I have used the SS 633 setup for over a year--carbon to aluminum. I take the bolts out maybe every three months to switch a wing etc. I see zero evidence of any corrosion of any kind. I use grease on the bolts and foil in fresh water almost daily from April through October.

Not doubting anyone's understanding of chemistry; simply reporting my experience.

The flat mounted wings don't seem to have the problems which the socket mounts do. The rear wing on my slingshot showed barely any while I had to take the front off with a rubber mallet.

A titanium fuselage with a kryptonite mast seems like the obvious cure.

That scares the hell out of me.
