The spin is an illustration: the model turns at 1/600 of the no-load speed, and it is a generic 2812 motor drawn from Xnova’s published sizes, not its exact design. Thrust, current and power are Xnova’s bench figures for the HQ8*4.5*3 tri blades prop at 22.2 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 HQ8*4.5*3 tri blades: 1,510 g of thrust, 20.0 A, 444 W, 3.40 g per watt.

On your quad

All-up weight650 g

18.9 : 1

Thrust to weight at full throttle: four motors pull 12,280 g with the HQ8*4.5*3 tri blades at 22.2 V.

At 60% throttle they pull 6,040 g, 9.3 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 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 bench run from 49.7 A (900KV, HQ 9 × 5 × 3, 25.18 V) to 57.0 A (1300KV, HQ 7 × 4 × 3, 22.2 V); the 1100KV draws 54.5 A. (Xnova 900KV prop data, Xnova 1100KV prop data, Xnova 1300KV prop data)
Props: Xnova tested the 900KV on an HQ 9 × 5, the 1100KV on an HQ 8 × 4.5 and the 1300KV on an HQ 7 × 4, all three-blades. Props fit the M5 shaft. (Xnova 900KV prop data, Xnova 1100KV prop data, Xnova 1300KV prop data, Xnova drawing)
Battery: 6S for all three KVs. (Xnova data list)
Frame: Four M3 screws, opposite holes 19 mm apart (the 19 × 19 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 red rings round the top of the bell and red cut edges on a ten-spoke top. (Xnova drawing, Xnova product photo, Xnova top photo)
Shaft. M5 thread, standing 16 mm above the bell. (Xnova drawing)
Base. Black, with four M3 holes, opposite holes 19 mm apart. (Xnova drawing, Xnova product photo)
Leads. 26 cm. (Xnova data list)

How fast it spins

KV is the motor’s no-load speed per volt. With nothing on the shaft, the 1100KV 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	16,280	1,899 Hz	11,396
4S full	16.8	18,480	2,156 Hz	12,936
6S nominal	22.2	24,420	2,849 Hz	17,094
6S full	25.2	27,720	3,234 Hz	19,404

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 28 × 12 mm stator, 34 mm bell, 25.8 mm height, 5 mm shaft and 19 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.
