This is the Team Losi Speed-T Ready-to-Run Brushless Electric Truck.  Equipped with a Losi Xcelorin 4800Kv Brushless Power System, this truck is capable of speeds over 65 MPH when using a LiPo battery setup.  To keep this power under control, the truck includes a "Quick Programming Card" which allows you to change some of the ESC settings.  There are beginner and expert driving profiles, which allow you to tone down the power for the younger ones, or until you get used to the truck.  You can also limit the throttle if you choose to.  The Speed-T RTR also includes a 2.4GHz radio system featuring Spektrum technology.  This allows you to run the truck without the fear of radio interference, which would be a disaster at 65 MPH!

Bring the heat up and down your street with Losi’s fastest electric RTR ever, the Speed-T. Based on a proven, durable chassis design and ultimately an agile suspension setup, the Speed-T has the foundation to handle serious acceleration unlike any other RC truck. Losi’s revolutionary brushless power system, featuring an Xcelorin programmable electronic speed control and potent brushless motor, propels the Speed-T to top speeds in excess of 65mph. Road Weapon low profile tires mounted on Losi SpokeZ 320 Series Chrome wheels and a lowered chassis hug the ground for high-speed handling, and an installed wheelie bar keeps the wheels down to put the power to the ground. The included Losi MTX Pro Radio System with Spektrum™ 2.4GHz DSM® Technology offers complete control without interference. The custom painted, low-profile aerodynamic body is designed with speed and downforce in mind for less aerodynamic drag and more traction. 

More on the Brushless Power System:
The Speed-T features Losi’s revolutionary brushless power system, allowing it to achieve speeds in excess of 65mph. The fully programmable, high-output electronic speed control can handle traditional Ni-Cd, NiMH or LiPo battery packs, and offers precise throttle and braking control. The brushless motor requires virtually no maintenance, while offering unmatched efficiency and speed. Additionally, the ESC offers tons of programming options, including adjustable throttle limits, selectable beginner and expert user profiles, and much more using the Quick Programming Card.

All of this combined makes the Speed-T the only choice for serious drivers in need of serious speed.
