I’m just getting started with technic and recently built 42110 Land Rover. I ordered it immediately after I saw that I could learn a bit about how transmissions and differentials work. I plan to get the other “ultimate” sets but am realizing there are other facets of mechanical knowledge to be had - other types of movement than just standard automobiles, like the complex construction equipment movements and their features. For instance, I am very interested in 8455 Backhoe Loader for its functions and especially the pneumatics. I’d love to see other inspiring usage of pneumatics and different/varied technic functions.
I know grohl666 has recommended 42040 fire plane for its technic functions and design. I’ve seen 42043 Arocs recommended for its more modern pneumatics (v2?).
To gain a better variety of technic functions I wanted to get opinions on what else I should look at. What are the sets I should look at for learning varying and interesting technic functions?
