Do not use the flaps on the maiden or even the early flights. The Problem is while yes they allow the airplane to fly slightly slower, they also will cause a much sharper stall departure when it does occur and lolling around at this very slow speed just on top of departure during an approach or worse just flying around very low can be quite fatal.

Generally the fellows will experiance less safe approachs with flaps than without and its quite the opposite than what most folks have been led to beleve.
