I have a electric rustler. It has a green speed gem motor and a lrp esc. I think everything is hook up correct ut I am not sure. When you plug the battery in the truck takes off. When you give it throttle is does nothing. When you hit the reverse it stops. After about a minute the battery pak starts smoking. What do i have wrong? How can I fix it? I know nothing about electric. More of a nitro guy! Any help or suggestions would be appreciated. Thanks
