Wow! You guys are rough on the guy!!
I have done backwards autos in the old H-13, Bell 47 and had a blast doing them. Takes a little work on the pedals, and you have to be intuitive about the airspeed, because there isn't any indication of same. But the autos work out just fine! I would never do them in a less forgiving helo (read that as any other helo) because the Bell 47 is a very very sweet machine in the auto.
