The fan i installed did it's job today. The body postst didn't get hot. Only 3-4 lights on the esc with a 4.5t novak. probably i will reinstall the esc on the chassis in another way so the body postst are turned outside (they are now turned inside) and install the fan nearer to the posts. I still think tekin should consider to make a fan for it as proper hop up. Now i had to make a makeshift fan wich looks like it doesn't really belong on the chasis and it looks ugly as well lol
