The Ansmann Racing 1:10 Master Smacker is the latest development of its notorious predecessor. The power transmisiion takes place via a smooth-running prop system. The spur gear is completely encased in a hard plastic covering that protects the drivetrain from unwanted impacts. The upper chassis plate with a green anodised design gives the entire chassis the required torsional strength. It's simply even better suited than its predecessor for rough, rocky off-road terrain. The front & rear axles are each equipped with a smooth running differential gear. Both differentials are designed as high quality bevel differentials. The actual drivetrain is positioned exactly in the centre of the chassis. The entire chassis layout is set up in such a way that the chassis balance arounf the diagonal & longitudinal axis is completely neutral. The model uses both batteries & saddle packs.
