Agree with keeping landing area in sight. I teach on the 47 and demonstrate an auto backing up, if you do wish to transition to forward flight to finish the full down auto I have found not to push the cyclic forward to much, this has a tendancy to unload the head slightly, thus losing RPM. You can then bring the 47 to a zero forward speed auto. I must admit took me a while and a lot of practice before I tried a zero speed auto. Just nice to know you can land it in tighter spots if the donkey stops...
