APC AP1606 Propeller 16x6 Spare for Electric Model Aircraft  [AP1606]

Prop characteristics and application

This APC AP1606 is an aftermarket replacement propeller for electric prop-driven model aircraft and compatible RC configurations. It is designed as a spare for maintenance, repairs, and tuning sessions where diameter and pitch selection affect thrust and motor loading. It should be used only as an accessory on electric models.

Installation requires correct hub engagement and firm fastening to the motor or prop adapter. Confirm the prop bore matches the shaft or collet, fit any necessary adapter, and ensure the prop sits true before tightening to avoid vibration. A static balance is advised after mounting and before flying.

For tuning, align prop diameter and pitch with motor and ESC capabilities, monitor RPM and motor temperature under operational load, and adjust prop size or gearing if the system draws too much current. Exchanging props like this one is an effective method to evaluate pitch changes during trimming.
