HV-Maxx or something else?

Thanks for the info guys. Like i said i never use 12 cells all i have is 7 cell packs so whatever motor i get will be on 14 cells for now and maybe later i will add more cells.

I found out that the max i have has UE 6 diffs installed! I don't race on no track or anything all i really do is speed runs, i have a really big yard!

I would like to drag race my friends HV-Maxx and blow him away. Speed wise i'd like to get as fast as it will go. I don't think 40mph is fast anough don't the HV-maxx go close to that?
