viperkilla,
were talking about the white paste you will find under the esc/servo chips.This paste helps transfer the heat from the chips to the aluminum heatsink buried in the bottom of the Xmod chassis.
I paid way more than $1.99 I got ripped off
my total came to $41. bucks oh hey wait thats right I bought some Xmod stuff lol.
They should just include the paste with the stage 2 kit or AWD kit or the Xmod car kit itself.
