I'd reconsider Eaglesoft's CJ1...I haven't found any other decent CJs (which are different from Bravos and Is and IVs...especially in the avionics stack...) besides the eaglesoft, and it is a REALLY great package. I know it isn't a CJ3, but it's the closest you're going to get...
The only strange thing about it is that you have to load the airplane in the 2D
panel or it will lock up FS
...not sure why, but it does that.
The panel is wonderful, the model and flight dynamics are accurate (I have flown the real CJ1...it is VERY close) and its just a sweet little airplane to have in your fleet.
