THE FUNCTIONS
MK Constructor has made a video with the model functions. I had to work things out from an LDD-file with 196 missing pieces and no building steps. It was a great puzzle (but I like a challenge). I got everything working except the 2 speeds for the props. They work, but just at one speed.
Maybe I can do an upgrade someday…
