I just found your channel. I'm glad I did. You're very informative. My viewers often ask me questions that I don't quite know the answers to, now I have a place to refer them to find some in depth answers.

Awesome! Thank you! Glad you found the channel and it's helpful.

Another pros and cons of high vs low kv motors is that a high kv motor is not eficient, doesnt have much torque it kills the escs because of the low voltage and high amperage frequency that the esc needs to work in order to spin that motor that fast, motor overheats very fast basically a high kv motor is not efficient in any way and the low kV motors are the complete opposite because they spin slower but can take a lot higher voltage meaning that its going to work very efficiently with the esc lower kV doesn't mean that its going to be slower you can change the gearing in order to go a lot faster because low kV motors have a lot more torque than high kV motors in a lot of cases lower kV motors go faster than high kV motors

I recently bought a 6500kv motor, is this something that can be good for a speed run car?
I should mention I'm trying to avoid anything more than 3s or 4s

I'm looking for a high RPMs motor for a centrifuge, so it also has to rotate about 5kg of weight (about 1.5~2kg of the fluid to be filtered, and about 2~3kg of the spinning cylinder+rotating-rod).
I see that smaller rc motors can hit higher RPMs, I assume because they are not supposed to rotate much mass.
The centrifuge won't have to run for a long time. Actually the higher the RPMs the much shorter the run time would need to be, as the centrifugal force increases with the square of the RPMs.
But I'm not familiar with el.motors specs.
Do you guys have any recommendations or advices?

These videos are excellent! It really helps people understand things where there are a lot of misconceptions!
Keep up the great work!

Thanks for the awesome comment, Brian!

Maybe slow it down a bit! Too many motors going too fast!

I see what you did here 😜
