It's possible I'm not remembering correctly. I thought we had both DA-20 models (I know we had the C1), but either way we called them Katanas. Diamond may have changed the name after we sent them back, too...
You called it a C model before... could be the 1 denotes the change. It might have also been early models that didn't yet have all the improvements.
I do really like cessnas, but the modular design for the diamonds is pretty impressive. Something I'm not fond of is that the 20s can't be IFR certified because they don't have the wire mesh in the wing like the 40's do (to conduct electricity if there is a lightning strike.
We'd pull the wings at 1000 hrs, getting lots of comments from passersby. Yep, they are VFR, though there was quite a bit of instrument training (simulated) still going on in 'em. They're fun to fly, fast, and don't use a lot of gas. Heck, it'd be a great little
two seat cross country bird... if you could only fly in weather it'd be even better. We also had really good service out of the
Continental IO-240, going well over TBO before pulling the mills. Even then, the pull was more of a cautionary thing. We stayed in touch with Teledyne and sent in oil samples on a regular basis as they wanted data on this relatively new engine.
I liked it. Very reliable and packed a pretty good punch.
