5-inch FPV freestyle motor
MEPS NEON COOL 2207
A 5-inch freestyle motor in CW and CCW versions with direction-specific bell ribs: 34 g with leads, a TC4 titanium hollow shaft and N52SH magnets, and 1734–1745 g of thrust at full throttle on MEPS's 25.2 V bench (SZ5145).

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: 1,006 g of thrust, 15.4 A, 383 W, 2.60 g per watt.
On your quad
10.7 : 1
Thrust to weight at full throttle: four motors pull 6,980 g with the MEPS SZ5145 at 25.2 V.
At 60% throttle they pull 4,024 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 $11.99
About 1.74 kg on 6S
On MEPS's 25.2 V bench with its SZ5145 prop the CCW motor pulls 1745 g at full throttle and the CW motor 1734 g, both at 43.8 A.

What to pair it with
Our reading of MEPS’s numbers, so your build matches what the motor was tested with.
- ESC
- MEPS's peak current is 43.8 A, the full-throttle draw of its SZ5145 tests, so a 45 A or larger ESC covers it. MEPS's guide names BLHeli_32 or AM32 stacks such as its NEONCORE F405 60A. (MEPS spec table, MEPS data test, MEPS product page)
- Props
- MEPS tested its SZ5145 and SZ4942 three-blade props; the SZ5145 pulls 135–150 g more at full throttle. (MEPS data test)
- Battery
- 6S; MEPS's guide suggests a 1050–1400 mAh 120C or higher pack. (MEPS spec table, MEPS product page)
- Frame
- Four M3 screws on a 16 mm circle (the 16 × 16 pattern of 5-inch frames). Mount the CW and CCW motors on the matching corners. (MEPS product page, MEPS size chart)

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 (± 0.05 mm) TC4 titanium alloy, hollow (the material is from MEPS's page (S1)). (MEPS spec table)
- Bell. Direction-specific ribs (CW and CCW versions) and a textured anti-slip prop flange. (MEPS product page)
- Magnets. N52SH arc magnets (the variant description on the same page says N52H). (MEPS product page)
- Stator. The coils are wound on a stack of thin steel laminations: 22 × 7 mm (2207) (MEPS's description gives 22 × 7 mm). (MEPS product page)
- Winding. Single-strand high-purity copper wire. (MEPS product page)
- Base. 4 × M3 holes on a 16 mm circle (16 × 16 mm). (MEPS product page, 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, 29 mm bell, 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.
