it is rather tough and you may have gotten a bit lucky. Usually, I end up finding that the feathering shaft or main is at least slightly bent. If you spooled it up with blades and it didn't seem to shake then you may be ok.
For a second crash though, it sounds like you are doing pretty good.

I flew mine 4 packs yesterday after finishing up the head setup and adjusting the tail. Did some flips and rolls, tried some inverted hovers at altitude with it that stuff is definitely easier on the 50 size....
