what is the stall speed for that thing? Can't be much slower than 180.

Those wings sure did flex a lot! Imagine that plane heavy and in a storm.
That's why they flex. So they don't break off.
You need to do a bit of studying on heavy jets. No company takes a brand new, untested aircraft up on a first flight and approaches anything like normal cruise speed. I would be surprised if they retracted the gear.

I was on a 747 flying through some rough weather once. The wings were flapping like an eagle that just picked up a salmon.
The wing flex on the 787 seemed a bit out of the ordinary considering the stripped down condition of the aircraft. You don't see that on other boeing craft so it must have something to do with teh plastic.

In theory, a "light weight" heavy aircraft actually will exhibit MORE wing flex than a "heavy" one.
I don't have the technical background to explain it in simple terms but the concept is similar to a heavy sea vessel in rough water versus a light one. The heavy vessels structure is more stable. Physics was never my strong suit, ugh!
Boeing has alot of momentum riding on the 787.
