1303 FPV Motors
4 motors with a 1303 stator from 4 brands, typically spinning 2-2.5in props. They weigh 6.1–7.5 g and come in 5000–6000KV windings. The name is the stator size in millimetres: a 1303 stator is 13 mm across and about 3 mm tall.

| Flywoo | ROBO 1303 | 6000 | 6.1 g | 2-4S |
| iFlight | XING 1303 | 5000 | 6.5 g | 3-4S |
| VCI HOBBY | Spark 1303 | 5400 | 7.1 g | 3S |
| FlyFishRC | Flash 1303.5 | 5500 | 7.5 g | 4S |
1303 thrust from manufacturer bench tests
3 of these motors come with the manufacturer's own thrust test. Each row is that motor's peak-thrust point, the prop and battery it was measured with, and the efficiency at 50% throttle in the same test. Every brand runs its own bench with its own props, so compare rows that share a prop and cell count; this is not one like-for-like test.
| Motor | Max thrust | Thrust ÷ motor weight | g/W at 50% | Tested with |
|---|---|---|---|---|
| Flywoo ROBO 1303 | 355 g | 58.2× | 2.32 | 6000KV, GF D51*4, 3S |
| VCI HOBBY Spark 1303 | 215 g | 30.3× | 3.3 | 5400KV, GF 2540-3, 3S |
| iFlight XING 1303 | 198 g | 30.5× | 2.76 | 5000KV, 2540, 4S |
How to read these columns: reading motor bench tables. Turn thrust into a build's thrust-to-weight ratio with the TWR calculator.
