1103 FPV Motors
5 motors with a 1103 stator from 3 brands, typically spinning 40-65mm whoop/micro props. They weigh 3.2–4.6 g and come in 7000–11000KV windings. The name is the stator size in millimetres: a 1103 stator is 11 mm across and about 3 mm tall.

| BetaFPV | Aquila20 1103 | 10500 | 3.5 g | 2S |
| Happymodel | EX1103 | 7000 | 3.7 g | 1-2S |
| Happymodel | EX 1103 | 11000 | 3.8 g | 1-2S |
| T-Motor | M1103 | 8000, 11000 | 4.6 g | 2-4S |
1103 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 |
|---|---|---|---|---|
| T-Motor M1103 | 238 g | 51.7× | — | 11000KV, GF2015-2, 3S |
| BetaFPV Aquila20 1103 | 142 g | 40.6× | 2.85 | 10500KV, GF 2218-3, 2S |
| Happymodel EX 1103 | 122 g | 32.1× | — | 11000KV, 2023R propeller, 2S |
