Thanks for the comments all. Life has got in the way of this one for me, and I've been putting what little time i have for RC into other ideas / projects. I have revised the plans for Adams / Dollar Tree board and made a few other tweaks following my partial build. Turtle decks still need to be added to the v1.1 plans - but i would say that they are pretty simple if you look at the pictures of my first build and are familiar with the general FT way of doing things. The rear fuse is essentially a tapered rectangle trimmed to fit the rear cockpit bulkhead former. The nose one is a the same design as the original FT spitfire - a rectangle with a tapered rectangle cut to form the sloping nose. Cockpit will plant onto the hatch.
I would say that there is an issue with the positions of the braces that the hatch sits on and slots down into which made fitting electronics tricky which will be another thing to address in future revisions.
Need to see if the thing flies first of course !
