Here is the completed and temporarily assembled structure posing in the cold snow [:'(]. I am having a problem with the rubberbands being too tight across the wing. The size of the bands I believe are #57, but I need bigger. I have been told that these are the typical size used for holding on the wing but I have been fooled [:@]. There is no way these rubberbands can be used. What is the larger size up from these bands? What is the correct size in rubberbands used for wings?
