Cinewhoop and 4- to 5-inch FPV motor

Xnova Lightning 2203.5 V2

Xnova's Lightning 2203.5 V2 for cinewhoops, 19–21 g with a hollow titanium shaft; the 2800KV pulls 830 g on a Gemfan D76 at 22.2 V in Xnova's test.

The spin is an illustration: the model turns at 1/600 of the no-load speed, and it is a generic 2203.5 motor drawn from Xnova’s published sizes, not its exact design. Thrust, current and power are Xnova’s bench figures for the GF D76 prop at 22.2 V, read straight across between its throttle steps. Its data starts at 10% 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 GF D76: 465 g of thrust, 20.4 A, 453 W, 1.03 g per watt.

On your quad

All-up weight650 g

5.1 : 1

Thrust to weight at full throttle: four motors pull 3,320 g with the GF D76 at 22.2 V.

At 60% throttle they pull 1,860 g, 2.9 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 22.2 V bench run from 15.1 A (1800KV, Gemfan 5125) to 33.3 A (2800KV, Gemfan D76); the 2400KV draws 23.2 A on an HQ 4 × 4.3 three-blade. (Xnova 2800KV prop data, Xnova 2400KV prop data, Xnova 1800KV prop data)
Props: Xnova tested the 2800KV on a Gemfan D76, the 2400KV on an HQ 4 × 4.3 three-blade, and the 1800KV on a Gemfan 5125 and an HQ S4. Props fit the M5 shaft. (Xnova 2800KV prop data, Xnova 2400KV prop data, Xnova 1800KV prop data, Xnova drawing)
Battery: 4S–6S for all three KVs; Xnova tested each on 22.2 V. (Xnova data list, Xnova 2800KV prop data, Xnova 2400KV prop data, Xnova 1800KV prop data)
Frame: Four M2 screws, opposite holes 12 mm apart (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 ring round the top of the bell and red cut edges on a six-spoke top. (Xnova product photo, Xnova top photo)
Shaft. Hollow titanium with an M5 thread, standing 13 mm above the bell. (Xnova product page, Xnova drawing)
Base. Four M2 holes, opposite holes 12 mm apart. (Xnova drawing)
Leads. 22 AWG, 6 cm. (Xnova data list)

How fast it spins

KV is the motor’s no-load speed per volt. With nothing on the shaft, the 2800KV 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	41,440	4,835 Hz	29,008
4S full	16.8	47,040	5,488 Hz	32,928
6S nominal	22.2	62,160	7,252 Hz	43,512
6S full	25.2	70,560	8,232 Hz	49,392

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 × 3.5 mm stator, 27 mm bell, 15.3 mm height, 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.
