Maths is all very well, but empirical evidence, ie looking at what happens to anything it hovers near, would suggest that it has considerably more downdraft, at least in Merlin guise than a seaking. I certainly would not want to be under it. Anyway, in my book of maths, small rotor disc and far greater weight add up to more wind.?
