I used to have an arrma big rock wich I sold because it felt slow after I bought my kraton and got a taste of 6s but I kinda miss it cause I never had to work on it. I had it for 2 years and all I did was swap out an esc, upgrade shocks, and replace a rear diff. The kraton just seems like I'm constantly working on it. Wich of the 3s trucks would be the best for me?.
