rotor platforms that accept 8x4.5 props and best treated as a size-matched replacement rather than a performance upgrade.
• Installation tips: Confirm rotation direction, secure the prop to the hub to the recommended torque, and recheck fasteners after a short test hover.
• Tuning role: Blade pitch and diameter affect hover stability and throttle response; record flight behaviour before and after swapping props.
