What you get for $23.90

• Built with cinematic pilots

  Axisflying says it designed its C series with cinematic pilots Antoine DG (Escape FPV) and Fry, aiming for smooth, responsive throttle and long flight times.

What to pair it with

Our reading of Axisflying’s numbers, so your build matches what the motor was tested with.

ESC

Full-throttle currents on Axisflying's 6S bench run from 39.04 A (1850KV, BB 4943.5) to 46.57 A (2050KV, GF 51466); the page text says about 45 A. (Axisflying product page, Axisflying 1650KV test data, Axisflying 1850KV test data, Axisflying 2050KV test data)

Props

6-inch props for the 1650KV (tested on an HQ 6x3.5); 5-inch for the 1850KV and 2050KV, tested on BB 4943.5, HQ J37 and GF 51466 props. (Axisflying product page, Axisflying 1650KV test data, Axisflying 1850KV test data, Axisflying 2050KV test data)

Battery

6S for the 1650KV, 1850KV and 2050KV; Axisflying tested the 2650KV, and the 1850KV once more, on 4S. (Axisflying product page, Axisflying 1850KV test data, Axisflying 2650KV test data)

Frame

Four M3 screws on a 16 mm circle; four M3×8 screws come in the box. (Axisflying product page, Axisflying drawing and specs)

Bench data

Redrawn from Axisflying’s test reports. Thrust is static pull on a bench, more than you get in flight. Power is volts × amps; efficiency is thrust divided by power.

Inside the motor

A brushless outrunner: the coils stand still in the middle and the magnets spin around them. From the top down:

• Bell. Black, with eight black spokes on the top, red ribs below them, and a knurled hub. (Axisflying product photo, Axisflying top-view photo)
• Shaft. 5 mm with an M5 thread, 9 mm of it threaded, standing 13.8 mm above the bell. (Axisflying drawing and specs)
• Bearings. Housed behind Axisflying's IP53 bearing shield. (Axisflying product page)
• Stator. 24 × 6 mm, 12 slots, with 14 N52H arc magnets in the bell. (Axisflying product page)
• Leads. 20 AWG silicone wire, 150 mm. (Axisflying product page, Axisflying drawing and specs)

How fast it spins

KV is the motor’s no-load speed per volt. With nothing on the shaft, the 1850KV version reaches about these speeds; a prop loads the motor and brings it down, typically to around 70–75% of these figures at full throttle.

A 14-pole rotor has 7 pole pairs, so every turn of the shaft is 7 electrical cycles, and a six-step ESC switches the phases 42 times per turn.

About the 3D model

A generic outrunner drawn from Axisflying’s published sizes: the 24 × 6 mm stator, 29.3 mm bell, 18 mm height, 5 mm shaft, 16 mm mounting circle and 12 teeth and 14 magnets. Anything Axisflying doesn’t publish is typical for a motor this size, and the bell’s spoked top, the base and the inside are a generic design, not this motor’s. The colours are read off the maker’s product photos. There are no logos or markings: it is our drawing, not the maker’s.
