Codeen, not sure how much of this thread you have taken the time to read.
It does take a bit of weeding to get to the good stuff, and the non repetitive stuff. This thread spawned detailed discussion about EC-135 and its fuel system (in the EC-135 thread) and a passionate discussion about autorotation, loss of power in singles and twins, low and high inertia heads, and much else related to controlling NR and flying the bird to the ground successfully when one is unpowered.
