FPV Motor Reference Guide

The sections linked below will give you information about similar-sized motors. When I talk about similar-sized motors, what I mean is the ratio of stator width to stator height (not simply stator volume). If you’re looking to change motors on a quad, then you need to choose motors with a similar ratio. This will ensure a similar type of flight performance to your current setup.

The categories below list all the well-known motor sizes and compare the stator volume of similar shaped motors.
