hey I could use some help from some of you golden oldie kit builders.I really like old byron kits and I am building a pitts.I have gotten to the wings and I have been advised by several people but each of them has a different opinion imagine that!I believe that byron on this kit recommended just sanding the foam wing and covering.Some say no I have to "skin the wings with balsa" others say fiberglassing is best.still yet one said mix elmers and water cover and sand.I dont want the weight to become a factor but I do want it to fly and look nice.help! all advice appreciated
