I have intalled the following-Trenchers/Desperados,Tekno axles front/rear,body lowering kit and a Traxxas fan for the esc.I have on the way Traxxas big bore shocks,T-Bone front/rear bumpers and wheelie bar.LOVE this truck so far!!!I run 2S lipo's right now,but plan to get at least one 3S pack.I noticed Integy offers single and dual fan setups for the motor,would getting the single be enough or should i get the dual?Also any other bolt ons i should check out at this point?
