Reminded me of a full sized incident that happened locally recently. I know it's not ground resonance (muppet on ground pulls cable into main rotor), but impressive anyway. https://www.youtube.com/watch?v=v5aMT9MBfZI and https://www.youtube.com/watch?v=dEJzJqZWgmk. Note in the second video that the pilot gets thrown from his seat and falls back in to the rear seat. Talk about luck!

Yup, you are right Andrew! I was mislead by someone who wrote an article in local newspaper. Title changed.
This is the cause of ground resonance (http://en.wikipedia.org/wiki/Ground_resonance) not necessarily unbalanced props..
You can see a similar situation in this MacGyver Episode clip...the pilot quickly realized the problem and lifted off immediately.

Yeah, helicopters don't really fly, they just vibrate so badly the earth rejects them.
