I trained at OBA with the cessna's, a year later I went back and flew around 30 hours in the liberty.
In my opinion it does not make an ideal trainer, I had no problems flying it, but had 150 hours TT at the time, and had done a few hours in the Diamond Katana, which I found had similar handling characteristics. I think it makes a nice VFR tourer,
But as a trainer, its too sensitive, too easy to be tempted to push the nose down when landing, thats where the problems start. The nose gear just can't take any abuse.
