5-inch FPV freestyle motor
Axisflying Modular AF2406
Axisflying's modular 5-inch motor: the body comes off a separate base, which Axisflying says makes a motor swap a 15-second, solder-free job; 1826 g (1860KV) or 1929 g (2080KV) at full throttle on a 51466 V2 on 6S.
- 5-inch freestyle and bando (2080KV)
- 5-inch cinematic builds carrying a GoPro (1860KV)
- 4S–6S
The spin is an illustration: the model turns at 1/600 of the no-load speed, and it is a generic 2406 motor drawn from Axisflying’s published sizes, not its exact design. Thrust, current and power are Axisflying’s bench figures for the 51466 V2 prop at 23.97 V, read straight across between its throttle steps. Its data starts at 30% throttle.

- Weight

What it pulls
Axisflying’s own bench test, one line per prop. Drag across the chart to move the throttle; the model above follows.
At 60% with the 51466 V2: 924 g of thrust, 14.1 A, 337 W, 2.70 g per watt.
On your quad
11.2 : 1
Thrust to weight at full throttle: four motors pull 7,304 g with the 51466 V2 at 23.97 V.
At 60% throttle they pull 3,696 g, 5.7 times the quad’s weight.
All-up weight is the quad ready to fly, with its battery and camera. The thrust is the maker’s static bench figure; in the air it is lower.
What you get for $28.90
Swap without soldering
The motor body and its base are separate parts: loosen the mounting screws, change the motor and tighten them again. Axisflying puts the swap at 15 seconds.

Plated contacts
Current passes through gold-plated upper and lower PCBs and nickel-plated copper shims, pressed together by a steel wave spring Axisflying rates for over 200 °C; the PCB is rated for 60 A.
Tested for swapping
Axisflying says the design passed 500 rounds of assembly and disassembly and 100 water-immersion tests, plus long heavy-load and static runs.

Bench numbers
On a 51466 V2 at about 23.5 V: 1826 g at 40.95 A (1860KV) and 1929 g at 47.44 A (2080KV), with 44 °C and 40 °C measured inside the motor.

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 a dark bronze spoked top and a red ring round its edge. (Axisflying product photo)
- Base. A separate base holds the contacts: upper and lower PCBs, gold-plated, with nickel-plated copper shims and a wave spring. An optional 7075 aluminium cap, 23.2 × 16.8 × 3 mm and 2.1 g, closes it. (Axisflying base specs, Axisflying structure image)
- Shaft. 5 mm with an M5×0.8 thread, 9 mm of it usable, standing 13.4 mm above the bell. (Axisflying drawing)
- Stator. 24 × 6 mm, 12 slots, with 14 magnet poles in the bell. (Axisflying product page, Axisflying spec tables)
- Leads. 20 AWG silicone wire, 150 mm. (Axisflying spec tables)
How fast it spins
KV is the motor’s no-load speed per volt. With nothing on the shaft, the 1860KV 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.
| Battery | Volts | No-load rpm (KV × V) | Electrical frequency | ESC steps per second |
|---|---|---|---|---|
| 4S nominal | 14.8 | 27,528 | 3,212 Hz | 19,270 |
| 4S full | 16.8 | 31,248 | 3,646 Hz | 21,874 |
| 6S nominal | 22.2 | 41,292 | 4,817 Hz | 28,904 |
| 6S full | 25.2 | 46,872 | 5,468 Hz | 32,810 |
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, 29.5 mm bell, 19.55 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.
