Have flown? both the Bell 412 and Puma sim. Both make a crashing noise followed by the black screen of death. The reset takes between 5-30 sec depending on what emergency caused the crash. Graphics are pretty good although trees tend to turn to face you which is a little strange. Managed to get my NHP to scream once after attempting a 4 point roll in the 412, it really didn't like being inverted.
