5-inch FPV motor
VCI PRO 2207
A 6S 5-inch motor; on VCI’s 24 V bench the 1950KV pulled 1,718 to 1,907 g per motor at full throttle, depending on the prop.
- 5-inch quads
- 6S
- Tri-blades such as the GF 51466 or HQ 5.1 × 3.8
The spin is an illustration: the model turns at 1/600 of the no-load speed, and it is a generic 2207 motor drawn from VCI’s published sizes, not its exact design. Thrust, current and power are VCI’s bench figures for the GF F4-3B 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 F4-3B: 625 g of thrust, 9.5 A, 227 W, 2.75 g per watt.
On your quad
11.7 : 1
Thrust to weight at full throttle: four motors pull 7,628 g with the GF F4-3B at 24 V.
At 60% throttle they pull 2,500 g, 3.8 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 $22.00
About 1.9 kg on 6S
On VCI’s 24 V bench the 1950KV pulled 1,907 g at full throttle on a GF F4-3B, drawing 42.99 A.

What to pair it with
Our reading of VCI’s numbers, so your build matches what the motor was tested with.
- ESC
- VCI’s peak currents are 44.73 A (1950KV), 47.37 A (2050KV) and 50.27 A (2100KV), each on the GF 51466-3B at 24 V; pick an ESC rated above that per motor. (VCI spec sheet)
- Props
- VCI tested four tri-blades at 24 V: GF F3, GF F4, GF 51466 and HQ 5.1 × 3.8. The 1950KV made 1,718 to 1,907 g at full throttle, most on the GF F4. (VCI spec sheet)
- Battery
- 6S; VCI rates every KV for 6S (24 V). (VCI spec sheet)
- Frame
- Four M3 holes on a 16 × 16 mm pattern. (VCI drawing)

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 1950KV 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 | 28,860 | 3,367 Hz | 20,202 |
| 4S full | 16.8 | 32,760 | 3,822 Hz | 22,932 |
| 6S nominal | 22.2 | 43,290 | 5,051 Hz | 30,303 |
| 6S full | 25.2 | 49,140 | 5,733 Hz | 34,398 |
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 22 × 7 mm stator, 27 mm bell, 19.2 mm height, 5 mm shaft, 16 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.
