Hippolite:
Right! For clarity:
#1 was the ground test vehicle, now retired (the FSI sim has its nose!)
#2 is the first flight vehicle. Was equipped with -6 engines and an electric start system. Neither were chosen for production, now #2 is retired, used as a ground test rig
#3 was the workhorse for FAA cert, still doing duty daily on the latest certification features. It will finish the deice cert in a few weeks.
#4 is now the VH-92 demonstrator, the "Wildcat" with the increased cabin length and the back door. It is doing VH-92 risk reduction work at West Palm (look for some press announcements about the stuff it is doing).
#5 is a prototype at West Palm, doing additional Risk Reduction work for the VH-92.
