Hi Amram,

I had #2 and was quite happy with it, but it isn't a "slowflyer" as in "slow", it needs a lot of ground speed (relative to its size) to be flown precisely. And no wind whatsoever, at a TOW of 600g. I finished by selling mine and investing in some batteries for my 2m ship.
A friend of mine has the Quiet Storm, no noticeable differences except for design, wing surface and control throws. Both models fly about the same.

Regards,
