I'm seriously considering wing warping. Wing with a normal amount of bending stiffness, but very little torsional stiffness.
Conventional wings have bending frequency much lower than torsional. Mine won't, so some of the conventional flutter assumptions won't work well.
I can avoid divergence if the shear centre is in front of the 1/4 chord. I'm fairly sure of that.
For flutter, normal wings avoid flutter up to 'infinite' speed if the cg is in front of the 1/4 chord. But I suspect that I need my CG in front of the 1/4 chord and also in front of the shear centre?
