Wouter,

I'm actually not sure. I received them from VectorWorks Marine and they are the fully white stock. But yes, touche' to Matt for quickly identifying (and correcting) the problem. It wasn't apparent to me that they had delaminatated as it occurred at the seam within the rudder housing.... I guess I would have needed to exchange rudders with another F16 to rule out rudders.

Now I can focus on finding the "groove"! Yippee.
