62L,
Was this the S-7S you saw? Friend of Marks I've not met, but nice plane!


Regarding build cost, mine is somewhat an unconventional story, so not representative of typical. PM me for more details.
But essentially, you are looking at about $21K for an airframe kit, $24K for motor and FWF package, then add paint, instruments and any custom stuff to that. So, a basic plane could be built for between $48K and 52K. Find a started kit (like I did - wings already built, 18K!) and a used motor (you find them now an then w/ 200-500hrs for 14-15K) and you can save some time/cash. You can also look for a built one, but they are few and far between - people don't really like to part with them. Mark Pringle will also build you and ELSA model - not sure on the cost, but probably approaching the $90K's.
Build is as straightforward as any. I know a guy who has the divers experience of building kit Supercubs, composites, Highlanders and S7's. He says the S7 goes together about as fast/simply as you can get, and a LOT faster/simpler than the Supecub.com kit. Anyone with patience, persistence, and basic mechanical skill can do it. I think patience and persistence are perhaps the most important, not some hard skill.
I love the building experience. I restored an S7 before this one. If you have the time to do it, its fantastic. I only worked on composite planes before this, and I loved that, but fabric and the basic assembly/minimal metal stuff you do with this (drilling, trimming, riveting) is great too. B
Bottom line, if you like to make stuff, and like airplanes (assume that's the case), you will like building. Again, patience, persistence and free time.
If you are honest with yourself and have the time and persistence to put in a few good 3hr nights a week, and a least a full weekend or two each month - things move along. It will still be a 12mo plus project though. More likely 2yr. But its amazing how fast 2 years can zoom by when you are having fun.
Thanks for the comments on the panel. It is not the stock panel, I drew it in CAD and had it CNC cut. I have the file for anyone building an S7. Also a slightly smaller carbon fiber version is now being made by Joel Milloway in ID (full S7 build/service center - and a effing guru on the S7), along with the mating glare shield. Big improvement over stock.

I am hoping there will be no fewer than 4 S-7S at the BCP fly in this year, including that yellow one and Mark's. He's the dealer so I am sure between him, me and others - test rides will not be an issue!
