I have a partner, this is his third homebuilt, he has all the tools, know-how and got me hooked on it. He is 74 and his jobs are to de-burr and distract visitors. I do the other tasks. Since there is no 51% rule on this plane, we don't pay any attention to our hours, we just put the date in the instructions. We complete a page per day, a casual, but steady pace. We started in January 2009 and should be flying in June, 2010, which includes about 8 weeks of waiting for new kits to arrive and an average of four visitors daily. The quality of this kit is outstanding, every hour spent working on it has been enjoyable.
