I have 3 new in the box ssc kits made by Wayne Voyles who was chief designer at Lanier RC for many years. I dont remember the name of the kit off the top of my head but can look tonight or tomorrow evening if you are interested? Our club flew ssc for a year or two some years back and I had purchased several of Wayne's kits which fly great btw. They are foam wing designed with a hardwood spar and we flew them with .15 Magnum 2 strokes. I think they can use up to a 40 2 stroke if I recall correctly(?) but that would be way overkill I think. We had lots of fun with these !!
Let me know if you're interested.
John
