Xnova T1804

What it pulls

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

What you get

• Five KVs

  From 1900KV for 5–6S to 3500KV for 3S, each with its own data sheet.

• T-mount top

  Props bolt to four M2 holes on a 5 mm circle in the bell's top, around a 1.5 mm shaft.

• Smooth and balanced

  Xnova lists low cogging torque and smooth running, and says the motors are precisely balanced and fully tested.

• Bench numbers

  On a Gemfan 5125 the 2800KV pulls 530 g at 16.2 A on 11.1 V and 710 g at 22.5 A on 14.8 V.

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 13.0 A (2400KV, HQ 4 × 2.5, 18.5 V) to 28.5 A (3100KV, Gemfan 5125, 14.8 V); the 2800KV peaks at 22.5 A on 4S. (Xnova 2400KV sheet, Xnova 2800KV sheet, Xnova 3100KV sheet)

Props

Xnova tested mostly the Gemfan 5125, plus HQ 5 × 3 and 4 × 2.5 two-blades on the 2400KV. Props fit the T-mount top. (Xnova 1900KV sheet, Xnova 2400KV sheet, Xnova drawing)

Battery

5–6S (1900KV), 4–5S (2400KV), 3–5S (2800KV), 3–4S (3100KV), 3S (3500KV). (Xnova 1900KV sheet)

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 an orange-red anodised top. (Xnova product photo)
• Shaft. 1.5 mm, standing 3.8 mm above the bell; props bolt to four M2 holes on a 5 mm circle around it (T-mount). (Xnova drawing)
• Base. 2.8 mm thick, with four M2 holes, opposite holes 12 mm apart. (Xnova drawing)
• Leads. Silicone wire, 10.5 cm. (Xnova 2800KV sheet)

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.

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 18 × 4 mm stator, 23 mm bell, 13.7 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.
