5-inch FPV freestyle motor
Axisflying AE2306.5 V2
Axisflying's budget 5-inch motor on a 2306.5 stator, $15.90: 33.7 g, and 1685 g of thrust at full throttle on a BB4943.5 prop on Axisflying's 6S bench (1960KV).

The spin is an illustration: the model turns at 1/600 of the no-load speed, and it is a generic 2306.5 motor drawn from Axisflying’s published sizes, not its exact design. Thrust, current and power are Axisflying’s bench figures for the BB4943.5 prop at 23.98 V, read straight across between its throttle steps. Its data starts at 30% throttle.

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 BB4943.5: 795 g of thrust, 13.7 A, 327 W, 2.43 g per watt.
On your quad
10.4 : 1
Thrust to weight at full throttle: four motors pull 6,740 g with the BB4943.5 at 23.98 V.
At 60% throttle they pull 3,180 g, 4.9 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.

Ribbed top
Axisflying says the new ribs on the top improve impact resistance, and the motor is lower than the first version.

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 gunmetal ribbed top that Axisflying says improves impact resistance. (Axisflying feature images)
- Shaft. 5 mm with an M5 thread, standing 13.8 mm above the bell; an M3×4 screw locks it. (Axisflying drawing and specs)
- Bearings. NMB bearings. (Axisflying feature images)
- Stator. 23 × 6.5 mm, 12 slots, with 14 magnet poles in the bell. (Axisflying drawing and specs)
- Leads. 20 AWG silicone wire, 150 mm. (Axisflying drawing and specs)
How fast it spins
KV is the motor’s no-load speed per volt. With nothing on the shaft, the 1960KV 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 | 29,008 | 3,384 Hz | 20,306 |
| 4S full | 16.8 | 32,928 | 3,842 Hz | 23,050 |
| 6S nominal | 22.2 | 43,512 | 5,076 Hz | 30,458 |
| 6S full | 25.2 | 49,392 | 5,762 Hz | 34,574 |
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 23 × 6.5 mm stator, 27.9 mm bell, 18.9 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.
