ADA's are next to useless on next gen, Feels like its 4WD definitely feels off, it can barely drive, bounces unless your going like 90 in 3rd or 4th Gear, Constant bouncing,Feels like it only has 3 tires regardless on which terrain your on.
More Info :- Drove a olga and this runs fine, not tried the Sarka or Gunter/Truck though.
