I've just read this......Wonder how it could work with our models?

A similar thing was tried about 10 years ago on a large scale Fox Keith. The lower wing skin was flexible and using a bar on a cam the wingsection near the root could be changed from under cambered to semi symmetrical.

Think the model was built by Wild Skies

Ah, so it has been tried in model form. Interesting. It’s a kind of wing warping isn’t it.

They say there is nothing new under the sun. Ha! :lol:

Was tried wwwaaayyy before that Bill, in the 30s (maybe even before!)

And for Planes, I believe in the 20s :)

I think at the time, everything has been tried. That's without talking about the wing warping ones. :)

In relatively more recent years, you have something like the HKS-1 glider. No ailerons, flexible wing :) That one is from the 50s if I remember.
And a few more that went from expendable wings, to variable in flight dihedral etc that the Germans, and others, tried in the 30s :)
