FlightpathOBN, First, this discussion is way above my pay grade and so my stance is, "I'm learning". I did the experiment out of interest, not to "prove" anything. That said, I wonder if you haven't misunderstood just a bit what I'm thinking? By "load" I simply meant resistance to a force, in this case the lift axis. It doesn't matter that such load increases/decreases with weight etc, which encompasses your point. I was responding to your "no load on the airfoil" point - there is "load" in the form of resistance to the lift generated, and of course it will be different for different cases. Is "load" not indistinguishable from weight & Nz?
Cheers!
