Today's flying lesson was.... short.
It was decided that we'd take up 03G for some more spin training. I did the pre-flight, we pushed the plane out, got in, and I started the checklist. Everything was cool so I asked for ground clearance and was told to taxi to runway 32 Right. (Hey, I'm doing my own radio work now!)
We arrived in the run up area and I did the pre-takeoff stuff. One of the final steps is the mag check. Switch off the left magneto and observe a 100 RPM drop on the engine. Flip it back on and see it return to normal. Repeat for the right magneto.
However, when I killed the left mag, we lost 400 RPM or more. I repeated this a few times to confirm the problem and then Dave tried a few things. But nothing worked, so I asked for clearance back to the hangar so that Al the wonder-mechanic can check it out.
All other planes were occupied, so we're going to reschedule for later in the week.
