APC AP0463 4.6x3 Replacement Prop for 1/2A Pylon and Combat RC Models  [AP0463]

Compact 4.6x3 replacement prop for 1/2A airframes

This is an RC-scale 4.6x3 propeller listed as APC AP0463, produced as a spare or replacement for 1/2A pylon and combat type small electric models. The 4.6x3 marking denotes diameter and pitch and helps pilots match prop geometry to the intended handling and powerband of compact motors.

Compatibility is determined by the model's prop diameter clearance and hub/shaft fitment rather than by a specific airframe make; verify that your aircraft accepts a 4.6-inch diameter with a 3-inch pitch and that the hub profile matches your motor or adapter. Changing to a 4.6x3 affects RPM and thrust characteristics, so it should be chosen as a tuning option to shape acceleration and top speed.

Installation notes: inspect the prop for chips or cracks and confirm the rotation direction before fitting. Secure the prop to the motor shaft or spinner adapter with the correct nut or locking method, then check hub runout and static balance. A well balanced, correctly tightened prop reduces vibration and improves reliability for pylon or combat flying.

Tuning role: the 4.6x3 tends to offer moderate top speed with good midrange response, making it suitable for tight-course pylon work and close-quarters combat. After swapping props, monitor motor temperature and ESC load during initial throttle checks to ensure safe operation for your power system.
