I gave a person on another forum a ground effect aircraft I designed as a Beta Builder. To put the wings on, they needed to use a "jig" I supplied, just two right sided triangles. I gave such detailed diagrams, they came back (I can't build it I don't understand". I showed the model to another person, and they thought I oversimplified it. You'll have better luck than me, I believe this person just wanted the model to take up space on their hard drive. It's never appeared, so hopefully that person deleted it, like I requested.
With the jig, if placed in font of a fab, (set up with baffles to channel the air properly), like an external wind tunnel, with the nosed tie just underneath the front, the model would lift into ground effect. Thus ended my effort. It worked for me.
