Main model from LEGO Technic set 42037 - Formula Off-Roader doesn't resemble formula at all so I tried to build something closer to formula out of its parts. Since it has huge wheels I call my alternative model "Off-road Formula". It features steering, independent suspension and V4 engine. I began building it more than one year ago and got stuck with front axle. It was the most difficult part of whole model because I had very limited sort of parts. Building instructions will be available at buildinst.cz/en soon.
