2-inch cinewhoop motor
iFlight Defender 20 1204
The 5.8 g motor iFlight made for its sub-250 g Defender 20 cinewhoop: 6200KV on 3S, NMB bearings, and 177 g of pull per motor on the Defender 20's 2-inch tri-blade on iFlight's 12 V bench.

The spin is an illustration: the model turns at 1/600 of the no-load speed, and it is a generic 1204 motor drawn from iFlight’s published sizes, not its exact design. Thrust, current and power are iFlight’s bench figures for the Defender 20 2020-3 prop at 12 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 20 2020-3: 98 g of thrust, 2.9 A, 35 W, 2.81 g per watt.
On your quad
1.1 : 1
Thrust to weight at full throttle: four motors pull 708 g with the Defender 20 2020-3 at 12 V.
At 60% throttle they pull 392 g, 0.6 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 7.85 A, the peak iFlight measured at full throttle on the Defender 20's 2-inch tri-blade at about 12 V. (iFlight 6200KV test report)
- Props
- iFlight tested it with the Defender 20 2020-3 tri-blade: 73 g at half throttle and 177 g at full. The Defender 20 frame's guards are built for 2-inch props. (iFlight 6200KV test report, iFlight Defender 20 frame page)
- Battery
- 3S; iFlight gives 12 V as the input, and the battery it sells for the Defender 20 is a 3S 900 mAh pack. (iFlight product page, iFlight Defender 20 battery page)
- Frame
- Three M2 holes on a 9 mm circle, the Defender 20 frame's motor mount. Four M2×4 screws come in the box. (iFlight product page, iFlight 6200KV test report, iFlight Defender 20 frame page)

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, φ15.3 mm and 7.5 mm tall at the side, with four arms across the top and a direction arrow. (iFlight 6200KV test report)
- Shaft. 1.5 mm, protruding 3 mm above the bell; its end also stands out below the base. (iFlight 6200KV test report)
- Magnets. Curved N52H magnets, 12 poles. (iFlight product page)
- Stator. 12 × 4 mm with 9 teeth, wound with single-strand copper; 28 AWG leads, 60 mm long, with an SH1.25 plug. (iFlight 6200KV test report)
- Bearings. NMB, 5 × 2 × 2.5 mm. (iFlight 6200KV test report)
- Base. 1.5 mm thick, with three M2 holes on a 9 mm circle. (iFlight 6200KV test report)
How fast it spins
KV is the motor’s no-load speed per volt. With nothing on the shaft, the 6200KV 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 | 91,760 | 9,176 Hz | 55,056 |
| 4S full | 16.8 | 104,160 | 10,416 Hz | 62,496 |
| 6S nominal | 22.2 | 137,640 | 13,764 Hz | 82,584 |
| 6S full | 25.2 | 156,240 | 15,624 Hz | 93,744 |
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 12 × 4 mm stator, 15.3 mm bell, 11.2 mm height, 1.5 mm shaft, 9 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.
