Nose ring to LE is 10", hinge line to hinge line is only 14" . It will be classic legal so I don't want to move numbers around. I hope to build to min weight to maxamize its flying given such a long nose and short tail numbers. 700" wing area.

During the late 80's early 90's a lot of Pampa planes were built with 3/32 sheet for the fuse sides. They had to use a lot of formers to get a ridged body.Most had one thing in common is they looked like boxes. I used 1/8 and even 3/16 on most of my planes. The reason for the 3/16 is I can find very very light 3/16 and I then can sand the body into a oval shape very easy with out adding extra stringers where the body meets the top block. These models built this way came out lighter and stronger than the 3/32 jobs.

The issue, of course, is to produce a structurally stiff unit. I've built planes from molded 1/16" balsa from nose to tail that were very rigid, but they were molded with many formers. The thinner the sides, the more formers it takes, generally.

These days, I tend to use 1/8" "C" grain sides from matched sheets. Cuts down on unintentional twists and warps.

I've not used anything but 3/32 for fuse' sides since the early '90's.  I have two Crosswinds with over 500 flights each, one with soft mounts and one with maple beam mounts and they're both still in good shape.  The one I pancaked inverted at this year's nats is back in one piece with little effort, ready for finish.
All fuse' parts are molded with 6lb balsa, both are TP based areodynamically, and both use PA 65 or 75, whichever I'm in the mood for at the time.  Both weighed 61 to 63 oz.  (Note: I only used 1/32 ply for doublers, just enough hardwood to hardwood joint for the motor mounts.  We all tend to overbuild.  I do glass the nose back to the wing le.)
My old Sierra was molded balsa fuse with light 3/32, weighed 62 oz and, as far as I know, is still flying down Nashville way.  It's on it's second fuse' as I also managed to pancake it inverted.  Hmmmmmmmmmmmm???  What gives here?

Thanks Guys for the Ideas. I think the build article stated the weight at 62 or 64 oz. powered by a KB45(not sure how much they weigh)and veco extension(3/4") all tailfeathers are shown solid balsa . 1/2" on Elavator and 1/4" on rudder. I plan on using built up units to save weight. Airfoil is quite thick for its vintage. Tri Gear a nd swept tail. Elevator and stab are a little on the high side in relation to wing , was thinking of putting in a little positive incidence at front of Horz. stab. Thoughts? I have been waiting for years to build this plane and will start cutting wood in a couple of weeks .
