Carl,
Drawings up at my area in the Vendors Corner.

DOC,
At 200 squares the TD may be a little weak, I can't really say for sure. I do know that an 061 is too much engine for the Ringmaster 150.

A Tee Dee will easily pull a 200 sq.in plane if under 11 ounces.

Another data point:  Barry Baxter's 1/2A Stuka had 223.5 square inches with a 37-1/4" wingspan and a Medallion .049. Full fuse, no flaps. Said it was 10 to 11 ounces. Claimed to be a terrific flyer.

Hi Pat, in my experience; 201sq" wing area would be far too small for a 1.0cc model engine. I have an Akromaster(250sq"s)
that is powered by an MP-Jet 1.0cc diesel, that fly's beautifully on 45' lines.  At 11 ounces ready to fly sans fuel, it doesn't
need flaps, which would hinder the turn radius.  The modern glow 1.0cc(.061cu"s) could easily pull a 300sq" model.

Barry Baxter built and flew His "Half Arrow"(250sq") and a "Wee Duper Zilch" (240sq") both fantastic performing models,
that were powered by a Paw.049TBR diesel.  H^^ :)
