Axisflying AE2505

What it pulls

Axisflying’s own bench test, one line per prop. Drag across the chart to move the throttle; the model above follows.

What you get for $19.90

• Two KVs, two styles

  Axisflying pitches the 1750KV for smooth, cinematic flow flying and the 2050KV for aggressive sbang flying.

• Larger stator

  Axisflying says the 25 × 5 mm stator gives more torque, and that the magnetic design holds off desyncs at low rpm.

• Bench numbers

  On a 51466 V2 at about 23 V: 1232.07 g at 35.68 A (1750KV) and 1421.71 g at 47.66 A (2050KV), with 64.8 °C and 79.7 °C measured inside the motor at 35.5 °C ambient.

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 32.3 A (1750KV, HQ MCK) to 47.66 A (2050KV, 51466 V2). (Axisflying 1750KV test data, Axisflying 2050KV test data)

Props

Axisflying recommends 51466 V2, HQ 6×3×3, HQ MCK and 51366 props and tested on them; the 51466 V2 pulled the most on both KVs. (Axisflying product page, Axisflying 1750KV test data, Axisflying 2050KV test data)

Battery

6S. (Axisflying product page, Axisflying drawing and specs)

Frame

Four M3 screws on a 16 mm circle. (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. Gunmetal anodised, with forked spokes on the top and polished cut edges. (Axisflying product photo)
• Shaft. 5 mm with an M5 thread, 10 mm of it threaded. (Axisflying drawing and specs)
• Stator. 25 × 5 mm, 12 slots, with 14 magnet poles in the bell. (Axisflying product page)
• Leads. 20 AWG silicone wire, 155 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 1750KV 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 25 × 5 mm stator, 30.5 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.
