Thanks again folks. Yes liberal coats of future are used to make sure the decals don't lift. That being said, it still can be decal brand specific - i've had plenty of trouble with other decals lifting in the past. I usually test on a spare decal first, or use very low tack masking tape over the decaled areas.
I'll post some pics of the underside tomorrow, as the build is nearing completion now, despite some challenging hurdles...
The upper wing didn't want to fit properly; initially the inter-plane struts seemed to be too long, which threw the top wing out of whack. The "W" cabane struts were around 2mm short of their mounting holes. In this scale, I rig before adding the top wing, which meat that when it all didn't come together, I had to do most of the work again. So, I think there's either an issue with the angle of attack that the lower wings are mounted, an issue with the kit inter-plane struts, or the "W" cabane struts (or possibly a little bit of everything), or I am just a poor builder (the latter is most likely!). The inter-plane struts are all the same length in the kit - to get the correct stagger I think one set needs to be a little longer than the others, but if you do that, with the lower wings at the angle of attack the kit has you put them, then that reveals some issues with the "W" cabane struts - either the locating holes or strut lengths are off to get it all to sit at the correct stagger, and angle of attack, relative to that lower wing. As I wanted to keep this OOB, I didn't scratch build new struts or modify them other than trying to trim the kit parts until I got it all to fit - and by fit I mean go together with all points touching their mounting holes with the wings level and at the same angle of attack. The upper wing still doesn't sit right, it's all too far aft (and thus all of the struts are at the wrong forward / aft angles), but the wings are level so it will do... it's only really noticeable when viewed from side on.
In any case, should hopefully finish this one in the 'morrow.
Cheers,
BC
