I'm thinking about getting a L4 and since I've never drove a 12th scale before I had a few questions. Whats a good servo for it? Do I have to do anything different on the mounting if I use a mini servo? Do I need to change the T-plate out for carpet? What spur should I start with for stock and 19t? Any parts I should stock up or springs? And whats a good tire to start off with for med/low bite carpet? Thanks.
