Although my N17 project is a long way from completion, I concur with both above. Mine is taking much longer than it should. But I knew it would before I started. The main reasons are that I do have another life and my wife and I like to go off several weekends a year and on other adventures. Also, I have changed nearly every area of the kit from "as designed" to something that I feel looks a little more original. When you make one change, you have likely made ten and you have to figure out all to continue. Before everyone goes nuts over that statement, I have conferred with Robert on nearly every change - all that are structural.
The AA kits are definitely builders kits and require a lot of interpretation of the very basic drawings that are the plans. But as said above, Robert is a saint about answering questions and helping decipher some aspect of the build. Also, there are many other builders out there who are a wealth of info.
