MD500 maneuvers with tailwind

[Jeast458]

Hi I just recently "upgraded" from a 44 to a 500C. I use it for cattle work and capture some deer with it. I've read bits and pieces about getting into a jam when maneuvering it downwind but not enough to fully understand how to avoid or recover from this jam. I think I felt it one day and it felt like the wind was going to flip the tail over my head , full aft cyclic was slow to help. Can anyone elaborate on this , I'd like to stay right side up. Any help is greatly appreciated.
