In regards to the comment about learning more about the R22/44, while that may be true, I found a vast majority of the topics covered at the safety course to be generic to any rotorcraft. Most of the ways people kill (or hurt) themselves in Robinsons are not exclusive.
Actually, one of my after action comments was that I thought I'd learn more about the R44 and its systems (i.e. Bell 206 Initial).
I found it to be an excellent safety refresher. Not just a R44 lesson.
