electric revo questions

OK if i understand well, the easy and cheapest way to convert my revo is to take a RcMonster motor mount, put my 9L on it, install a FOC kit on the tranny (because i don't want to have reverse), installl a better pin on the input shaft and lodk the tranny in second gear (i'll want to keep a servo for the break, don't want to break with the motor to drain less current from the batt) and buy a FlightPower 5000mAh, 14.8 volts li-po pack??? That's it??
