Losi 8ight Buggy setup?

Well, if you were running a different ESC, I'd recommend 5s or 6s on a higher turn motor to reduce the current.

What about using a higher capacity pack, which will heat up less than a smaller capacity pack on a given current.

What are your battery trays made of? If plastic, it will hold the heat in. Maybe some strategically placed holes to help airflow? If metal, the holes might still be a good idea since most people use some kind of padding reducing the heatsink properties of the metal.
