One thing that I had not originally expected in the kit, was that it would have leading edge flaps in addition to the trailing edge flaps.

These can be seen in the pic below. I have never used leading edge flaps (or even slats / slots) on a model before, but from the responses I got to a question about these flaps (which I posted on here a while ago) it seems will be an interesting exercise to figure out just how much of what to use.
