TalkTurn, Good observation.
You are completely right! DA was at about 17,300 and TAS was something like 70 KTAS when at 50 KIAS, but I tried different airspeeds below that and it seemed that anything less than that would only start me down.
Actually now that I remember I was laughing about it with the photographer, I found the spot where ANY change in my Power, Attitude, Airspeed or the slightest down draft would make the helicopter start down vigorously, it was at its absolut limit, felt like hanging by a very thin thread, funny feeling to not be able to climb an inch more.
Wonder what the autorotation caracteristics would be at that altitude, I guess it would have pretty much the same qualities of a flying red brick.
