Is a Shadow microlight, with its wings folded, a butterfly or a moth?
You know. When buttterflies rest, they hold their wings vertically. On the other hand, moths spread their wings out wide.
I guess that a Shadow is more of a butterfly, because its wings are vertical when at rest.
I built my own wing-fold system and fitted it to my restored Shadow B-D a few months ago. I like it, because I can easily rig and de-rig solo. The large-tyred castor wheels allow me to push the de-rigged aircraft across the loose gravel surface to/from the hangar.
