Great Video!

The small cameras show many what only one saw before. Knowledge is spread.

The stall as shown seems to be gradual from the trailing edge, for approximately the inboard 1/3 of the wing, then zips out to the tip.

Is that visual stall, what you actually feel yourself?

That is, can you feel and can you control, holding just short of the complete stall, that matches the visual stall?

I will try again, can you see the "drop" with the tuffs as you feel it?

yes, you can feel it and see it at the same time.

Great job!
 
Thanks for a very good video! It was very useful seeing how good that wing is in real life.
Great idea with the full flap stall too. (The -7 video)
If you are to do more tests; any chance that you can do one with t/o flaps on the -7?

Once again: thanks for the effort! Job well done!
