You have to be kiddin... i fly in the Grand Canyon and when the winds pick up during the Spring it's like a Bull Ride which then makes quite a few people show you what they had for breakfast and the night before.
They are no different than fixed wing... if the wind is there and turbulant you are going to feel it sooner or later.
Weirdest thing though, some people will hold it down for the entire trip until just about the last 5' from touching down and in smooth air then volcano while holding the nice little white bag in the opposite direction to their new found skill of PROJECTILE VOMIT.
Yep, you guessed it... i have been through this more than once
Hope this helped.
