You must want a hard copy, you probably saw this

I didn't! I was browsing for designs in the PAMPA collection of OT plans.
It does answer my biggest question: I wanted to verify that it was, indeed, a side-mounted engine. At this point I feel I could just build (well, after I get a
decent CLPA plane done).
The plans book has a drawing with symbolic dimensions (dimension 1, dimension 2, etc.), and a chart that you use to size your Easy to the engine size -- so you can build one from 1/2-A size all the way to a then-60-sized (now 45) 50" wingspan plane.
I just took a look at that article of the "Easy." Yes, I have that magazine.
I don't think the elevator is large at all, in fact, the easy is well proportioned. IMHO.
The elevator is a bit big for a flapped stunter, and way more than is necessary for a flapless -- take a look at a Sig Skyray 35 for an example of an elevator area that works just fine for flapless stunt. I'm expecting that if I use the original hinge line (which is necessary for it to be OT-legal) I'll take pains to hold the elevator throw to a minimum, ala modern Ringmaster practice.
Do you have the original 1949 article? Would you be willing to send me a scan?
