APC AP0947SFP Propeller 9x4.7SFP Electric Slow Flyer Reverse/Pusher  [AP0947SFP]

Electric slow-flyer reverse/pusher propeller

This APC AP0947SFP propeller is an RC-scale accessory intended for electric slow-flyer setups that require a reverse or pusher orientation. The product name contains its basic dimensions so use that as a reference when matching to your airframe and motor installation.

Practical notes for hobbyists:

• Compatibility: Use this propeller where the model designation calls for a 9x4.7 size and a reverse or pusher mounting; confirm spinner, hub, and shaft fit before final installation.
• Pre-install checks: Inspect the prop for visible defects, verify the mounting hole alignment, and perform static balance with a prop balancer to reduce vibration at low RPM.
• Installation tips: Mount with correct face orientation for pusher versus tractor use, tighten retaining hardware evenly, and re-check balance after securing the prop.
• Tuning role: On slow flyers a 9x4.7 propeller affects static thrust and low-end efficiency; pairing the prop with appropriate motor timing and ESC settings helps achieve smooth low-RPM performance.
• Safety: Keep hands clear of the prop when powering the model, and bench-test at low throttle to confirm secure fitment and acceptable vibration levels.
