You guys mean a Mystic like this...
Getting there... just a little more work but little time lately. This is the E-Mystic (4s, ~750W), there is also a G-Mystic (OS 32 SX and #300 Hatori pipe) in the works but needs a little more
hand cranking before its read for finishing. Electronics are fortunately all lined up - 5000 series Spektrum servos on the tail and Hobbico digital CS-110's on the ailerons.
But these are just 30's. The pursuit for a real Hanno '93 WC Mystic 60 plan is something that I would also very much like to see in the flesh. If Hanno only were to be able to share these plans with his fans for posterity and the good of all mankind (well, maybe that's a stretch...

). The Calypso plan is something that I have began working on since I have an almost complete built up model. The design of the Calypso is perhaps one of the simplest models I have ever come across. A joy to build and it will be fun to one day finish up those plans.
John, I seem to recall that you were going to do some extrapolating from a Model Tech ARC that you had if I'm not mistaken. The kit built is a little simpler than the ARC but the lines are the same - just no foam on the fuse. A simple box with cross grain sheeting all down the top with a pair of turtle decks built atop. I have posted a bunch of photo of the Calypso build here and on RCG. BTW, it wasn't me, unfortunately, who got to spend time with Mr. Prettner. It's our friend Michael who says he lives not far from Hanno.
Michael, please keep me in the loop if you happen to come across a set of original Mystic plans from the master himself. I have been known to do extreme things for treasures like that...
I almost forgot, one of the extreme things I've done was to procure a NIB Hanno Special. Received it just a few days ago...

'tis a Mark I intact with Hatori header and pipe (well, the red pipe is branded by OS but it's really made by Hatori). That engine is reserved for an M60 that will be built the day plans are something we can work from.
David.
