So I found a Bardwell video on accident and because the motors being mentioned are similar but smaller and a higher KV than the ones I recently bought I thought "hmmm, what is this"... then I started watching the video and discovered how involved the discussion was. 

While this video claims to be about a specific motor... the whole discussion is amazing! I am only half way through and already learned way more than I expected. This is perfect for my current thirst for more advance knowledge that I am going through right now. 

(sorry in advance if someone else has already posted this one)

Great video indeed
