I've made a start. It's all a bit experimental, so let's see if this works...
I wanted to have a go at making a wing first as this, to me, seems like it could be the most difficult thing to get right.
Having scaled the drawing to very approximately 1:72 I took the sheet of 80 thou. plasticard that I used for making the airfield office on my diorama...
...and then made cuts in it...
I then took a sheet of 10 thou. plasticard and cut a sliver off it. The sliver was cut into lengths and fixed on using M.E.K. solvent to represent the ribs.
The ribs were trimmed and the leading and trailing edges of the wing sanded down. The corners were also sanded.
And then a coat of paint applied, just so I can see how it looks.
The ribs look rather prominent but no more than on some old Airfix kits. I may have another go but if I do I will have to buy some strip, instead of cutting a sliver of 10 thou. plasticard as one length isn't enough to do one wing and cutting a second sliver to the same exact width is almost impossible.
