First, begin by folding your your graph paper in half (excluding three boxes on the perforated side). Once the paper has been folded appropriately, make two marks--12 full boxes apart (allow for a further box back behind the airframe). Use a ruler to make a straight line with the length of 12 boxes directly up 1 row of boxes from the two marks you just made. Then make the stabilizers, spars and counterweight as shown. To avoid confusion, one line you will cut along has been omitted from the photograph.

After the fuselage is made, take another sheet of paper that is folded in half along the lines of boxes. Mark out the wing as shown (1 box of constant chord at the root; a leading edge sweep of 1 box of chord decaying every 3 boxes outward from the constant chord box; and a trailing edge sweep of 1 box of decay along the 4 boxes of wingspan). This will complete the wings.

Solid lines indicate places to cut . Dotted lines indicate fold lines.

Note: 1 box = 0.25 inches
