The Lego Technic Batmobile Tumbler (42239) recreates the iconic vehicle from the Dark Knight Trilogy as a remote-controlled model spanning over 12 inches in length across 719 pieces. Controlled through the CONTROL+ app, builders can operate the steering, toggle the lights, and trigger a jet engine boost function that lights up and adds a burst of speed, mirroring the cinematic version of the vehicle. A built-in rechargeable battery powers the model via USB-C, keeping the action going without the need for disposable cells. The set is aimed at Batman fans aged 12 and up who want a hands-on build that doubles as a functional RC car rather than a static display piece. Digital building instructions are available through the Lego Builder app, offering 3D zoom and rotation to guide builders through the construction process.
