Ok so I'm gonna get the Night Crawler I think as my intro to crawling. Is the brushed motor good enough to get by with? Could I just drop this brushless motor in there with the ESC that's already supplied? Losi: 1/10 Xcelorin 17.5T Brushless Crawler Motor: Losi (LOSB9410) Would it be worth it? What are the most important upgrades to make right off the bat? Links are always helpful.
