RC cars and nitro car help please?

I got my very first RC nitro car it's the tornado s30 by redcat racing. I heard it was a good beginner car so I got that. I was wondering what else do I need to know that most beginners don't know before I wind up ruining the car. Like can I only run the car for a certain amount of time before it over heats? And how can I figure that out. And also can I take this buggy in the sand and into puddles. What do I need to do to take care of it? And do I need and other accessories with it? Please help
