5-inch FPV freestyle motor
MEPS NEON 2207 V2
A 5-inch freestyle motor: 36 g with leads, a 6082 aluminium shell, N50H magnets and NMB bearings, and up to 1817 g of thrust per motor on MEPS's 25.2 V bench (2050KV, SZ5145).

- 6S (1950KV, 2050KV) or 4S (2550KV)
- 5-inch three-blade props (MEPS SZ5145, SZ4942)
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 MEPS’s published sizes, not its exact design. Thrust, current and power are MEPS’s bench figures for the MEPS SZ5145 prop at 25.2 V, read straight across between its throttle steps. Its data starts at 10% throttle.

What it pulls
MEPS’s own bench test, one line per prop. Drag across the chart to move the throttle; the model above follows.
At 60% with the MEPS SZ5145: 1,000 g of thrust, 15.5 A, 384 W, 2.60 g per watt.
On your quad
10.5 : 1
Thrust to weight at full throttle: four motors pull 6,796 g with the MEPS SZ5145 at 25.2 V.
At 60% throttle they pull 4,000 g, 6.2 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 $10.99
Up to 1817 g
MEPS's 2050KV pulls 1817 g at full throttle on 25.2 V with its SZ5145 prop; the 1950KV pulls 1699 g.

What to pair it with
Our reading of MEPS’s numbers, so your build matches what the motor was tested with.

Bench data
Redrawn from MEPS’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:
- Shaft. 5 mm stainless steel, M5 thread 8 mm long (the material is from MEPS's page (S1)). (MEPS size chart)
- Bell. 6082 aluminium shell, one-piece aluminium rotor. (MEPS product page)
- Magnets. N50H. (MEPS product page)
- Stator. The coils are wound on a stack of thin steel laminations: 22 × 7 mm (2207) (MEPS's page calls 2207 the stator size). (MEPS product page)
- Bearings. NMB. (MEPS product page)
- Base. 4 × M3 holes on a 16 mm circle. (MEPS size chart)
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.
| Battery | Volts | No-load rpm (KV × V) | Electrical frequency | ESC steps per second |
|---|---|---|---|---|
| 4S nominal | 14.8 | 28,860 | 3,367 Hz | 20,202 |
| 4S full | 16.8 | 32,760 | 3,822 Hz | 22,932 |
| 6S nominal | 22.2 | 43,290 | 5,051 Hz | 30,303 |
| 6S full | 25.2 | 49,140 | 5,733 Hz | 34,398 |
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 MEPS’s published sizes: the 22 × 7 mm stator, 28.3 mm bell, 19.3 mm height, 5 mm shaft, 16 mm mounting circle and 12 teeth and 14 magnets. Anything MEPS 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.
