Rallycross

Based on the FIA World Rallycross Championship the aim is to bring this fast paced and close contact racing formula into the reach of all racers. Based on shaft drive 1/8th scale E-buggies these fast, tough and thrilling cars are modified to run on a tarmac surface. The use of low ramps and astroturf cut throughs allow a multitude of track layouts. The Joker lap means that picking the right strategy is crucial.

Run as a series of qualifying and final races it fun, close competitive racing all the way.
