The 80 MODELS is the top of the range in the engineering series and it is the most advanced one. It is brings together a broad range of themes and features some very impressive models. The "supercars" theme includes 4 amazing vehicles, a formula one car, an off-roader, a trailer and a combine harvester. The "cranes" theme includes 4 fully functional cranes, a construction crane, a rotating lever crane, a lift and a loader. The "mobile cranes" theme takes modelling to extreme levels and includes several types of forklifts. Many of these models can easily be modified to become operable with the bonus 3V engino geared motor and children can use their imagination to discover ways to optimise such modifications. The motor has a double-action switch and works with 2 AA batteries (not included). The set contains detailed instructions for 12 models and a motorized dinobot, an amazing huge contraption that works with a crank action to move the mouth and the tail of the dinosaur. Instructions for other models can be dowloaded from the engino´s website. The package is suitable for 6-14+ year old advanced builders.
