'They may be stronger than you think... See https://www.youtube.com/watch?v=Z-zI_VpTFp8 which shows almost the same chopper flying into a powerline which'
The R-44 in the video has more substantial rotor blades than the R-22, which would be nice but they're on about the 8th modification state and they still have problems with them coming apart. It's also worth noting that they're unlikely to take-off again in that aircraft until they've had the blades replaced, unless they've got a death wish.
Report here of a similar incident with photos of the damage: http://www.aaiu.ie/sites/default/files/report-attachments/REPORT%202017-014.pdf those dents will have substantially weakened the blades which are basically an aluminium skin around a spar and honeycomb structure.
I have flown the R-44 which is about the least robust helicopter I'd like to fly in on purpose.
