The SkyRC Racing Star Professional Tire Warmer offers updated features that make it ideal for racing at all levels. The package comes with updated silicone 1/10 scale heating cups for touring car. But, long tire warmer belts are available (SKY-600064-03 - not included) that allow this tire warmer to be used for no prep drag racing, short course, oval, 1/8 GT and 1/8 buggy applications! The system offers dual power source options, with the ability to use a 4S LiPo battery through an XT60 port, or 12-18V DC input using the included cable to power the system from a power supply. The menu is simple to navigate using the joystick, and LEDs for each tire indicate the status of the heating process. Plus, the temperature can be set independently for the front and rear to allow you to tailor the setup for various conditions.
