A tip, i was planning to convert my GTB to a 1:12 GTB/ESC, after removing the heatzink i almost started to cry...the worst ive ever seen..the so called thermalpaste, that should transfer the heat from the FETīs over to the Zink is one big joke,there is almost 2mm thick paste between the zink and FETīs there is 2 reasons why itīs there dust and maybe little waterproofing, and trensfer the heat over...but thats BS for the last one.. many years in the overclocking world with computer and there is NO way that transfer is good, id say less than 60 % or maybe more... so i removed it asap, used real thermalpaste,and fixed a own frame raound it for dust, and put it together i mean i mounted the zink direkt on the fets with some paste between...i must say the heat transfe is SICK better now..
This will take out the guarantie,and only recomend to guys that can handle the driver
