How to make my Rc petrol car faster

[joshgoh]

Hi

I have a shengqi hummer and when i run it, it sounds like it is not running flat out. It goes about 20mph which is slow when its supossed to do like 40mph+. How could i improve this as i want it to go faster. Any Suggestions on this?

Might bring it down this sunday as well as my baja?

Hopefully see you this sunday. If i can get down there. and wheather dependant.
