8- to 9-inch FPV motor
iFlight NIDICI 2812
The 2812 of iFlight's NIDICI series, which iFlight sells at an economical price: 900KV for 6S, a 5 mm shaft, and 2.3 kg of pull on an 8-inch or 2.95 kg on a 9-inch tri-blade on iFlight's 24 V bench.
- 8- to 9-inch builds
- 6S
The spin is an illustration: the model turns at 1/600 of the no-load speed, and it is a generic 2812 motor drawn from iFlight’s published sizes, not its exact design. Thrust, current and power are iFlight’s bench figures for the HQ 9 × 4 × 3 prop at 24 V, read straight across between its throttle steps. Its data starts at 50% throttle.

What it pulls
iFlight’s own bench test, one line per prop. Drag across the chart to move the throttle; the model above follows.
At 60% with the HQ 9 × 4 × 3: 1,695 g of thrust, 17.2 A, 410 W, 4.14 g per watt.
On your quad
18.2 : 1
Thrust to weight at full throttle: four motors pull 11,804 g with the HQ 9 × 4 × 3 at 24 V.
At 60% throttle they pull 6,780 g, 10.4 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 to pair it with
Our reading of iFlight’s numbers, so your build matches what the motor was tested with.
- ESC
- Rated for at least 43.9 A, the peak iFlight measured at full throttle on an HQ 9 × 4 × 3 at about 24 V. A 50 A or bigger ESC leaves room to spare. (iFlight 900KV test report)
- Props
- iFlight tested it with an HQ 8 × 4 × 3 (2,298 g at full throttle, 59 °C) and an HQ 9 × 4 × 3 (2,951 g, 94 °C). (iFlight 900KV test report)
- Battery
- 6S; iFlight gives 24 V as the input. (iFlight product page)
- Frame
- Four M3 holes on a 19 mm circle (19 × 19). Four M3×10 screws and an M5 flange nut come in the box. (iFlight product page, iFlight 900KV test report)

Bench data
Redrawn from iFlight’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. Segmented, in iFlight's words, φ33.55 mm, with five spokes across the top that each fork in two toward the rim. (iFlight 900KV test report)
- Shaft. 5 mm, protruding 15.15 mm above the bell, with 9 mm of thread for the M5 flange nut. (iFlight 900KV test report)
- Magnets. Curved N52H magnets, 14 poles. (iFlight product page)
- Stator. 28 × 12 mm with 12 teeth, wound with single-strand copper; 18 AWG leads, 260 mm long. (iFlight product page)
- Bearings. 11 × 5 × 5 mm; iFlight doesn't name the maker. (iFlight 900KV test report)
- Base. 3.5 mm thick, with four M3 holes on a 19 mm circle. (iFlight 900KV test report)
How fast it spins
KV is the motor’s no-load speed per volt. With nothing on the shaft, the 900KV 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 | 13,320 | 1,554 Hz | 9,324 |
| 4S full | 16.8 | 15,120 | 1,764 Hz | 10,584 |
| 6S nominal | 22.2 | 19,980 | 2,331 Hz | 13,986 |
| 6S full | 25.2 | 22,680 | 2,646 Hz | 15,876 |
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 iFlight’s published sizes: the 28 × 12 mm stator, 33.55 mm bell, 27.65 mm height, 5 mm shaft, 19 mm mounting circle and 12 teeth and 14 magnets. Anything iFlight 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.
