Nieuport 17 Upper Wing Cutout Question

[Widmerpool]

I'm putting together a Nieuport 17 with the fabric center section of the top wing cutout.  Eduard's instructions indicate only that Y-shaped support be placed in this cutout area.  I suspect that what's actually needed inside the cutout is something a bit more elaborate -- apparently four or six stringers also in the cutout joining and running perpendicular to the "Y-bar" support. 

I wonder if any Nieuport experts can set me staright on this, or better yet, provide a diagram of how this should look.
Also, I believe that this cutout was probably covered with a piece of cellon or other clear material.  Any ideas on whether this clear material was regularly removed and the cutout simply left open?  It seems any transparent material would get dirty quite quickly and the temptation to simply remove it would be be pretty great, assuming this wouldn't overly affect flight performance.

Many thanks for any guidance.


Best,

On the covered uncovered issue, I have the windsock datafile and theres a few shots of the cellon covered but not one of it removed.

+1.

IMHO removing the cellon would expose the wood ribs and spar to the elements, that's probably why they were left in their place. Don't know if it was possible to take them out.

Widmerpool, I'm of the same mind as Zabu in that they probably didn't leave
the space open.  I would think the transparent panel would have to be changed
quite often.

Thanks very much to all of you for your help.  Looks like I'll be adding a couple of spars and putting a piece of clear plastic over the cutout....
