so I am kinda wanting to upgrade but I really don't know what I need to consider I do realize that broken parts will happen much easier but I stilll want to upgrade. Tekin, mmm I don't know what is a good set up. Stock I seem to have plenty of power for crawling but I want the ability to go FAST!! I assume brushless is where I'm headed, or can I get a big fast brushed motor?

more questions to follow...hope I'm not breaking Traxxas rules AGAIN
