What Diver said is true , if you slam on the brakes you will spin out you can compensaite for this by modulating the brakes, pumping them and doing your hard braking toward the end of the straight away before you go into the turn. You can also dial out some of your brakes thru adjustment of your linkage or your radio control unit if it has the capability. But to get this setup to work for you , you will have to practice, practice.
