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 material which make it looks Amazing compare to other materials BUT this version is not high temperature resistant, please always check the cooler before and after the ride if there is no any visible damage !!
