Glad I’m not the only one who hd to fight the Roden Camel (though in my case I was responsible for some of the battles). I too found that the upper wing wanted to wiggle a lot: the struts are thin and a bit flexible. With such cases I find that structural bracing wires (i.e. mounted in the wings, not flexible like EZ-line) helps considerably. Stretching wires symmetrically (one left, then the corresponding on the right etc) makes it easier not to cause warping on the process.
The problem i found was the fuselage to wing struts, the locating pins needed to be at an angle so they engaged with the holes, roden have them in line with the strut so they never sit in the hole properly. This means as you're trying to get them in place the slightest movement and it all moves making a positive placement extremely difficult, if i build another one i think i'd file them flat and add my own pins to aid alignemnt.
I've been plodding on with this camel build and it's now rigged which brings it a step closer to completion. I still need to rig the undercarriage section but the horizontal bar broke on me (just one more problem i've had with this model (it's still shedding paint)) The wheels and rear skid are drying so once they're ready that's pretty much it for this little PITA. Since taking these pics i've done a few touch-ups so i should have this build rapped up in the next couple of days
