Following up on the Zorex-220 PF-excavator, I found that there were some things that could be improved. Inspired by the colour-scheme of the USA-based Link-Belt Excavators, I started designing a new excavator. Allthough the principles and scale are basically the same as the Zorex, there are many differences: * Link Belt is based on a real existing machine, Zorex is just a typical excavator* Link Belt has fully studless chassis, completely hiding the drivetrain inside the chassis, while maintaining the suspension* Improved driving and slewing thanks to a roller.* Uses L-motor for slewing* Openable cabin-door, cabin-roof, superstructure-side-doors and opening top.* More detailed interior* Greebles mimicing the insides of the machine* Improved scaling by extending boom and tracks Link Belt & SBrick Some weeks before Lego World 2014, I was contacted by the Sbrick-team, asking if I would like to demonstrate the Sbrick at Lego World. They sent me the Sbricks and this excavator was chosen to be the test-model for there prototype-Sbricks. The tests at Lego World turned out succesfull, the model and the Bluetooth-controlled Sbricks performed well. Using an iPod Touch as controller, there was no interference with the many PF-controlled models there. Ans the Sbrick-system allows you to controll the speed of the motors, making the controll very precise and more realistic. So when I started making instructions, 2 versions had to be made: 1 for the PF-version and 1 for the SBrick-version.
