"Even a full motion simulator is hard to hover"
I have tried three different 206 FTD's (sims without motion) and found all a challenge to hover compared tyo the real deal. Shawn Coyle has pointed out that hovering is made more difficult by the absence of certain "vertical" cues, and I think that this may be the problem with these sims. As one approaches to hover height, the detail (texture) of ground objects begins to blur on the visual diaplay, and the hovering goes to hell.
