Drawing the 3D model…

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)
Props
VCI tested the 1350KV on 7-inch GF 7040-3 and 7037-3 props, and the 1550KV on 6-inch GF 6032-3 and 6040-3 props and the GF 7037-3. (VCI spec sheet)
Battery
6S; VCI rates both KVs for 6S (24 V). (VCI spec sheet)
Frame
Four M3 holes on a 19 × 19 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:

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.

BatteryVoltsNo-load rpm (KV × V)Electrical frequencyESC steps per second
4S nominal14.819,9802,331 Hz13,986
4S full16.822,6802,646 Hz15,876
6S nominal22.229,9703,497 Hz20,979
6S full25.234,0203,969 Hz23,814

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.
