Displaying on the stand of Swedish company Minicars is a new time keeping system from a company calling themselves Dirt Champ Design. The timing system is aimed at racers that want to check their own times on practice days or for clubs who want a simple timing system. Sold as a package with the hardware, which is placed next to the track on the supplied tripod, and the timing software, the unit can handle an unlimited number of their own unique transponder and is completely wireless using bluetooth. It is powered using a LiPo cell and can be charged with the supplied USB cable, while the transponders use the power from a BEC or RX pack. Set to be available in April.
