Best motors for 2.5″ tri-blade props on 2S

In collaboration with Quad66 (please subscribe to his YouTube channel!), we tested various motors that will pair well with the Gemfan 2512 tri-blades on 2S. He did an amazing job with using statistical analysis to objectively figure out which is the category-best amongst the motors.

The Motors

We added a few more motors to the list and also disqualified some after initial testing reveals them to be either too small to swing 2512s, or too large/heavy for the application.
