Scott,

Ralph Beck did a set of drawings for the Curtis Robin if you can find a set. It was span in the 80 inch range and I think showed both versions of the Robin. These plans are what I would term as 'super scale', I think the original Proctor Jenny kit was based on his drawings and if you have seen those plans you have an idea of what I mean.

I don't know if anyone still sells those drawings but if interested you might put an ad here and RCScaleBuilder and ask if anyone has them.
