Don't launch. If you do, don't be surprised when you blow your diff and brake axels. These cars aren't made for that (at least not stock) You may not break right away, but at some point... You will. Its just like donuts. It only takes 1 time to turn your motor into a paperweight. I realize this is off topic but if you asked about launching, you probably will attempt a donut. These motors are built sideways, and doing flat spins forces all the oil from one side to the other, starving it and blowing it up within seconds. 2 main rules with these cars 1. Don't launch 2. Don't flat spin.
