Exotek have introduced the F1 Ultra, the next evolution in their F1 line of chassis for the F103. Based on the hugely successful F1R, the F1ultra has been refined for the Tamiya F103 and benefits greatly from its wider track and shorter wheelbase and works equally well on foam or rubber tires. Features include link type rear pod for exceptional rear grip, optimized for use with 7.4v shorty packs, inline or laterally, for a more compact and lighter car and the bottom plate only design helps generate more steering response. This coupled with the increased rear traction creates an overall better handling car. A unicrank steering assembly gives smoother steering and a lower center of gravity at the nose to reduce traction roll.
