you guys think the +8mm chassis makes a big difference? Does it make the car a little less aggressive? Also Im new to the electric side lol. I have a used ft b4.1 that I just bought. It has a lrp spx esc and I think a novak 7.5 motor. Think the 7.5 is way to over kill for me? The spx comp esc any good? Another dump question, It has a tekin lipo, I didnt know they make batteries but anyways its a 3400 23c. It this battery good enough? I have a 5000 40c think that would be better?
