Max thrust is the maker’s own bench figure at full throttle, for the motor’s main KV version on the strongest prop it tested. From is the lowest price we saw at a store that had it in stock; some stores only sell sets of four, and the motor’s page has each store’s note.

Each motor

Its page has the maker’s specs with a source for every value, the bench data where it’s published, where to buy it, and a 3D model drawn from its numbers.

How many of these motors are from each brand, most first. Each brand’s page compares all of its motors, every size.
