I see a lot of u guys are running the bigger packs 7200mah ect, I know a lot of guys are getting away with high end high C rated shorties also correct? Guy on here a lot from Ohio Samrus or something like that he posted picks of the carbon air dams recently, he runs shorties which is what I was gonna try, I just got my truck this past Friday its my first 4wd anything, gonna race in Dallas tx at mikes small indoor tenth scale track with low to med traction and was gonna get the Tekin pro4 HD 3500kv should be plenty? Track is prob like 40 50ft by 30ft I'm thinking. I have no idea where to start with anything, help me out guys like diff oils? spur pinion? gonna use the stock springs I guess cuz there soft and its low to med traction track. Pistons I want to try the Fioroni's or the Competition Suspension Pistons they should and better be awesome for 48 bucks. I know some of u guys are running them, the F's what oil weight would u suggest for low to med traction track and what springs? Anyone trying Avid or Kyosho springs? Thanks guys.
