The APC AP04535 propeller is specified as a replacement for 1/2A pylon and combat class model aircraft and is listed by its 4.5x3.5 size. It functions as a direct spare or a tuning blade for lightweight electric models used in close-course flying.
Choose this prop when the 4.5x3.5 dimension suits your setup; swapping it will adjust thrust and rpm characteristics to help refine handling. Prior to flight, always check that the hub fit and spinner clearance on your model are correct to prevent interference.
Offered as a single propeller unit, this accessory is aimed at hobbyists and competitors tuning 1/2A models; no extra adapters or hardware are included in the package.
