Downwind Quickstops

Hi All

Why are downwind quickstops dangerous? I know not to do them because of Vortex / SWP but when I try to use my rusty Principles-of-Flight to work out why I'm getting confused.

When INTO wind: I've got the lever down and I'm flaring. As the machine slows I begin to pull in power.
At this point I've got Power Applied with Low Airspeed and because the disc is tilted backward (but the machine is still moving forward) I have a rate of descent ?

If I'm DOWNWIND, because the disc is tilted backwards the wind behind me would help lift ???

What have I got wrong ?


While I'm here why does it take more power to hover downwind ? Must be some interaction with the tail ?

I can't find these answer in any of my (old and dusty) books.

Thanks, DtP
