I'd imagine so, you would just need to gear down with the 6s to acheive the same approx speed as with the 5s pack, that would drive up your efficiency and lower the temps on the esc and motor, all ( other ) things being equal. Runtime would increase as a result if you were to use the same capacity & C rating as before ( 6s vs 5s - I'd venture that a lower C rated pack will hit the lvc sooner than the higher rated pack, even with the same mah capacity, depends how hard you push it really ), so for just bashing I'd say get the 5800mah 30c pack,- and a stop watch
