Personally having been flying FS since 1998 and seeing and owning most of the addon aircraft, I have always found CS aircraft to be very well made. Yes it took a long time to get the FMS figured out, but up till this aircraft they never made one, and it is a very good one to boot.
CS's expertise has been in the models up till now, and I am thrilled that they took it upon themselves to learn something new for us.
I would love to see the 767-200 and 400 modelled since we already have the 300.
