I know this post is very old, but for the benefit of those just getting started, AS&S has already demonstrated to me that they are on top of things.
The guys working the front counter are super helpful and will print out a complete estimate for the whole airplane chapter by chapter so that you can see what you need. It was more than I had expected.
I purchased the Cozy MK IV Plans and am very happy with the call. AS&S called me on the phone after reading one of my mosts in an online forum to follow up, answer a question, and make sure that I had gotten everything.
If you have a question about the airfame build cost... call them and ask for an estimate on all of the chapter kits. You can be sure that there will be more to buy, but you will at least have a good estimate to start from.
Kind Regards,
