Has anyone tried using boron for outlines on the super light models such as AROG and 35 cm? I've been doing some experiments, and it seems viable, and much more durable than, say, .015 sq balsa, but I don't have a scale that can give me any idea of the weight penalty. Surely I'm not the first person to think of this, so there must be a reason it's not the common practice. Someone care to educate me?
Good flying,
Joshua
