The New motor and gearbox help power this thing along while also tucking better under the truck than the original gearbox and even the 2 speed. It's great as is for a transporter. You can add the 2 speed if you need more pulling power. The esc can accept it. The only difference with the new ecs receiver combo is this one does support sound I believe. It does have light ports and the extra port for the 2 speed.
