A mate of mine took me up for a flip in his microlight. Didn't enjoy it, as he didn't bother telling me that he was about to do a turn (what felt like 90 degrees, but was probably a sedate 20).
A couple of years later visited my brother in Botswana, and he had arranged some nights in a camp - you fly there and back: fly in was ok as first thing in the morning, but the afternoon flight back was turbulent to the point that I felt quite green, despite being in the right hand seat. I decided that it might be a bit like driving versus being driven: one I don't feel a thing, the other I'm a nervous wreck and can also feel the effects of motion sickness.
So far, I've been right. Haven't felt sick at all, in 45 hours odd, some smooth air, some bumpy. The only thing I still don't really like is stall practise (but I blame a previous instructor who took lesson time as his play time).
