I was running the 10L motor in my converted buggy and it was plenty fast. You might be suprised. Those buggies dont weigh much especially if you get a lipo. An XL motor might be overkill. The 10L was breaking the metal cvds right off my buggy. The warrior also isnt a bad speed controller. 300 seems like a pretty good price for everything.
I would install the mamba so you can set punch control. You will probably want to tone it down some.

Wow I gave the exact opposite advice as everyone here. You guys must be serious speed junkies. The 10L would lay 10+ feet of rubber on the pavement. It had so much power I had to buy a second buggy for parts cause they kept breaking because of all the power. Once of the hardened steel cvd's broke right in the center. I have never seen anything like that before.

I dont know if it makes any difference, but I had the rd logics sho buggy. Maybe its not as strong but it looks just like the one you got. Yeah thats the emaxx motor plate. I did the same thing. All it took was 2 holes, cut a piece off the bottom and it worked perfect.
