This modern tank trailer was built according to the latest findings in regards to safety measures. “TOPAS” stands for “Tank vehicle with optimal passive and active safety installations”. These include: ABS, low gravity-center, high-positioned break lights and chassis protection built in aerodynamic shape. The tank has elliptic double wedge shape and for weight reasons is built of light metals. In the future, because of their highly inflammable payload, most tank trailers will be built in similar shape. Length of the built model: 430mm For the completion or color design of this model kit are suggested colors by the manufacturer which you will find below under my product recommendations.
