It is ashamed that LEGO did not have official monster trucks, but as a consolation, it does have its own monster trucks of sort of its own and a pretty extreme one at that. Meet the LEGO Technic 42099 4X4 X-treme Off-Roader, a super cool looking LEGO Technic truck that fits the bill of a monster truck. It packs 958 pieces which includes an advanced Smart Hub with 3 motors that drives it.

Control is via your smartphone using the LEGO Technic Control+ app. With it, you can do what you expect from a RC vehicle, including drive forward, reverse, steer, accelerate, brake and climb over obstacles. In addition, the app also provides you with real-time feedback, such as the speed and tilt log, lets you test your skill in challenges to secure achievement badges and play cool sound effects.
