1804 FPV Motors

3 motors with a 1804 stator from 3 brands, typically spinning 4-5in props. They weigh 13.3–14.0 g and come in 2400–3500KV windings. The name is the stator size in millimetres: a 1804 stator is 18 mm across and about 4 mm tall.

1804 thrust from manufacturer bench tests

2 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.

How to read these columns: reading motor bench tables. Turn thrust into a build's thrust-to-weight ratio with the TWR calculator.
