I never said not to build it because the airfoil is too thin. I didn't make any comments about how it would fly, or suggest that it needs to be thicker. All I was relating is that the wing span makes the plane sound larger then it really is.

I don't know where you're getting that I was saying anything bad about the design, but you clearly missed my point. This kind of thing is the reason I don't post more often. Far too often people try to misinterpret what's being said and turn everything into some kind of debate.
Gee Andrew, nice sidestep, I do not think I mininterpretted anything you said and I did not write that you were "saying anything bad about the design". But here is what you wrote about the airfoil thickness:
"But the airfoil is thin... about 1" thick..."
"My point isn't that the airfoil is dated, but rather that it's much thinner then say a normal Flite Streak, or a Twister, etc. The span seems a bit much, but it's a thinner wing then most that size."
Indeed, you did not say not to build this design, but you did suggest that for some reason that the airfoil was thin when it is not thin by any normal standard. Whatever your reasons were about discussing this airfoil as too thin is not based on reality and could be misread by a casual observer.
I was not criticising you for whatever your observations are regarding the wingspan being somehow unsuitable for whatever engine some might recommend to use for this model. I will admit that I do not understand your comment that "The span seems a bit much but it's a thinner wing than most that size". So, the airfoil is really not all that thin. And the span works out to be about 48 inches. How is that span a "bit much"? How is it "a thinner wing than most that size"? Are you talking about airfoil thickness here which is in the context of what you previously wrote or are you talking about its aspect ratio? The aspect ratio of this Peacemaker is roughly 4.5 which is definitely not on the high aspect ratio scale for our CL stunt models.
It was not my intent to turn this into a debate. All I have been doing is reading what you wrote and trying to put it into perspective. Regarding the Peacemaker, the airfoil is not thin. There is a good bit of area in that 48 inch wing with an aspect ratio of 4.5 which would be a wing with something around 500 square inches of area. A good .15 might be anough. A diesel 15 would be enough as shown by George Aldrich. A modern 25 like a Brodak or OS LA or Enya would be a good fit for that area.
