Novak Brushless - fan or no fan? and Gearing?

No need to mill the ESC. You can use the std b4 body with the 25mm fan. You just need to cut the 2 outside holes off the fan and mount it on top of the speedo but to the side next to the cells. 7.2 is also good. The new ESC with sintered run much cooler. You can run the 2wd at tracks like Kiddy and Tiverton without the fan but you may as well leave it in as it will be better for all equipment

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 FET´s over to the Zink is one big joke,there is almost 2mm thick paste between the zink and FET´s there is 2 reasons why it´s 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

Seems very drastic tbh..

If you run a fan though, the speedo doesnt actually get that hot, with a 5.5 and the fan on top, my speedo is merely warm. Sintered rotors have made a massive difference.

Good luck if it all holds out for you bud.
