I do not know where the feeling comes from that a B4 performs like a B2. Maybe the older pre 2004 models with the smaller compressor, but we have one of those operating EMS hot and high that took over from a b2 and she out performs the B2 by quite a bit. Despite the higher payload due to the increased max all up weight, she laughs at 58ooft 42 degrees at a B2.(No crit on the B2) Yes, she is not a B3+ butthen what does compare to a B3+? Wait till next year when the B4 is rumoured to come with a Arriel 2D engine-even more horses.
As far as the skids go. We had to get used to not having a reference ie the Squirrel skids, as you can not see them as clearly from the seat as the Squirrels. Had no problems during auto's etc once we got used to the new reference.
