I own a hardcopy of this plan, although the various planforms are arranged differently, resulting in an unusually sized plan that is 60" long by 24" high. It was published in RC Sportsman, and although the plan says March 1976 (under DeLuca's name), this is probably the date that the designer finalized the plan, as the actual date of publication was October of 1976.

Thanks. Got it, have added that to the datafile now.

I would like to elaborate a little bit on this design. It might be easy for pattern plane lovers to dismiss this one as rather ungainly and inconsequential. After all it is smallish .40 sized, and has the mostly unloved “fish profiled” fuse look that became popular in Europe in the late ‘60s and early ‘70s (this one looks like a mackerel or wahoo in side view). Also, not designed by a “big name” pattern flyer from way back when. However, I find certain aspects of this design fascinating. Notice how DeLuca drooped the nose down (sailplane style) in relation to the aft portion of the fuselage in order to lower the engine and bring the thrust-line center in line with the wing AND the stab centers. In fact, the whole thing is constructed using that same datum line, so achieving straight and true construction, and correct incidences, should be easy (see construction notes). Also, notice how the wing’s belly pan is constructed utilizing a 3/8” balsa “fin” down the center with shaped blocks on each side, and then narrows rather quickly halfway down the wing to leave just the “fin” (Dorsal fin?), which then extends all the way back down the rear fuse (and flows into) the rudder. Pics of a completed model reveal that it is handsome design if finished correctly. (Steve: I sent an e-mail with a link to an RCG thread that has a couple of nice photos, so you can post them in Oz and the source properly credited). The owner of the one in said pics claims it is a great flyer. I might have to build one to find out.

The Olympia Jr. In the photos belonged to a modeler named Curtis Mees, he always spoke highly of the model. He also enlarged a set of plans to have a .60 sized version he called the "Olympia Sr" which he finished in the same scheme as above.

I've got an older "blue print" of the plans. The print has faded over the years. Thanks for the scan.
