There is nothing wrong in what your instructor demonstrated to you, and the extra demo was well worth it to you and everyone else.
As for any maintainance implications from such a demo as long as Rrpm is maintained there should not be any undo stress to effect, and as there are no post flight maintanance requirements after such a incursion then rest easy with a well learnt lesson.
The main point of my rant was lost on you and that is, any demonstration should idealy be briefed and discussed in the classroom before hand, and then flown with a suitable margin of safety.
there are quite a few "Traps" that a experianced instructor can set that will bring home to the student the ease at which you can get into trouble in a helicopter whilst maintaining a margin of safety.
here's one such trap that catches quite a few
When the student is convinced that they fully understand the causes and recovery from VR (settling with power) and have covered to satisfaction exercise 15. Then on your next flight (cloud base permitting) take a camera with you and on your way back to base from the new exercise choose somthing to photograph, get them to orbit several times and pressure them to tighten the orbit and slow down so you can get you're shot ( they will very quickly get involved with what you are trying to achieve ) when you next come into the downwind position tell them stop here!!! thats my shot, and then watch what happens next.
Who whould have thought it !!!!!!!!!!!
