APC AP16513W 16.5x13W Wide Blade Propeller Spare for RC Models  [AP16513W]

Large-width propeller for performance tuning

The APC AP16513W is supplied as a 16.5x13W wide-blade propeller and is catalogued with the 120 pattern identifier. The increased blade width modifies the airflow and loading relative to narrow-blade options, and can be applied to adjust climb characteristics and throttle response on electric aircraft. This description highlights fitment guidance, basic setup checks, and the blade's effects on trimming and balance during flight testing.

Compatibility covers RC electric aircraft and park-style models that accept the 16.5x13W mounting pattern; verify hub diameter and spinner clearance before fitting. Follow standard prop replacement practice: inspect the hub and motor shaft for damage, make sure the prop seats flush on the adapter or motor face, and fasten using the correct nut and washer order recommended by your model. Match the rotation marking on the prop to the motor's rotation direction.

Static balancing and careful trimming are key to achieving predictable results with a wide blade. Balance the prop before first operation, then conduct a low-throttle ground vibration test. If vibration continues, re-check seating and spinner fitment and address the root cause rather than relying on aggressive trim. The wider blade often produces greater low-to-mid throttle thrust, so adjust throttle programming and check motor temperatures during early flights.

When trialling alternative props, log RPM and flight behaviour rather than depending on impressions; a structured swap-and-test routine yields reliable tuning information. Employ the AP16513W in a stepwise setup process to refine climb performance, cruise efficiency, and handling balance for your particular airframe and power system.
