Not wanting to steal Jon's thunder but a quick search on my laptop delivered this... Skymaster 60.pdf

It's a good thing I backed up my RC main repository some time back. It is temporarily down (fried system hard drive).

While they are of the more modern and recent SM design (per Chuck's photos), it could probably be adapted with a little CAD work to have a SE setup and pipe under the wing - much like a Citation.

I'm not sure but I believe that Dominik in Germany might have an original SM60 kit with the plans desired. But that's speculating a bit.
