Hi George @georgeswork!
What a nice entry! This is a superb scheme of a superb plane!
Regarding the wing, to my knowledge, “6-3” wing had no slats, just a fillet above, not present in the slatted version.
Your kit, as well as the real thing, have the slatted wing, so you should be (you are!) spot-on!
By the way, I think the “6-3” wing was a tad longer too…
So, I believe Hobbycraft instructions need(ed) some revision!
This will be a spectacular build in this great Allan’s @kalamazoo GB!
Waiting for your progress!
