I use a 60a trackstar esc, although the hw 60a or similar will be fine, I raised the body mounts though so it had room under the shell, I run 19t pinion on the 2838 5200kv leopard motor and it is better than the stock motor I have been side by side with my son's running stock motor which can be used ok with the 35a esc but I feel the 60a gives that extra secure feeling that it can handle everything and keep the temps under control but each to there own.
