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 2207 motor drawn from VCI’s published sizes, not its exact design. Thrust, current and power are VCI’s bench figures for the GF 5129-3 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 5129-3: 654 g of thrust, 11.4 A, 273 W, 2.40 g per watt.

On your quad

11.4 : 1

Thrust to weight at full throttle: four motors pull 7,396 g with the GF 5129-3 at 24 V.

At 60% throttle they pull 2,616 g, 4.0 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 $24.90

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 45.16 A (2120KV) and 46.89 A (2160KV) at 24 V; pick an ESC rated above that per motor. (VCI spec sheet)
Props
VCI tested both KVs on a GF 5129-3 and an HQ R29-3 at 24 V; the GF 5129-3 made the most thrust at full throttle. (VCI spec sheet)
Battery
6S; VCI rates both KVs 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:

How fast it spins

KV is the motor’s no-load speed per volt. With nothing on the shaft, the 2120KV 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 nominal14.831,3763,661 Hz21,963
4S full16.835,6164,155 Hz24,931
6S nominal22.247,0645,491 Hz32,945
6S full25.253,4246,233 Hz37,397

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, 26.4 mm bell, 20 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.
