Taxiied and took off. Pulling back the throttle to begin decent for the
first touch and go delivered another nervous moment. A fairly strong,
unusual vibration was felt. As we were not on the ground, my mouth
instantly did an impression of a cats bum, and gauges were frantically
checked. My instructor suggested that the prop may not be 100% balanced
properly after being re-dressed. Turned out that must have been
correct, as it did it every time we throttled back, and caused no ill
effects other than the unusual vibration.
We did 2 touch and goes and a full stop with the instructor with me,


Oz, I'm trying not to read too much into this, but it seems to me that
you and your instructor should have landed the plane after
experiencing a "fairly strong, unusual vibration".

I've found that "strong, unusual vibrations" usually lead to bad
things happening in airplanes.

Otherwise, glad you're back in the air!
