ELECTRIC MOTOR SYSTEMS
INNOV8TIVE DESIGNS https://innov8tivedesigns.com/ specializes in RC aircraft power systems, supplying motors, ESCs, props, and all manner of other components, in addition to excellent product and customer support.
They also have the best and most complete description of how to size all the components of an electric motor system, written by Lucien Miller. You can read it here: https://innov8tivedesigns.com/resources/lucien-s-blog.html
It's a fairly long blog, so I suggest printing it out (6 pages) so you can read it at your leisure and make notes in the margins for your particular setup.
