@ Semi Pro, ah, fair enough- women and their 'to-do' lists
Ditto what nuz69 said- 5s, with a 1580kv motor in a 12lb truck, geared for 50mph is too much- little wonder the motor is pulling tonnes of current and heating up the esc and wires really quickly, with poor runtime. 6s and gear for 40-45mph should give much better results.
