APC AP1712W 17x12W Wide Blade Propeller (140 Pattern)  [AP1712W]

APC 17x12W Propeller Overview

This APC AP1712W propeller is a replacement prop designed for fixed-wing RC models that benefit from the 140 wide-blade profile to boost low-speed thrust and climb punch. The 17x12W marking denotes the diameter and pitch combined with a wide blade cross section, which alters airflow and motor loading versus narrower props.

Fit this prop as a spare or while testing different props to refine climb rate, throttle response, and slow-speed handling. Treat the item as an aftermarket accessory and match prop choice to motor KV, ESC capacity, and airframe loading rather than assuming universal fitment.

Installation guidance: check the hub bore and mating surfaces for burrs, ensure the prop seats squarely on the adapter or spinner backplate, and tighten the retaining nut to the motor maker's recommended torque while inspecting axial and radial runout. Perform static and dynamic balancing before first flight to reduce vibration transmitted to the motor and airframe.

Tuning notes: the wide-blade 140 geometry typically raises low-RPM thrust but also increases current draw compared with smaller-pitch or narrow-blade options. Monitor motor and ESC temperature during testing and change pitch or blade profile if you see excessive heat or vibration.
