Hope you'll sort out the alignment issue, my friend @pikofix.

Thanks for the tips @tcinla - yes, the Camel has a unique wing setup, and probably that’s what is causing this in the jig. The upper wing clicks into the fuselage struts, but the outer struts seems to be short. The anhedral can explain it, and I could actually see this on the wing when I looked at the model from sideways. I think you are right, I need to start with the fuselage struts and then get the outer ones into their correct positions, maybe by using a tape or rubber band until the glue sets. I don’t like using CA glue on biplanes, because I am afraid of misaligning the wings. CA sets quite quickly and I like to have a little bit of time to get the correct setup. That’s why I keep using good old Tamiya extra thin cement and a jig. Maybe I make my own life too complicated… 🙂

Well, it seems this is going to be one those models with a build error, sitting in the corner of the cabinet.
I managed to glue the wings in place, but the result looks weird, and I think I figured out why - of course after the glue has dried.

Eduard’s Ferocious Camel

According to this article, I was not the only one experiencing problems with the wing assembly. The upper wing was straight on the Camels, and thats why I tried using the assembly jig. I remembered from the descriptions that the upper wing was made straight, so the manufacturing process was simpler. I followed the Eduard instructions, and I indeed had to force the upper wing to an ahedral, and also a slight twist. It seems that if I swapped the outer struts, the problem would be solved. Too bad that everything is dried and set by now and I can’t verify whether this is a real problem or I had other construction issues. I ordered a few things for rigging and other general modelling stuff, since I am running low on flexible threads. The build is on hold for a few days, and I will continue from here. I will post photos later to show the weirdness of the wing assembly.

I am really close to being done with project, for good.
I compared the assembled model with the drawing and the wing alignment was so bad, that it left me with two choices. Either admit my mistakes, declare the model FUBAR, walk to the trash bin and forget about this otherwise awesome kit, or try to salvage it somehow.
So, I tried to save it. Carefully removed the upper wing, and tried to reset the struts. Unfortunately I snapped three of them in the process, and really messed up the joints, loosing the possibility of a decent, clean rigging later. At this point I was again very close declaring it FUBAR, but made the quick decision of trying to glue it together anyway, without stripping the paint on the wings and making new joints from metal wire - or possibly new struts from my Evergreen stash.

So this is the best result I can get - the wing still sits 1-2 mm too close to the front of the fuselage. You might see it on the misaligned front struts on the fuselage - these should be perpendicular to the horizontal axis, but on my model they lean forward a few degrees.
Probably that was the root cause of the problem as well - I really struggled to find a good reference point for the upper wing alignment, and now I can see that I should have used the front fuselage struts for that purpose.

Now I wait for the rigging supplies to arrive, finish this nightmare somehow, and hide it in the display cabinet’s dark corner of shame.

Or do like Mr. Miyagi in Karate Kid, finish it, smash it, and start again. Although my Camel will never be so perfect as his cars were in the movie.

Indeed a wise decision to not trash this build, Csaba @pikofix
Nobody will notice those minor issues, only if you tell them.
