3115 FPV Motors
4 motors with a 3115 stator from 4 brands, typically spinning 8in+ props. They weigh 98.0–113.4 g and come in 400–1050KV windings. The name is the stator size in millimetres: a 3115 stator is 31 mm across and about 15 mm tall.

3115 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 |

| EMAX ECO II 3115 | 5270 g | 49.3× | — | 500KV, HQ 10x5x3, 10S |
| T-Motor V3115 3115 | 4817 g | 42.5× | 5.1 | 400KV, T-Motor T10.5X5-3, 12S |
