The spin is an illustration: the model turns at 1/600 of the no-load speed, and it is a generic 0702 motor drawn from VCI’s published sizes, not its exact design. Thrust, current and power are VCI’s bench figures for the GF1219S-3 prop at 4 V, read straight across between its throttle steps. Its data starts at 10% throttle.

What it pulls
VCI’s own bench test, one line per prop. Drag across the chart to move the throttle; the model above follows.
At 60% with the GF1219S-3: 18 g of thrust, 2.9 A, 11 W, 1.58 g per watt.
On your quad
0.2 : 1
Thrust to weight at full throttle: four motors pull 140 g with the GF1219S-3 at 4 V.
At 60% throttle they pull 72 g, 0.1 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 $35.00
35 g at full throttle
On VCI’s 4 V bench the 27000KV pulled 35 g on a GF1219S-3 at 5.15 A; the 30000KV pulled 37.1 g at 5.9 A and the 23000KV 32 g at 3.9 A.

1.4 g
VCI gives 1.4 g with the cable for the 23000KV and 27000KV, and 1.38 g for the 30000KV.

Bench data
Redrawn from VCI’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:
- Magnets. 52SH arc magnets. (VCI spec sheet)
How fast it spins
KV is the motor’s no-load speed per volt. With nothing on the shaft, the 27000KV 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 | 399,600 | 39,960 Hz | 239,760 |
| 4S full | 16.8 | 453,600 | 45,360 Hz | 272,160 |
| 6S nominal | 22.2 | 599,400 | 59,940 Hz | 359,640 |
| 6S full | 25.2 | 680,400 | 68,040 Hz | 408,240 |
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 VCI’s published sizes: the 7 × 2 mm stator, 9 mm bell, 8 mm height, 1 mm shaft, 6.6 mm mounting circle and 9 teeth and 12 magnets. Anything VCI 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.
