Chris,
I read the site you mention, there seems to be some confusion (to me) also. The profile Peacemaker is sized between the Flite Streak and Flite Streak Jr. It has a bit smaller aspect ratio.
The full fuselage Peacemaker as published in MAN is MUCH different than the Top Flite kit. Someone on the Barton site mentioned that.
Actually, the Top Flite kits of the Flite Streak series, although quite successful (I've built my share), did not follow the way George Aldrich designed them. For that reason, George re-designed them for John Brodak when Brodak got rights to sell the kit. As a matter of fact, George would not put his name on them unless they represented his original designs.
George Aldrich liked to fly his planes slow to emulate flight of a full-size plane. I noticed on the Barton site that some were putting modern .29-.35's on the full-fuselage versions, saying that the Ollie didn't have enough power. Well, it has provided many folks with a lot of fun with less power. Whan GMA said to use a .25-.29 glow, that was a 1960 .25-.29, not a modern schnuerle.
Someone mentioned using a 9x6 prop (perhaps they meant on the Profile version). I think the full-fuse version might fly better on a 9x4 or 10x4.
I have a full-fuse version partly built. I got the kit at a swap meet and the wing was partly built, and the kit was missing the fuselage formers for the molded fuselage. I built the plans fuselage for it. The parts fit for the wing was terrible. Whomever started it should have replaced some parts. I set the whole project aside for awhile (several years).
