Siku set of crawler excavators 6741 and 6717. The remote control and rechargeable batteries are approved for use in the model; batteries are not included. The new Bluetooth-controlled crawler excavator can be operated not only with the special Bluetooth controller (6717) but also via a mobile app, and it is now equipped with a sound module. The Bluetooth RC model, made of metal and plastic, weighs over 2 kg.

The Siku Control 6741 crawler excavator features a total of six electronically proportional high-performance gears that move this monumental RC vehicle safely and precisely to its destination. The right and left sides of the crawler chassis can be controlled proportionally and individually to maneuver the excavator accurately to the desired location. The upper structure can rotate endlessly 360 degrees, as it operates wirelessly on a slip ring carrier.

The question of where the front of the excavator is when the upper structure is rotated multiple times during focused digging is not always easy to answer. Here, the electronics come into play. With the push of a button, the upper structure is returned to its normal position. This means: wherever the excavator arm is pointing is the front. The excavator arm is controlled proportionally by three gears and is capable of digging realistically, even below ground level. Thus, it is possible to excavate holes.
