Beanie, your idea of slightly enlarging the wing beyond scale is an excellent one if you're after a stand off scale model that gives up a little fidelity in favour of flying. You'll want to enlarge the tail section over scale by the same amount as the wing and cheat maybe 1/2 as much on the tail moment as well. Even with those alterations it should still retain the pugish look nicely.

Your solid scale plan in the last post is way off scale in terms of fuselage cross section. The original has more of a round top trapezoid look to it. If you haven't googled on it yet do some searches on "grumman skyrocket" as well as the X5F designation. It should turn up a few extra drawings.

I seem to recall that I may have some very old control line scale plans for the Skyrocket in about the 45 inch span range. The construction will be crazy heavy as all good control line scale models were back in those days but the sections and outlines may provide you something to work with. Let me look around for them and I'll get back to this.
