John,
On that note. There was 2 H9 Suks at my field yesterday. One had the 3W80 twin and the other ZDZ80 single. The ZDZ sounded and was so noticably nicer and smoother sounding that I though it was the DA100 before I asked the guy. I'm sure setup had all to do with it. The other comment I have is it flew some much lighter to my eye than the 3W. I was just watching. Both guys are locals and I'm sure I'll see both planes again at the field. Just an oberservation but I would buy a ZDZ 80 S or one used in a plane ect. anytime! No wonder you have improved the way you have John, that combination looks like one of my electics in the air.!~)
