Even though my son is only 9 he had built up the truck in a few hours. However, non-functional. The transmission of control is quite tricky. Hence the Papa could ran and had fun!
Particularly impressed micht in the model, the differential for the rear axle. Together with the large Lego Technic Backhoe we now have all the pieces together to create all possible own self-built, well-controlled Fehr, companion. :-)
