*@Daniel Goldberg* Yes, great, how many curved rail elements did you ultimately need for the spiral? In addition, of course, there is the question of how long it took you and for what there is no Lego train in this video? In any case, I'm curious how it goes from here, so I'll leave a like and a subscription 😉 In addition, of course, the bell is activated so that I don't miss anything when one of your next experiments starts. What do you think of my Leogzug videos? Well two are only there but there will be more to come. I'm looking forward to your extensive support.
