What specifically are you having trouble with? (scaling, cutting, gluing, something else?)
I can try to help out with things I worked out during my build
I found a lot of useful information in the pep forum, mainly the Stickies but also the threads about other peoples builds. I'd also suggest, if you haven't already, building some simpler models just to get a feel for it... the Recon model I used had some really troublesome folds that might have prevented me from finishing if I hadn't built a few others first.
