APC AP1104 11x4 Performance RC Propeller  [AP1104]

Tuning and performance notes for 11x4 blades

The APC AP1104 propeller is supplied as a hobby replacement blade for electric model aircraft and trainers. This overview highlights how the 11x4 size influences handling and tuning choices, helping pilots choose the right blade for desired thrust and RPM behavior.

Mounting is generally quick on most spinner and hub arrangements: check spinner bore and adaptor fit, install the prop with the correct nut or backplate, and follow torque recommendations for your spinner hardware. For collet or threaded shaft systems, confirm the prop is seated and centered prior to final tightening to avoid imbalance.

From a performance viewpoint, the 11x4 label specifies diameter and pitch, which affect acceleration, top speed, and motor load. Use a prop balancer and monitor motor current and RPM under load to fine-tune your setup and avoid overstressing the power system.
