1.8-inch cinewhoop motor
iFlight Defender 16 1002
The 2.7 g motor of the first Defender 16, iFlight's sub-250 g 1.8-inch cinewhoop: 14000KV on 2S, and 115 g of pull per motor on the Defender 16's tri-blade on iFlight's 8 V bench.
- 1.8-inch cinewhoops, such as iFlight's Defender 16 built before March 2024
- 2S
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 Defender 16 1809-3 prop at 8 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 Defender 16 1809-3: 68 g of thrust, 2.9 A, 23 W, 3.00 g per watt.
On your quad
0.7 : 1
Thrust to weight at full throttle: four motors pull 460 g with the Defender 16 1809-3 at 8 V.
At 60% throttle they pull 272 g, 0.4 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 you get for $13.99
Made for the Defender 16
iFlight designed it for ultralight sub-250 g builds on its Defender 16 frame with a whoop-style AIO board.

Replaced by a 1103
On 5 March 2024 iFlight moved the Defender 16 from this 1002 to a 1103 14000KV motor and still sells both. iFlight says the two need different configuration dumps, so don't mix them on one quad.

On a 10 × 2 mm stator with a φ12.5 mm bell.
Plug-in leads
50 mm, 28 AWG leads ending in an SH1.25 3-pin plug.

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 6.87 A, the peak iFlight measured at full throttle on the Defender 16 tri-blade at about 8 V. (iFlight 1002 test report)
- Props
- iFlight tested it with the Defender 16 1809-3, a 1.8-inch tri-blade with a 0.9-inch pitch: 48 g at half throttle and 115 g at full. (iFlight 1002 test report, iFlight Defender 16 prop page)
- Battery
- 2S; iFlight gives 8 V as the input, and the battery it sells for the Defender 16 is a 2S 900 mAh pack. (iFlight product page, iFlight Defender 16 battery page)
- Frame
- Three M1.4 holes on a 6.6 mm circle, the Defender 16 frame's motor mount. Four M1.4×3 screws come in the box. (iFlight product page, iFlight 1002 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 1002 test report)
- Shaft. 1.5 mm, protruding 3.25 mm above the bell; its end also stands out below the base. (iFlight 1002 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 1002 test report)
- Bearings. NMB, 4 × 1.5 × 2 mm. (iFlight 1002 test report)
- Base. 1 mm thick, with three M1.4 holes on a 6.6 mm circle. (iFlight 1002 test report)
How fast it spins
KV is the motor’s no-load speed per volt. With nothing on the shaft, the 14000KV 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 | 207,200 | 20,720 Hz | 124,320 |
| 4S full | 16.8 | 235,200 | 23,520 Hz | 141,120 |
| 6S nominal | 22.2 | 310,800 | 31,080 Hz | 186,480 |
| 6S full | 25.2 | 352,800 | 35,280 Hz | 211,680 |
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.
