Brushless motor #1 killer is overheating, Temperature difference between the motor shell and inner coil can be even 1:2 so if motor shell is 50C then inside the motor could be even over 100C so as you can imagine any temperature drop counts.
!! To make this cooler I used one of the Best materials available on the market, it' much stronger compare to other and can handle higher temperatures !!
