Ok here is the deal. . . .I have to come clean right off. it's not really free plans it's more like free foam cutting patterns and a three view but that's all you need to build this plane.
It's based on a four inch wide fuselage so you can build it with 2 inch blue foam.
A half sheet 4' X 4' is enough to make one plane. A whole sheet of 2 inch blue foam (4' X 8' ) runs about $26.

My model took 4 oz. of ballast in the nose just behind the gunner.
with the wing incidence set at zero at the root the stab needs 2.5 to 3 degrees of nose down to fly level. E-flight 480's provide more than enough power to fly the model and only pull 20 amps. this makes a three cell 2100 MAH pack useable.
the wing span to my model is from tip to tip 53 inches. The wing cores were cut to the point that the tips start to curve ( top View). This does not correspond to the three views .
In other words I cheated a little. After seeing how the model flies the scale layout will work just fine ( 48 inch tip to tip) so stick to it. My next one will.
