APC AP09045EP 9x4.5EP Electric Reverse/Pusher Propeller  [AP09045EP]

Reverse-thrust electric propeller

This APC AP09045EP 9x4.5EP propeller is an RC-scale replacement blade made for electric pusher and reverse-thrust arrangements. It is supplied as a single prop unit suitable as a spare or an upgrade for small electric models that use rear-mounted motors or pusher layouts.

Installation and fitment follow standard RC practice: confirm the prop bore matches your shaft adapter or collet, balance the prop on a hobby balancer, and secure it with the correct nut or collet for your motor shaft. Verify the rotation direction corresponds to the intended thrust side and perform a low-throttle static run to check clearance and vibration before full use.

Tuning and upkeep: this propeller changes static thrust, cruise RPM, and acoustic signature without swapping motors or ESCs. Inspect regularly for nicks or cracks, rebalance after any repair, and replace if structural damage is detected to protect motor bearings.

• Compatibility note: Intended for electric RC models with pusher/reverse layouts rather than listing specific chassis or model numbers.
• Installation tips: Balance before first use, hand-tighten then secure to the recommended feel, and re-check after the initial run.
• Tuning advice: Try coarser or finer pitch props to alter static thrust and cruise RPM while monitoring motor temperature and load.
