APC AP1404W 14x4W Wide Blade Propeller - 3D Fun Fly  [AP1404W]

Overview of the APC AP1404W Wide-Blade Propeller

The APC AP1404W is a 14x4W wide-blade propeller intended for electric RC aircraft and 3D fun fly use. Below is a technical, application-focused description covering functional behaviour in an RC setup, installation pointers, and how the prop affects tuning.

Compatibility relies on diameter, pitch and hub fit rather than brand, so confirm your spinner and motor shaft accept the 14x4W hub pattern before buying. It will serve as a like-for-like replacement when the original prop matches the 14x4W specification.

Installation notes: check the hub and bore for any wear, seat the prop firmly against the spinner or adapter, and secure with the appropriate nut or prop saver for your shaft. Turn the motor by hand to ensure there is no contact and the prop spins true.

Tuning impact: a wide-blade shifts thrust characteristics versus narrower blades, often improving low-speed lift and response useful for 3D manoeuvres and slow hovers. Be prepared to tweak trims and throttle curves, and re-check motor current and ESC thermal behaviour after a prop change.

Pre-flight safety: balance the prop before mounting, verify correct rotation, and perform a restrained ground run to confirm absence of excessive vibration or abnormal motor load.
