6- to 7-inch FPV motor
VCI 2808
A 72.4 g 6S motor for 6- and 7-inch props; on VCI’s 24 V bench the 1350KV pulls 2,457 g at full throttle on a GF 7037-3.
- 6- and 7-inch quads
- 6S
- Gemfan 7037, 7040, 6032 and 6040 tri-blades (VCI’s test props)
The spin is an illustration: the model turns at 1/600 of the no-load speed, and it is a generic 2808 motor drawn from VCI’s published sizes, not its exact design. Thrust, current and power are VCI’s bench figures for the GF 7037-3 prop at 24 V, read straight across between its throttle steps. Its data starts at 30% 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 GF 7037-3: 1,028 g of thrust, 12.0 A, 288 W, 3.58 g per watt.
On your quad
15.1 : 1
Thrust to weight at full throttle: four motors pull 9,828 g with the GF 7037-3 at 24 V.
At 60% throttle they pull 4,112 g, 6.3 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 $15.70
About 2.4–2.65 kg on 6S
On VCI’s 24 V bench the 1350KV pulled 2,389 g on a GF 7040-3 and 2,457 g on a GF 7037-3, both at 46.24 A; the 1550KV pulled 2,650 g on a GF 7037-3 at 53.07 A.

What to pair it with
Our reading of VCI’s numbers, so your build matches what the motor was tested with.
- ESC
- VCI gives a peak current of 46.24 A for the 1350KV; for the 1550KV it gives 44.48 A, but its GF 7037-3 run reached 53.07 A at 24 V. Pick an ESC rated above that per motor. (VCI spec sheet)

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. N52SH 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 1350KV 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 | 19,980 | 2,331 Hz | 13,986 |
| 4S full | 16.8 | 22,680 | 2,646 Hz | 15,876 |
| 6S nominal | 22.2 | 29,970 | 3,497 Hz | 20,979 |
| 6S full | 25.2 | 34,020 | 3,969 Hz | 23,814 |
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 VCI’s published sizes: the 28 × 8 mm stator, 37 mm bell, 26.3 mm height, 5 mm shaft, 19 mm mounting circle and 12 teeth and 14 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.
