Will I need to use lipo batteries with this?
You do not need LiPo to run a mild to intermediate brushless system. LiPo is better than NiMh, but not a requirement. As long as you don't gear aggressively and go crazy with extreme starts & stops on a high-traction surface or driving through thick grass, most 3000mah+ NiMHs will handle a system like this.
By now you must have visited the local hobby shop. What did you find? Did they even have any brushed motors at all?
Many don't anymore.
