Do a search for this. Someone else shows a pic of one, and mentions a 1993 Hobby Shack catalogue.
I have an EZ Mystic 30 ARF, which is similar, but different colors and graphics. About 48" span. These were designed by the Austrian champ, Hanno Prettner.

Construction is typical EZ type, which you can still find on certain ARF's today.

Let me know if you find any info on the Mystic 30, as I need to know the balance point for mine. Thanks!
