Plans

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.

developments:
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.
Notice:
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.
