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 8.3 A (2700KV, Gemfan 3016, 22.2 V) to 10.0 A (4700KV, Gemfan 3016, 11.1 V); the 3800KV draws 9.5 A on 4S. (Xnova 2700KV sheet, Xnova 3800KV sheet, Xnova 4700KV sheet)

Props

Xnova tested every KV on a Gemfan 3016, and the 2700KV also on an HQ T3*2. Props fit the T-mount top. (Xnova 2700KV sheet, Xnova 3800KV sheet, Xnova 4700KV sheet, Xnova drawing)

Battery

5–6S (2700KV), 3–4S (3800KV), 3S (4700KV). (Xnova 2700KV sheet, Xnova 3800KV sheet)

Frame

Four M2 screws, opposite holes 9 mm apart (the 9 × 9 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 a red four-spoke top. (Xnova drawing, 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. 2.2 mm thick, with four M2 holes, opposite holes 9 mm apart. (Xnova drawing)
• Leads. 15.5 cm. (Xnova 3800KV sheet)

How fast it spins

KV is the motor’s no-load speed per volt. With nothing on the shaft, the 3800KV 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 14 × 4 mm stator, 18.6 mm bell, 12.8 mm height, 1.5 mm shaft and 9 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.
