APC AP09045EP PROPELLER 9x4.5EP ELECTRIC REVERSE/PUSHER  [AP09045EP]

Electric reverse/pusher propeller

This APC AP09045EP 9x4.5EP propeller is an RC-scale replacement blade intended for electric pusher or reverse-thrust arrangements. It is supplied as a single-purpose propeller designed to serve as a spare or hop-up for small electric models that use pusher or rear-mounted motor layouts.

Installation and fitment focus on common RC practice: confirm shaft diameter and prop adapter compatibility before mounting, balance the propeller on a hobby balancer, and secure using the correct nut or collet for your motor shaft. Ensure rotation direction matches the intended thrust side and perform a static run check at low throttle to verify clearance and vibration.

Tuning role and maintenance: this prop acts as a direct way to alter thrust, cruise rpm, and noise characteristics without changing the motor or ESC. Regularly inspect for nicks or cracks, rebalance after any repair, and replace the prop if structural damage is found to avoid undue strain on the motor bearings.

• Compatibility note: Intended for electric RC models with pusher/reverse layouts rather than specifying chassis or exact models.
• Installation tips: Balance before use, hand-tighten then torque to recommended hardware feel, re-check after first flight.
• Tuning advice: Swap to coarser or finer pitch props to adjust static thrust and cruise RPM while monitoring motor temperature.
