Hi, I am building a 4o size twin trainer called a Gemini from plans. Its fairly big with a 70" wing and around 900 sq. inches. The plans call for nylon wing mounting bolts. I am wondering if this would be stronger than a 1/4 ply piece going across the fuselage with the typical blind nuts. It would probably be easier to mount but I am not concerned about that. Any thoughts?? Below is a pic of the plane and the mounting parts that is on the plans.
