Sorry, scale WOULD be helpful. I only work in 1/48 (but how would you know that !!)
Here's a drawing of what I had in mind. The 'ropes' would have to be stiff enough to support the model and yet thin enough to look to scale, don't know of a way to do that.
The only other option would be to mount it to a backdrop of some kind.
Displaying a dirigible is a little different than a airplane !!
Excuse the drawing. I consider myself to be a bit of an artist when building and painting a model. Can't draw for sh** though.
