oh well, the 900 is a great plane, just keep in mind that the wing fuel pumps does not "pumps" but "sucks"
and the ventral tank is not an "active tank" but just a big can to bring extra fuel to be transferred, and you have limitation on that.
Keep yourself focused on the Collins ProLine 21 avionics because it is not so intuitive, but once you are into the system it's great.
if you have any question, just ask
p.s. don't be surprised by the wing antiice system...it is a litte bit funny
