5-inch FPV freestyle motor

Xnova 2207 Hard Line V2

Xnova's 2207 Hard Line V2 for 5-inch freestyle and cinematic flying, 34.5 g; the 1900KV pulls 1,848 g on an HQ Ethix S5 at 22.2 V in Xnova's test.

  • 5-inch freestyle and cinematic flying
  • 6S (1650KV, 1800KV, 1900KV), 4–5S (2150KV) or 3–4S (2450KV, 2600KV)
  • 5-inch props on an M5 shaft
Drawing the 3D model…

The spin is an illustration: the model turns at 1/600 of the no-load speed, and it is a generic 2207 motor drawn from Xnova’s published sizes, not its exact design. Thrust, current and power are Xnova’s bench figures for the HQ S5 Ethix prop at 22.2 V, read straight across between its throttle steps. Its data starts at 10% throttle.

On your quad

11.4 : 1

Thrust to weight at full throttle: four motors pull 7,392 g with the HQ S5 Ethix at 22.2 V.

At 60% throttle they pull 3,824 g, 5.9 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 you get for $29.00

  • Six KVs, 34.5 g

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:

How fast it spins

KV is the motor’s no-load speed per volt. With nothing on the shaft, the 1900KV 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.

BatteryVoltsNo-load rpm (KV × V)Electrical frequencyESC steps per second
4S nominal14.828,1203,281 Hz19,684
4S full16.831,9203,724 Hz22,344
6S nominal22.242,1804,921 Hz29,526
6S full25.247,8805,586 Hz33,516

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 × 7 mm stator, 28.1 mm bell, 19.4 mm height, 5 mm shaft and 16 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.
