Novarossi has presented the new high performance Mephisto.21 for 1/8 scale off-road. This engine uses a square stroke power plant with a 4-port design to supply a linear power output and to keep fuel consumption low. A new R4/18 conrod is also presented, redesigned and made with a special aluminum alloy that allows it to have a high resistance while maintaining the lightness and performance of the previous R4/17.
