Thanks mate, are you gonna build this bird? It's bucket loads of fun
A little progress...
The manual calls to install "shear webs" on the aft edge of the spars... which I didn't understand

so I hope this is what they meant
Look for anything protruding from any surface (like spars at the wingtip, and shear webs at the spars) and carefully sand flush
Cut and glue some cap strips for the ribs...
And now, the part I was affraid of... shaping the leading edge [&:]
So... we glue the leading edge to the wing...
And sand it with coarse sandpaper to conform to the shape of the wing. It was time consuming, but easy after all
Stay tunned!
