OK so, learning the lessons from last time: all top-wing installations were re- (and some re-re-) done:
This time after painting the canopy-frames, which are OK (not really accurate for the SOC, but at least with similar "look-and-feel"), and whose very nice (IMHO) custom-chopped windshields, unfortunately, will in the end wind up all but completely hidden by the upper wings.
The top-wing installations, though finally successful, remained difficult right to the end. The problem is that the outboard "N"-struts simply MUST be absolutely perfect in length. Absolutely. PERFECT. Because once their installation has begun, there is just no way (at least, not with any of the skills/tools I possess) to adjust/tweak them.
The tiny fuselage struts - so miniscule they are at the limit of what my tweezers can even grip - proved (the hard way) to require attachment first to the fuselage, as seen at lower-left. Their tips are then free to spread outward as needed, when pressed-down upon by the top wing - until its pre-positioned outboard struts just contact the lower wing. Do yourself a favor and use brass PE - as opposed to the stiffer/harder stainless steel - and don't worry if (just as seen here) the fuselage strut-pattern is not quite accurate: their (more or less correct) height is far more critical. And in any case, they will also end up next-to-invisible, under the top wing.
In person (way more forgiving than these camera-closeups) their appearance has already "popped", to look like little gems. Soon to be yet further enhanced by touchup-painting, and the addition of (at least some) tiny decals.
However first I have to correct a major flaw, just noticed: the main pontoons are too long, and should terminate just before the tail - not all the way back under the rudder. Fortunately, their extra-strength PE attachments should allow for chopping/grinding of their back ends, in-place. Anyway, you know I am going to give it a try...
