So I was looking at those big motors in the radial series and I was thinking about building a 200% scout, but I was questioning the structural integrity of the big foamboard pieces after I saw josh putting an aluminum spar in it. Is the paper thicker on both sides? Does the foam end up compressing permanently at that thickness? Also, are reinforcements on the fuselage still necessary? I know they probably are on the wing, but I've seen videos of higher scale models having two layers of foamboard (meaning there is paper in the middle) almost all the way down the sides of the fuselage.
