In the months preceding the release of new Technic models it is usual that some curious minds try to decipher the most hidden secrets about their mechanics.
And one of the most intriguing aspects related to the new 42054 Class Xerion 5000 TRAC VC, is the control of its steering modes combination (2WS, 4WS and Crab Steering).
We have seen it working at some videos from the model unveiling at recent Toy Fairs, but there was too few clues on how this was designed except there is a stick to switch modes when moved into three existing side-by-side slots.
Barman (barebos) made a guess exercise to find which mechanism could be in the heart of this Xerion, that's responsible to control the advanced steering modes. He came up with some amazing stuff and presented it to us in a cool video.
In a few months we will have the opportunity to see how accurate his guess was .
