I'm in systems training right now. What others have said is precisely correct. The 170 is an incredibly simple airplane to learn (there, I said it), and the training program is designed to feed you everything you need to know.

Do study the material the company sends you prior to training. Make flashcards of all the limitations and memory items. It will reduce your mental workload once you get to class. For your own sanity, don't try to know how to build this airplane before you ever walk in the door. It's not necessary.
