The 18th The Dirt Nitro Challenge will be held from the 22nd to 26th of February at the Fear Farm R/C Raceway in Phoenix, Arizona. Joey Christensen and The Dirt crew will work their magic to create yet another set signature DNC tracks (1/10 track, 1/8 track, and 1/5 track). “Don’t miss out the largest gas off-road race in the World” and send in those entries while there is still time!
