1S tiny whoop motor

RCinPower GTS V3 0802

A 1.97 g motor for 1S whoops: an 8 × 2 mm stator on two ball bearings and a hardened 1 mm shaft, pulling 51 g per motor on RCinPower's 3.7 V bench (25000KV, Gemfan 1636 four-blade).

  • 1S brushless tiny whoops
  • 31 mm and 40 mm props
  • 1S (22000KV–27000KV) or 2S (10000KV)
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 0802 motor drawn from RCinPower’s published sizes, not its exact design. Thrust, current and power are RCinPower’s bench figures for the Gemfan 1636 prop at 3.7 V, read straight across between its throttle steps. Its data starts at 50% throttle.

What it pulls

RCinPower’s own bench test, one line per prop. Drag across the chart to move the throttle; the model above follows.

At 60% with the Gemfan 1636: 33 g of thrust, 3.0 A, 11 W, 3.31 g per watt.

On your quad

0.3 : 1

Thrust to weight at full throttle: four motors pull 204 g with the Gemfan 1636 at 3.7 V.

At 60% throttle they pull 130 g, 0.2 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

  • Two ball bearings

    RCinPower uses two bearings instead of the oil-impregnated bushing of many 0802 motors, and claims longer life, quicker low-speed response and less heat.

  • Hardened 1 mm shaft

    Made to fit props from any brand with a close fit, RCinPower says.

  • Leads on a PCB pad

    The leads are soldered to a PCB pad so vibration and bending during builds don't break them at the stator. A 1.25 mm plug is fitted, for most whoop flight controllers.

What to pair it with

Our reading of RCinPower’s numbers, so your build matches what the motor was tested with.

ESC
On RCinPower's 3.7 V bench the 1S versions peak at 5.6 A (22000KV), 6.5 A (25000KV) and 7.2 A (27000KV), all with the Gemfan 1636 four-blade. (RCinPower 10000KV and 22000KV sheets, RCinPower 25000KV and 27000KV sheets)
Props
Tested with Gemfan 1220 (31 mm) and Gemfan 1635/1636 (40 mm) props. The 40 mm four-blade pulls the most; with 31 mm props the 25000KV runs cooler (58–60 °C). (RCinPower 10000KV and 22000KV sheets, RCinPower 25000KV and 27000KV sheets)
Battery
1S for 22000KV, 25000KV and 27000KV; 2S for the 10000KV. (RCinPower 10000KV and 22000KV sheets, RCinPower 25000KV and 27000KV sheets)

Bench data

Redrawn from RCinPower’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 25000KV 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 nominal14.8370,00037,000 Hz222,000
4S full16.8420,00042,000 Hz252,000
6S nominal22.2555,00055,500 Hz333,000
6S full25.2630,00063,000 Hz378,000

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 RCinPower’s published sizes: the 8 × 2 mm stator, 11.2 mm bell, 8.2 mm height, 1 mm shaft, 6.6 mm mounting circle and 9 teeth and 12 magnets. Anything RCinPower 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.
