    Great you built it, and thanks for the feedback.
    With my model the lowering of the outtriggers was pretty smooth until they hit the surface. Then the slipping clutch became active quite fast. Maybe you fixed some gears too tight on the axle and brought too much friction into the gearbox.
    To your second question: The switch at the rear end controls the rotation of the upper carriage. So I slightly modified the superstructure and added a few parts to the lower part. Just have a look at the area around the turntable again...

    I've made the model with LDCAD and added steps for the building process.

    When you import the model into you should see the steps on the right side of the program. Therefore you should be able to step through the building of the model. For more information please look here and in the manual within the application.

    I hope this helps. Sorry for not providing a pdf instruction - I don't have the time for this at the moment.

    You're right. The gear bearings are a great weak point of the model. But I was running out of ideas how they could be improved.

    You are right, one motor for each track can be used easily. This is a common way to do and a lot of solutions/models are available. Even for the 42006 a ready-to-use model already existed.

    But I want to try out (and above all: understand) the working principle of a subtractor for driving and steering with its pros and cons. It was more a personal interest and challenge than a practical need.
