As I said, there's a lot that needs to go right here and not all of it did. Small gaps everywhere and these were filled with card. Also, I just wasn't able to get the wing root fairing consistently aligned with the fuselage. One side stuck out and the other is an inzie.
Thanks all. Several passes of filling and sanding have occurred now and I think I'm at the point where I'll move on.
As is often the case, I tend to work backwards. The wheel well sides open to an echo chamber and should actually have some closing ribs on the sides. Of course, I can't let this go and I should have done something about it before gluing the wing halves together. So now, I'm adding the ribs arthroscopically. Here's the first of 4 in place after having fished it out of the innards of the model twice.
Thanks gentlemen. All 4 ribs are now installed. Reference pics on the net show what appears to be some kind of electrical junction box on the starboard inner rib.
So me being me, I set about adding this detail thrown together with card and lead wire:
After painting and highlighting:
I'm a bit disappointed that AM omitted the big retraction jacks so these are something else that I'll now want to scratch up.
