Update 2.
I have started to tissue the lower skin.

This process is very slow, I don't want to mess it up.
While that dries I have begun the tiresome process of fitting the string trailing edge to the upper wing.

I have been trying to put a slight crescent shape in each rib bay rather than have the trailing edge taught, this has slowed the process down some what.
Once I have the wings done it will be time to figure out how I will go about making the surfaces moveable. I currently have an idea for the rudder and wing warp (they moved together) but I can see the elevator being a problem
