Sometimes, although mostly not, it is a good thing to second guess the designer. I read what I could and spoke to whom I could while building. I found Hans who flies at Kilcoy incredibly helpful. Net result was I changed a few things whilst building. I have the divorced brackets for the elevator. I also used streamlined tube for the struts, a Savannah style tailplane/elevator instead of the inverted aero foil one and I have bolted rather than riveted the bracket for the cables on the rudder and the bottom plate to fuselage on the nose leg. Hans told me, from experience, that those rivets will work loose. It is a known problem with the standard 701 tail that the nose can drop in the flare. Everyone, including Zenith recommend fitting vortex generators on the elevator to solve this. With the Savannah style tail this is not a problem. Again, Hans has this style of tail. I really don’t know what I would have thought of the aeroplane built 100% by the book as it were, but I was interested in building and flying, not stuffing around changing things afterwards. I am very happy with the aeroplane as it now is. I think listening to people who have built and flown for a lot of hours ( not me, I only have about 100hrs on mine!) is well worth while and certainly worked for me. The 701 was the very first all metal two seat ultralight design and was originally powered with two cylinder Rotax two stroke and hence was designed as light as physically possible. Things have evolved a lot since then and some things are worth changing. I also have additional L angle diagonals on the fuselage sides to cut down oil-canning (also a known problem) and wish I had put them on the top and bottom also since it still rattles like an old tin can when I get down to 50kts on approach. Sorry for the verbosity but hope this is helpful!
