Cool design and nice model building.

So this one looks like it is designed for speed.
Is the root chord really 375mm? It looks smaller than that compared to the keyboard.

Flys nicely ! .........and looks good in the air.

I would like to know more about your technique for the positive molded fiberglass fuse. Your results are very good.

After shaping of the foam, I see that you have applied some sort of finish, possibly thin layers of tape. Can you describe this process a little bit more? Thanks.

If sense not Lost in Translation This packing tape layer is for simple excavation of foam (after I and fiberglassing the fuse).
