Brushless motor and controller for under 700$

Hey fellas,

Thanks for the reply. This is not a show truck. I will however be running it in any terrain you can think of (asphalt, dirt roads, wood chippings, sand, mud and just about anything I can think of to try to have fun). I am not satisfied with just 38mph. I am aiming for 50+mph on asphalt. How much money and what parts will I need to meet or exceed my goals?

Thanks fellas.

Brandon
