Default GP Illusion info needed

Does anybody have a sketch about wing and stab geometry for the GP Illusion
Also wing and stab airfoils copies or PDF and I will put this into CAD to create my owm set of wings/stabs?

Thanks

Arturo,

I have a partially assembled Great Planes Illusion kit at home. However, I don't think I can help you out much because my kit has sheeted foam wings and the tip blocks have already been installed and sanded to shape. I will look through the instructions when I get home tonight and see if I can find anything to help you.

Arturo,

hope this might help. The picture is the best I can do as I don't have the plan of sorts. What's interesting is that the wing and stab relationship is such that the wing top and stab bottom touch the fuse thrust line. This was one of the the main differences between the Tiporare and the Illusion. Another was the reduced dihedral on the stab and the increased wing area from 720 to 750 squares.

You could probably scale this photo to obtain the planforms and airfoils with the understanding that accuracy would be questionable.

David.

Thanks David,

This info is perfect. I can draw something in CAD and check the dimensions on the fuse.

Hi, I'm also keenly interested in building an Illusion. If anybody has plans and could part with them for a week, I would be happy to pay shipping both ways if you could roll them up in a tube and lend them to me temporarily (send me a PM). I promise to baby them and return them in the same condition.

If allowed, I'd be happy to post high-quality high resolution scans of it afterwards for everyone to use, as long as there are no legal objections.

Interesting idea but there is no such thing.

The Illusion is strictly a glass and foam kit and plans for a wood build never existed. Of course, one could take the plans for a Tiporare and without too many modifications, end up with an Illusion.

Just so you know Don just made a mold of my fuse. I also sent the "Plans" along with it. I think he will be making cores as well:
