8- to 10-inch FPV motor
iFlight NIDICI 3115
The 3115 of iFlight's NIDICI series, which iFlight sells at an economical price: 900KV or 1250KV for 6S, 77 g with wires, and up to 4.4 kg of pull per motor on a 10-inch tri-blade on iFlight's 24 V bench (900KV).
- 8- to 10-inch builds
- 6S
- 900KV on 9- to 10-inch props, 1250KV on 8- to 9-inch props
The spin is an illustration: the model turns at 1/600 of the no-load speed, and it is a generic 3115 motor drawn from iFlight’s published sizes, not its exact design. Thrust, current and power are iFlight’s bench figures for the HQ 10 × 4.5 × 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 10 × 4.5 × 3: 1,945 g of thrust, 17.5 A, 417 W, 4.66 g per watt.
On your quad
27.1 : 1
Thrust to weight at full throttle: four motors pull 17,624 g with the HQ 10 × 4.5 × 3 at 24 V.
At 60% throttle they pull 7,780 g, 12.0 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.

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, φ36.85 mm, with five spokes across the top that each fork in two toward the rim. (iFlight 900KV test report)
- Shaft. 5 mm, protruding 15.65 mm above the bell, with 10 mm of thread for the M5 flange nut. (iFlight 900KV test report)
- Magnets. Curved N52H magnets, 14 poles. (iFlight product page)
- Stator. 31 × 15 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 31 × 15 mm stator, 36.85 mm bell, 31.15 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.
