FG MONSTER TRUCK: 4WD, WB535, RTR, Yellow Body The 4WD Monster models WB535 were improved in some details visually as well as technically. We extended the wheelbase to 535mm. For a maintenance friendly rc installation we widened the chassis. Further improvements were made at dampers and the rear brake. Powder-coated aluminium parts care for the visual upgrading. According to the extended wheelbase handling and further driving characteristics were essentially improved. FG Monster models are the perfect choice for every occasion and for all surfaces - asphalt, grass or even loamy ground.
