Here's my first attempt at making a fully functional backhoe loader, with motorized functions controlled remotely using two SBricks and pneumatic functions controlled remotely using a wired external pneumatic remote, something I've been inspired to try by Jennifer Clark's models. All in all, the model has 9 motors in it (and 2 more in the remote) and 6 pneumatic circuits.
