RE: DA-50 vs ZDZ 50 NG?
My very first gasser was a ZDZ50NG, once you figure out what they like they start very easy, has the best transition and midrange of any engine. Still have it, gave the plane and engineto Tom, it' his all time favorite to fly, it's the plane in my avitar. Primarily fly DLs now for obvious reasons, definately the best power, hasexcellent transition anda good midrange when tuned properly. Nothing wrong with a DA, if it isn't reliable, even I can't beat their service.
