All about this set

Experience the amazing power and acceleration of this high-speed LEGO® Technic 42072 WHACK! model, featuring a lime-green, red and gray color scheme with racing stickers, sturdy front bumper, large rear spoiler and wide black rims with low profile tires. This advanced building set is equipped with a pull-back motor and a new-for-December-2017 engine pop-out function, which is activated on impact. Combine with the 42073 BASH! pull-back model for extended play possibilities or to create the WHACK! ‘N’ BASH! combi model.

Great for children's first introduction to LEGO Technic. Not too complicated to assemble (some supervision is needed to avoid frustration if a single component is assembled incorrectly), and the result is excellent. The assembled car is robust, aggressive, and fast thanks to the spring mechanism. When purchased together with the "companion" product, it also allows for the creation of an even more beautiful model, while the individual models are very fun for head-to-head battles in which the floating component jumps in the air.
