Correx-PSS: L39HawkF-18FoxxU-2ImpalaA-10SpitfireF4USeaFuryP-51VulcanFW190-free plans!

Howzit fellow Slope Addicts !!!

About a year ago, I was fortunate enough to have a two year job assignment to move my family from Michigan USA to Port Elizabeth South Africa. I met a great bunch of local “okes” who introduced me ( or infected me ) to the fine world of slope flying. There are two local slopes here in PE, the Maitlands and the Lady Slipper. Although the guys fly all sorts of stuff here, there is almost an addictive attraction to the Correx Mig. The okes started a Mig blog and then later started a thread here on RCGroups. We got together a few months ago and had a group build for another batch of Mig’s. It was this event that also got me hooked ( or infected yet again ) on building with Correx.

I have a few ideas bouncing around in my head, so I thought I would start this thread for my forthcoming PSS Correx builds, as well as offer up a place for others to post their “Corro-Scale” builds, plans and techniques.

The CorroScale Plans - free

pdf's for plotting, each plan has two sheets, be sure to plot 1:1 scale

Please ensure your local Print Shop does not "plot-to-fit"
the pdf files should be plotted at 100percent size or 1:1 or full scale, whatever their plotter software is set up to call it.
You can print a small set of plans on A3 or even A4 paper, but the proper build plans will only fit on A0 paper.

A0 paper is 1189 x 841mm or 46.8 x 33.1 inch
ANSI E paper is 1118 x 864mm or 34 × 44 inch ( I havnt been back to the USA, so havnt yet plotted these plans on E size )

autocad zip files also available for anyone to use

CorroStang

My current project is the CorroStang, the other Correx P-51 free plans available are just a bit to “boxy” for my taste, so I am working on my own set of autocad plans with some of the scale techniques borrowed from the Dave West’s Mig Plans. It’s a bit of trial and error, with some general outlines drawn, then cutting some correx. I didn’t like the first fuzz I cut, the nose was shaped wrong and the tail didn’t look right either so I started again ( Correx is quick to build and cheap). This is the second fuzz, I am also building this CorroStang with Correx formers. My Mig (as with most Mig’s here in PE) used ply formers, but I want to see if the Correx formers will hold up to the abuse of the local slopes

pleasure, steeg

if you want to start right away, I would recommend the Mig for sure, its a proven design. the plans for the Mig are drawn for a motor mount, so they need to be altered a bit, but its easy to do.

thanks guys, the research to find more info is something I enjoy,
and I have a few more corro warbird ideas floating aroung in my head.

Sketching in autocad is pretty easy for me at this simple level, just import a scale image and "trace" lines around the wing, rudder, and elevator. The hard part is getting the fuzz correct, as I havnt figured out how to accurately predict how a flat sheet of correx will "bend" in three dimensions, after the inside flutes are cut.
