Dominik,
Thanks for posting. I hope you don't mind me having suggested that Rune contact you.
Was it me who expressed interest I the SM40 plan copy? If not, it should have been.
A PDF scan would be easier to send than paper copies but either works for me. Without the vintage SM60 plan, the 40 size could be scaled up to build what would be a very close 60 Skymaster. I suspect the main difference between the two would be an airfoiled stab on the 60. That was typical for MK to go flat on the stabs in the 20 and 40 size versions.
By the way, the SM on the Korean site in BA trim colors is the vintage 40 size.
Rune, I hope you continue your quest for the 60 size version. The guy in Korea might be the best chance for a plan at this point.
Dominik, thanks again for offering us your plan.
David
