1S tiny whoop motor
iFlight XING 1002
A 2.4 g motor for 1S tiny whoops: 19000KV or 22000KV, NSK bearings, and 53 g (19000KV) or 70 g (22000KV) of pull per motor on a 40 mm tri-blade on iFlight's 1S bench.

- 40 mm tri-blade props
The spin is an illustration: the model turns at 1/600 of the no-load speed, and it is a generic 1002 motor drawn from iFlight’s published sizes, not its exact design. Thrust, current and power are iFlight’s bench figures for the HQ 40 mm prop at 4 V, read straight across between its throttle steps. Its data starts at 50% throttle.

- 53 g
- HQ 40 mm prop, 4 V
- Weight

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 40 mm: 34 g of thrust, 2.5 A, 10 W, 3.33 g per watt.
On your quad
0.3 : 1
Thrust to weight at full throttle: four motors pull 212 g with the HQ 40 mm at 4 V.
At 60% throttle they pull 136 g, 0.2 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 $13.99
2.4 g with wires
On a 10 × 2 mm stator with a φ12.5 mm bell.
Two KVs
19000KV and 22000KV. On a 40 mm tri-blade the 22000KV pulled 70 g at full throttle, against 53 g for the 19000KV.

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 the peak iFlight measured at full throttle on a 40 mm tri-blade on 1S: 5.3 A for the 19000KV and 7.8 A for the 22000KV. (iFlight 19000KV test report, iFlight 22000KV test report)
- Props
- iFlight tested both KVs with an HQ 40 mm tri-blade: 25 g and 29 g at half throttle, 53 g and 70 g at full (19000KV and 22000KV). (iFlight 19000KV test report, iFlight 22000KV test report)
- Battery
- 1S; iFlight gives 4 V as the input, and its bench runs fall from about 4.1 V at half throttle to 3.6 V at full. (iFlight product page, iFlight 19000KV test report, iFlight 22000KV test report)
- Frame
- Three M1.4 holes on a 6.6 mm circle. Four M1.4×4 screws come in the box. (iFlight product page, iFlight 19000KV 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, φ12.5 mm and 5.15 mm tall at the side, with four arms across the top. (iFlight 19000KV test report)
- Shaft. 1.5 mm, protruding 3.25 mm above the bell; its end also stands out below the base. (iFlight 19000KV test report)
- Magnets. Curved N52H magnets, 12 poles. (iFlight product page)
- Stator. 10 × 2 mm with 9 teeth, wound with single-strand copper; 28 AWG leads, 50 mm long, with an SH1.25 plug. (iFlight product page)
- Bearings. NSK, 4 × 2 × 1.5 mm as iFlight lists them. (iFlight product page)
- Base. 1 mm thick, with three M1.4 holes on a 6.6 mm circle. (iFlight 19000KV test report)
How fast it spins
KV is the motor’s no-load speed per volt. With nothing on the shaft, the 19000KV 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 | 281,200 | 28,120 Hz | 168,720 |
| 4S full | 16.8 | 319,200 | 31,920 Hz | 191,520 |
| 6S nominal | 22.2 | 421,800 | 42,180 Hz | 253,080 |
| 6S full | 25.2 | 478,800 | 47,880 Hz | 287,280 |
A 12-pole rotor has 6 pole pairs, so every turn of the shaft is 6 electrical cycles, and a six-step ESC switches the phases 36 times per turn.
About the 3D model
A generic outrunner drawn from iFlight’s published sizes: the 10 × 2 mm stator, 12.5 mm bell, 1.5 mm shaft, 6.6 mm mounting circle and 9 teeth and 12 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.
