9x3N Narrow Propeller Details

This APC 9x3N narrow propeller is an RC-scale replacement blade intended for models that accept a narrow-hub 9x3 propeller. The part is made as a molded plastic blade designed to serve as a straightforward spare or tuning option for small electric model aircraft where a narrow hub is required.

Use this propeller as a direct swap when the hub type and bore match your model's mounting hardware. Before first run, confirm the propeller seats correctly on the hub, runs true without wobble, and is retained by the correct fastening method for your setup. Because hub and shaft interfaces vary across models, verify fitment rather than assuming universal compatibility.

In tuning and setup, a narrow-hub 9x3 propeller like this one is commonly used to adjust static thrust and motor load in small electric models. Check balance and blade integrity regularly, replace the propeller if you see cracks or deformation, and follow standard prop safety practices when handling and testing.
