Narrative:

I was giving dual to a new student in an extra 300. Decided not to do much acrobatics. Planned on doing more GA instructing. The student did all the flying to the fly-in airport. I took over the flying when in the traffic pattern. Parachutes were worn and student properly briefed. Announced on unicom our intentions to do a couple of high speed passes. Did the first one without incident. The second one was the same with the high speed approach and a 45 degree pull-up. After leaving 1500 ft AGL, half rolled to an inverted climb. Then half rolled to upright. Then left the area. After talking to an acrobatic expert the aerobatic maneuver may have started on the steep pull-up at the field elevation. It was unintentional.
