1.6–2-inch 1S–2S micro FPV motor

VCI Spark 1102

A 3.3 g motor for 1.6- to 2-inch micros; on VCI’s 8 V bench the 11000KV pulls 101 g at full throttle on a GF 2023-3.

  • 1.6- to 2-inch micro quads
  • 2S (11000KV, 13000KV) or 1S (21000KV)
  • Gemfan 1635-3 and 2023-3 props (VCI’s test props)
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 1102 motor drawn from VCI’s published sizes, not its exact design. Thrust, current and power are VCI’s bench figures for the GF 2023-3 prop at 8 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.

05010015030%40%50%60%70%80%90%100%gthrottle101 gGF 2023-392 gGF 1635-3

At 60% with the GF 2023-3: 54 g of thrust, 3.6 A, 29 W, 1.89 g per watt.

On your quad

0.6 : 1

Thrust to weight at full throttle: four motors pull 404 g with the GF 2023-3 at 8 V.

At 60% throttle they pull 216 g, 0.3 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 $21.20

  • About 100 g on 2S

    On VCI’s 8 V bench the 11000KV pulled 101 g on a GF 2023-3 at 8.82 A, and the 13000KV 105 g on a GF 1635-3 at 9.26 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 8.82 A (11000KV) and 9.26 A (13000KV) at 8 V, and 7 A (21000KV) at 4 V; pick an ESC rated above that per motor. (VCI spec sheet)
Props
VCI tested the 1.6-inch GF 1635-3 and the 2-inch GF 2023-3. (VCI spec sheet)
Battery
2S for the 11000KV and 13000KV, 1S for the 21000KV, as VCI rates them. (VCI spec sheet)
Frame
Four M2 screws on a 9 × 9 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 11000KV 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 nominal14.8162,80016,280 Hz97,680
4S full16.8184,80018,480 Hz110,880
6S nominal22.2244,20024,420 Hz146,520
6S full25.2277,20027,720 Hz166,320

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 11 × 2 mm stator, 14.2 mm bell, 9.5 mm height, 1.5 mm shaft, 9 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.
