APC AP1712W 17 x 12W Wide Blade Prop - 140 Pattern  [AP1712W]

Product Brief: APC AP1712W

The APC AP1712W is an RC-scale 17x12W propeller built with a wide 140 blade section to improve low-speed thrust and punch for fixed-wing aircraft. The 17x12W label describes diameter and pitch combined with a wider blade form, which changes the propulsive load compared with narrower blades.

Fit this prop as a spare or during prop tests to refine climb performance, throttle response, and slow-speed control. Treat it as an aftermarket accessory and select props based on motor KV, ESC capacity, and airframe loading rather than assuming interchangeable fitment across different designs.

Installation tips: examine the hub bore and mating faces for burrs, ensure the prop seats squarely on your adapter or spinner backplate, and tighten the retaining nut to the motor manufacturer's torque spec while checking for axial and radial runout. Static and dynamic balancing prior to first flight is advised to reduce vibration through the motor and airframe.

Tuning notes: the wide 140 pattern typically boosts thrust at lower RPMs but increases current draw relative to smaller-pitch or narrow-blade options. Watch motor and ESC temps during run-ups and move to a different pitch or blade profile if overheating or heavy vibration is seen.
