The APC AP04535 propeller is specified as a replacement for 1/2A pylon and combat model aircraft. It is listed by size, 4.5x3.5, and intended as an economical spare or tuning blade for compact electric models used in tight-course flying.
Select this prop when the 4.5x3.5 size aligns with your setup goals; swapping it in will change thrust and rpm balance to help refine handling. Before flying, verify hub fit and spinner clearance on your model to prevent rubbing or contact.
Sold as a single propeller, this accessory suits hobbyists and competitors needing a straightforward option for performance trials at the 1/2A scale. No additional adapters or mounting hardware are included.
