" How do you do a wind tunnel test on a model which flys at grams per acre loading?
A hard sneeze would wreck these models. "
.
Make the wing shape from titanium... wingloading has no meaning in a tunnel.
And then get a buncha us old farts yapping away at each other to provide the wind....
One of the locals (old fart, continual *****er) complained to me about the Cub he was trying to fly...
11 inch chord, c.g. at 4-1/4"...or in engineering terms, 38%... and he said it was "tail heavy"...
Goodness who woulda thunk it?
Talks up as if he knows it all, but in practice....
