Tom, I think the key is the use of polyurethene glue. It has a sticky texture and by inserting long straight pins at an angle with the balsa and foam, I did not need to weigh down the husks nor even use them at all. I put the 84 by 3 inch strip on the top first and even with the dihederal of the AT wing, there was no gaps in the sheeting. Surprised the heck out of me. Thanks DAVE.
