ok, now I'm working on the rear hull part. for once I think pics are self-explaining
still a WIP, hope to complete it tomorrow...
I chose this "sandwich" structure for a matter of building easiness. there's only one flaw (at least!): the curved upper layer is thin (only one card sheet), so when you glue it you should pay attention not to press it too hard or to put too much glue, because the paper could bend and take the shape of the framework beneath. in this case there's no possibility to double the layer thickness: the final result wouldn't be a regular surface... maybe it's not perfectly clear now, but you'll get my point with next updates.
