I have the magazine, plans and started a fuselage about 15 years ago! :-D
Mr. Hoag was a YMCA director, and he modeled the plane after an all red F-86D. Wesley Smith from Delaware was very keen on this plane and we corresponded about it for a long time after we met at the '93 NATS.
Everything Keith says is true, but he left out the part of the large asymmetry in the wings, similar to the *Original* Nobler. I would use a LA 46, maybe a ST 456, or a Aero Tiger 36 in it. (of course a really high tech 40 wouldn't hurt! )
