5-inch FPV freestyle motor

T-Motor Pacer V2 P2306

The smoother of T-Motor's two Pacer V2 sizes, for 5-inch freestyle close to objects, in 1950KV for 5S–6S and 2550KV for 4S–6S; on T-Motor's 6S bench the 1950KV pulls 1701 g on a T5147 at full throttle.

  • 5-inch freestyle close to objects (bandos, woods, streets)
  • 5S–6S (1950KV) or 4S–6S (2550KV)
  • T-Motor 5-inch tri-blade props
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 2306 motor drawn from T-Motor’s published sizes, not its exact design. Thrust, current and power are T-Motor’s bench figures for the T5147 prop at 24.5 V, read straight across between its throttle steps. Its data starts at 50% throttle.

What it pulls

T-Motor’s own bench test, one line per prop. Drag across the chart to move the throttle; the model above follows.

At 60% with the T5147: 976 g of thrust, 15.0 A, 367 W, 2.66 g per watt.

On your quad

10.5 : 1

Thrust to weight at full throttle: four motors pull 6,804 g with the T5147 at 24.5 V.

At 60% throttle they pull 3,904 g, 6.0 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 $21.90

  • For smooth freestyle

    T-Motor says the P2306 V2 is smoother than the P2207 V2, with fine low-throttle control and a smooth mid throttle, for knife-edge gaps, hit gaps and orbits.

  • Made for close flying

    T-Motor's suggested places are bandos, low woods, streets and low buildings.

  • What changed for V2

    A single winding, custom magnets, a new prop grip that T-Motor says holds the prop tightly, and a titanium shaft for lower weight.

  • Bench data for both KVs

    Thrust, current, RPM and power in 5% steps from 50% throttle; at full throttle the 1950KV pulled 1560–1701 g on 6S and the 2550KV 1207–1351 g on 4S.

What to pair it with

Our reading of T-Motor’s numbers, so your build matches what the motor was tested with.

ESC
Peak current over 60 s is 39.7 A for the 1950KV and 40 A for the 2550KV. T-Hobby pairs it with T-Motor's P50A 4-in-1. (T-Motor drawing and specs, T-Hobby product page)
Props
T-Hobby lists T-Motor's P49436. On the 6S bench the 1950KV pulled 1560 g on the T5143S, 1669 g on the T5146 and 1701 g on the T5147 at full throttle. (T-Hobby product page, T-Motor test report)
Battery
5S–6S for the 1950KV, 4S–6S for the 2550KV. T-Hobby suggests a 4S 1550 mAh or 6S 1300 mAh 120C pack, for a take-off weight of about 700–720 g. (T-Motor drawing and specs, T-Hobby product page)
Frame
5-inch freestyle quads, per T-Motor. Four M3 holes on a 16 mm circle. (T-Motor product page, T-Motor drawing and specs)

Bench data

Redrawn from T-Motor’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 1950KV 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 nominal14.828,8603,367 Hz20,202
4S full16.832,7603,822 Hz22,932
6S nominal22.243,2905,051 Hz30,303
6S full25.249,1405,733 Hz34,398

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 T-Motor’s published sizes: the 23 × 6 mm stator, 28.6 mm bell, 18 mm height, 16 mm mounting circle and 12 teeth and 14 magnets. Anything T-Motor 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.
