(...) Tobbe, The current version I have has 2 motors but it is not strong enough to twist the structure left or right. I do like the gear system you have on yours and maybe it is a question of insufficient torque to twist it around so I may have to (...)

(...) Sure - it took about 6 weeks from start to finish to build the excavator, although I wasn't working on it all the time. Much of this was spend "debugging" and tweaking the model rather than pure creation as such; in that way it was a bit like (...) (25 years ago, 14-Nov-00, to lugnet.technic)
