What are some of the symptoms of overspeeding the head? Specifically on a 30 sized rappy v2 with a os32.

Someone once told me that it would be 'almost impossible' to overspeed the head on it with that engine, but I believe I done did it

It basically was a violent shaking and it looked like the blades were trailing behind the head a bit. Immediately landed and quadrouple checked everything over for damage (twice). Adjusted the thorttle curve and went back up, and it was fine.
I'm running Vortex carbon fiber 550's that are perfectly balanced.

When overspeeding you will hear it and the model will be more twitchy than normal, too much overspeeding can cause stress damage to components, the model will also be more sensitive to the blades not being 100% balanced at higher headspeeds, ie more vibration

The shaking you're describing sounds more like a "woof" than an overspeed. The only symptom of an overspeed is you'll hear the RPM increase.

Check your washout arms and mixer arms on the head, I've seen V2's do the woof when one or more of the screws that secure those arms are slightly loose.
