APC AP1359 Propeller 13.5x9 (60 pattern) RC propeller  [AP1359]

APC AP1359 Propeller overview

This APC AP1359 13.5x9 propeller is an RC-scale replacement designed for use on electric and sport-scale RC aircraft where the 13.5x9 size and 60 pattern blade shape are required. The article focuses on fit, installation considerations, and the role the propeller plays in tuning thrust and handling rather than raw performance claims.

Compatibility is typically determined by hub diameter and prop adapter type on the model; confirm the prop fits your motor shaft and adapter before installation. The 60 pattern wording refers to blade geometry and affects airflow and loading characteristics relevant to trimming and mid-range thrust behaviour.

Installation notes: inspect the hub and blade for any manufacturing flash, balance the propeller on a static balancer before first run, and secure it with the correct nut or collet recommended by your motor or prop adapter manufacturer. Proper balance and correct rotation direction are essential to avoid undue vibration that can affect onboard electronics and airframe integrity.

Tuning role: swapping to this 13.5x9 propeller can change throttle feel and cruise RPM, so expect to revisit throttle curves on your ESC and check motor temperature during initial runs. Use incremental changes and log results to fine-tune thrust, climb rate, and handling balance.
