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

APC AP1712W Key Features

This APC AP1712W propeller is a scale-style replacement intended for fixed-wing RC aircraft where the wide 140 blade pattern provides greater low-speed thrust and improved climb performance. The 17x12W designation identifies diameter and pitch with a broad blade profile that modifies airflow and motor load compared with narrower options.

Use the prop as a direct spare or when experimenting with propeller selection to tune climb rate, throttle response, and handling at slow speeds. Always select a propeller to suit motor KV, ESC ratings, and airframe loading rather than assuming compatibility across different platforms.

Fitting advice: inspect the hub bore and mating surfaces for burrs or damage, ensure the prop sits flush on the adapter or spinner backplate, and tighten the retaining nut to the motor manufacturer's specified torque, checking for both axial and radial runout. Conduct static and dynamic balancing before the initial flight to reduce transmitted vibration.

Tuning comments: a wide 140 blade generally increases thrust at lower RPMs while raising current draw in comparison to smaller-pitch or narrow-blade choices. Monitor motor and ESC temperatures during setup flights and swap to a different pitch or blade style if you observe overheating or undue vibration.
