I couldn’t find a public source.  When I receive the plans I COULD be bribed to make a copy...

It was published in Flying Models October 1997.

Interesting airplane.  The 1997 FM article was by Fred Carnes.  He resurrected Atom design by Art Pawloski in 1956 and was a classic I-beam stunt.  Pawloski flew the design for four years.  Won Senior Stunt at the 57 and 58 Nationals the Walker Cup in 1958.  Fox .35.  From the table in the article.  Span is 50 in,   area 532 sq in, weight is 38 oz. 

Fred Carmes did an amazing job on researching the Detroit I Beams.  This artical on the Atom is just a small portion of the work he did.  Bob Hunt is to be commended for publishing all of Fred's work on the I Beam models from the Detroit area in a multi-month series in Flying Models.
