With the Technic Hovercraft LEGO Building Set, you can race over land, water, mud and ice, as no terrain is too hostile for this highly realistic model. The set comes with 170 pieces that are easy to handle and form both a hovercraft and an airplane. Both models in this LEGO toy feature a cool racing design, spinning rotor blades and moving engine pistons. While the model will provide hours of fun, it's also a good way to introduce your children to the dynamics of a combustion engine. It has sturdy construction and can hold up to rough use and some drops. It's definitely possible for your child to use the toy outside.
