Reversible 8x4.5MR Multirotor Propeller - APC AP08045MRP  [AP08045MRP]

Summary of the 8x4.5MR propeller

The APC 8x4.5MR is an RC propeller made for electric multirotor models where both pusher and normal mounting are useful. The 8x4.5 label indicates diameter and pitch relevant to hobby pilots, and the reversible capability allows the blade to be used in either orientation to produce thrust in the required direction.

Installation notes recommend fitting the prop to the correct hub, confirming motor rotation, and securing the fasteners to prevent slipping. Verify compatibility of the mounting interface before the first use and inspect the blade for any defects prior to each flight to reduce risk.

When tuning, balance the prop to remove vibration, check thrust direction after installation, and make measured ESC and motor adjustments to refine performance. This propeller provides a straightforward way to influence thrust and efficiency on small electric multirotor platforms.
