The spin is an illustration: the model turns at 1/600 of the no-load speed, and it is a generic 2204 motor drawn from Xnova’s published sizes, not its exact design. Thrust, current and power are Xnova’s bench figures for the GF5125 prop at 14.8 V, read straight across between its throttle steps. Its data starts at 50% throttle.

What it pulls

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

At 60% with the GF5125: 570 g of thrust, 14.6 A, 216 W, 2.64 g per watt.

On your quad

All-up weight650 g

6.8 : 1

Thrust to weight at full throttle: four motors pull 4,440 g with the GF5125 at 14.8 V.

At 60% throttle they pull 2,280 g, 3.5 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 to pair it with

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

ESC: Full-throttle currents on Xnova's Gemfan 5125 bench run from 15.8 A (1700KV, 22.2 V) and 18.0 A (1800KV, 22.2 V) to 33 A (2900KV, 14.8 V). (Xnova 1700KV sheet, Xnova 1800KV sheet, Xnova 2900KV sheet)
Props: Xnova tested every KV on a Gemfan 5125. Props fit the T-mount top. (Xnova 1700KV sheet, Xnova 1800KV sheet, Xnova 2900KV sheet, Xnova drawing)
Battery: 5–6S (1700KV, 1800KV), 3–6S (2900KV). (Xnova 1700KV sheet)
Frame: Four M2 screws on a 12 mm circle (the 12 × 12 pattern). (Xnova drawing)

Bench data

Redrawn from Xnova’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:

Bell. Black, with a red top. (Xnova product photo)
Shaft. 1.5 mm, standing 3.6 mm above the bell; props bolt to four M2 holes on a 5 mm circle around it (T-mount). (Xnova drawing)
Base. Four M2 holes on a 12 mm circle. (Xnova drawing)
Leads. 16 cm. (Xnova 2900KV sheet)

How fast it spins

KV is the motor’s no-load speed per volt. With nothing on the shaft, the 2900KV 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	42,920	5,007 Hz	30,044
4S full	16.8	48,720	5,684 Hz	34,104
6S nominal	22.2	64,380	7,511 Hz	45,066
6S full	25.2	73,080	8,526 Hz	51,156

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 Xnova’s published sizes: the 22 × 4 mm stator, 27 mm bell, 15 mm height, 1.5 mm shaft and 12 mm mounting circle. Anything Xnova 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.
