4.75x4 APC AP0474 RC Propeller — 1/2A Pylon/Combat Replacement  [AP0474]

Compact 4.75x4 prop for 1/2A pylon and combat models

The APC AP0474 propeller is offered as a replacement RC blade for 1/2A pylon and combat sport models. Manufactured from polycarbonate, it is aimed at small-scale sport pilots who often swap props and fine-tune setup. The copy focuses on compatibility, correct fitting, and how prop changes influence handling without asserting measurable performance claims.

Fit is governed by the hub bore and shaft diameter rather than the aircraft type alone. Confirm the prop hub matches your prop adapter or shaft; adapters and bushings are commonly used to adapt propellers to different shafts. Keep adequate clearance from the airframe and control surfaces to prevent contact during aggressive manoeuvres.

Mounting tips: ensure the blade pitch and rotation align with motor direction, hand-tighten the retaining nut or collet, then apply the adapter-specified torque. Balance the propeller statically after installation and check for any rubbing at maximum control deflection. Do a low-power test run to check vibration and retention before attempting full-throttle flights.

Tuning impact: fitting a 4.75x4 will change thrust and responsiveness compared to other diameter or pitch choices, so use prop swaps for incremental tuning—assess balance, observe motor load, and tweak power settings or prop selection to dial in handling for pylon or combat formats. The part is described solely as an RC accessory.
