How to tune my nitro rc car? - used cheer mats

I bought a Hyper 7 Nitro Buggy This is my first car and I have no idea how, if I start as soon as the wheels begin to spin, and when the brakes even on the seats of use

There are no instructions that came with the car

any help would be very grateful
