Because the Skyship 600 is a type-certified aircraft and as such the banner attachment points on the envelope cannot be modified from the type design without a tremendous investment of time and money, as well as FAA involvement. They want to see compliancy proven for everything before issuing an approval to modify the original manufacturer's drawings. As the guy who designed the banners and did much of the labor in assembling them, it was my duty to make the artwork as large and readable as possible. The helium vent is an unavoidable area. I will be sending AMS some vinyl to cover up the missing part of the N and the tiny portion of the black lower-case A on the REVOLution side. That's the best that can be done without a full decal job, which, admittedly would be far superior, but is hardly ever considered without a multi-month lease as minimum.
