0.5 flight time, 4 times around the pattern. All wheel landings. On 4th roll out, held the tail up, and ~1500 rpm kept it up. Practiced tail up along the runway to the 2nd turn off. Big temperature inversion - 55F at the surface, 75 at 1000 AGL. Wind 090 at 7 to start. 100 @ 9 at the end. But that was on the gauge. Didn't look or feel that much on the runway. Logged just about 100 hours of "airplane project" time since it was certified. Of that just under 20 was in the air. I'm optimistic that with some longer flights, the ratio of total time to flight time will change.
