## Description

Get ready for a colossal LEGO build and play experience with the 4,108-piece LEGO Technic Liebherr R 9800 Excavator. Developed in partnership with Liebherr, this replica model is operated via the intuitive LEGO TECHNIC CONTROL+ app and powered by 2 advanced Smart Hubs with 7 motors. The sophisticated app technology enables super-precise movement and amazing functionality, while delivering endless authentic digital play combinations via 4 different control screens with cool graphics. The Multi-function control screen enables users to drive the machine in all directions, rotate the superstructure, extend and raise the boom, open and tilt the bucket, play realistic sound effects and get real-time feedback, such as boom position, power usage and drive distance. With the One-touch screen, users can use drag patterns to control the boom, arm and bucket, while the Custom-built movements screen enables them to choose pre-set commands or record the model’s actions to create complex sequences of movements. And, with the Challenges & achievements screen, users can complete challenges to unlock reward badges.

The model’s complex gear mechanisms and technologies introduce LEGO builders to advanced elements of engineering while helping improve reaction times, cognitive thinking and creative problem-solving skills.

Review: Excelente modelo LEGO - Un producto de LEGO como ninguno. Su calidad es notable desde la caja en la que vienen todas las piezas. 6 kilogramos aproximadamente de pura calidad. El modelo en sí es altamente recomendable para constructores LEGO avanzados y/o para aquellos que buscan un reto. Por el precio que pagas, obtienes además de las piezas para el modelo, 2 Smart hubs, y motores que puedes utilizar para MOCs (te sugiero la app Buwizz). Armar el modelo es un reto, empiezas primero por la estructura con las orugas, después la estructura superior, luego el brazo y finalizas con los detalles súper minuciosos que son gratificantes cuando ves el resultado final. La app LEGO technic (sugiero veas compatibilidad en la página de lego) funciona al 100%. Conforme vayas armando el modelo, el instructivo te mostrará cómo realizar las pruebas durante el proceso de armado y concluyes con la calibración del mismo. La app tiene retos para entretenerte por lo que además de que se ve genial como trofeo en casa, tiene jugabilidad. El único contra que le pondría sería que para jugar el modelo ocupas de manera obligada tener la app en tu celular y que los Smart hubs tengan baterías (12 baterías AA), ya que de lo contrario el modelo no lo podrás cambiar de posición una vez lo hayas concluido. En conclusión: por lo que pagas obtienes un gran modelo, muchas piezas si te gusta armar MOCs, Smart hubs y motores.
