Hammered in the FS forums. Seems like a wait and see if the developer acts on the issues. I hope the Starship in development (different developer), exceeds expectations.

The main problem....is no one reads the documents enclosed.
Initial issues was. Some people expected the 2100 version. This was not to be Bill was specific this is a futuristic 2200 with advanced avionics, and updated power source to correct shortcomings of the 2100.
Take a moment and search for test pilots notes..you will see that in testing the Lear Fan was not stable. It vibrated because of the dual engine mated to a heavy rather unreliable transmission. Bill accounted for this and tried correcting it in this version.
I am sure updates will come in due time.
