No thats the schools 170C, but they also have a 170D. The panels are the same though (or pretty damn close too). Theres not too much noticable difference in between them, not enough really to actively notice it in flight anyway but if I had to choose between the two Id choose to fly the 170D, I think its the nicer of the two, but they could just be the difference between two aeroplanes, not necessarily because one is a different model. You are right though, the D model has a longer nose and no large ventral fin.
