I just can?t imagine how a proper repair might be made!!
I assume you have a copy of the plans to work with. Take a close look at the
plans and how all the skin and spar cap plies tie everything together right
at the the point of breakage. The place you will be doing the repair is the
point of greatest stress in the entire canard. You need every bit of that
strength and there just isn?t any way to get it back without negatively
affecting weight or airfoil shape.
I agree... best to make a new canard. In the end, you will have a structure
you can have confidence in and there is no price you can put on that.
