1.Awesome Brushless RC CarThis beast is equipped with a 45A brushless ESC and a 2845 quad-pole brushless motor, providing you with great power and lightning-fast response. 2.Speed Demon Hold on tight, because this bad boy can reach a top speed of 42 km/h out of the box. But guess what? If you put in a 3S battery (sold separately), you can push it to a whopping 55 km/h. That's fast, my friend!
