and this is my case !

I found Zeppelin LZ32 plans (here)

It's huge: next to 200 meters in the real world, means 1,38 meters in 1:144 scale !

The technics of drowing of my other balloons (Caquot and Drachens) are useless.

How I can do it without using tons of material ? 3D print or lasercut ?
.... Why not both ! Here is the inner structure, it's easy to print on a 3D printer standard, or laser cut 3 mm

I hope you like it.
Now I'm printing the first pieces of the nose to test if it will be strong enough.

A lot of work still to be done: nacelles and the coverage.

You will find all the pieces of the model, free to download, here:

I'll keep you posted.
