Serpent have released more details on their new 1/8th nitro on-road chassis, the S977 Viper. The goal behind the newly designed vehicle is to have an easier to build, easier to maintain and easier to drive car. Many parts of the S977 saw refinements compared to the 966-TE and therefore the front end is now even more adjustable in terms of king pin angle, trailing or leading kingpin and even offset is adjustable with our compromising the overall strength. At the same time the rear was simplified with only one upright position and three shock mounting holes to make for easier setup. Also new is the rear brake system that found a new home at the rear differential to reduce the negative effects of the involved rotating masses. Incorporated into the design is also a very easy to adjust chassis flex option via a single screw as well as other refinements. The kit will hit the stores around March.
