gm all, purchased 2 sets so that i can make the original model and a more extended one.
Looking back in this thread i guess some more counterweight might be of good use to start with .. so i was thinking of modifying the original counterweight plates by removing (saw / dremel) the middle part, glue them together on top of a non modified plate, fill the empty middle with some real weight (iron / lead tbd) and see how it all balances out.. and off course longer beams , slower movement etc -- i guess some programming using pybricks etc
