Glad to see you're willing to give it a try, Peter! Yes, the Fokker D.VII in any scale is one of the easiest builds, along with it's stable mate, the Fokker Dr.I. Both have almost no rigging and what little there is is quite easy. Next in ease of build would be the Albatros and Pfalz scouts. A bit more rigging, but nothing too overwhelming for a newbie. Surprisingly, the Hansa Brandenburg W.12 is another fairly easy build, in spite of the floats. It also has very little rigging, but you might want to take this on as a second build. I look forward to seeing what you decide upon. The best way to get advise and apply it to your work is to post a build log and ask questions along the way. You will amaze yourself by how well you do.
Cheers,
Bud
