This APC AP04535 propeller is offered as a replacement for 1/2A pylon and combat class model aircraft, identified by its 4.5x3.5 dimensions. It serves as a practical spare or a tuning option for small-displacement electric airframes used in close-course flying.
Fit this prop where the 4.5x3.5 size meets your performance needs; swapping the prop provides a direct way to alter thrust and rpm characteristics during setup. Confirm hub compatibility and spinner clearance on your model before final installation.
Presented as a single propeller item, this product is a budget-friendly accessory for hobbyists and competitors tuning 1/2A models. Adapters and extra hardware are not included with the unit.
