Finley is on target with this. If the Q1 driver built it then he knows what is underneath. I have not heard of this kind of damage of a PLANS built canard in 20 years of looking. But then, it would be helpful to actually see what the builder describes. If the Q1 driver HAS to know the cause he will have to open it up. I can't imagine how you would get spontaneously appearing dents from static storage. We have seen corrugations on top of the canard from lack of post curing however.
