Fast-action fun in a model that flips!

Kids aged 9+ can enjoy twice the fun with this LEGO(R) TechnicTM App-Controlled Transformation Vehicle 42140 set. In a first for LEGO Technic sets, this vehicle toy flips over when it drives into a wall to reveal the second vehicle. No wall? No problem! Kids can turn the model over to switch vehicles. On one side is an aerodynamic tracked racer. On the other side is a tracked exploration vehicle. With suspension, a cockpit, and tracks on both vehicles, plus a truck bed on the exploration truck, there's lots for kids to discover.

Take control with the app
Kids will love using the CONTROL+ app to operate their vehicle. Using the app, they can steer the vehicle and complete fun challenges. The app experience changes for each vehicle and cleverly switches screens when the model flips.

A great introduction to engineering
LEGO Technic buildable models feature realistic movement and mechanisms, making them a top gift idea for any LEGO builder who is interested in engineering.
