You can get hurt or inflict harm on another person in the blink of an eye.
I get apprehensive when my f450 or f550 starts to drift back towards me. I know that if one of those ([email protected]) 13,616 RPM rotors gets me, it's a trip to the clinic to get sewn up. So don't let the fact that it's a multi rotor fool you. They are still very capable of doing harm to any one.

Quad w/10" props at 14KRPM=tip speed of 439822.978 inches per minute
450(18") at 13616RPM=tip speed of 769966.672 inches per minute

It's the tip that does the quisinart on you. Then, we also have the mass issue. A 450 CP heli weighs more than a 450 quad and has greater velocity. So, mass X velocity squared means a cp 450 heli hits a boat load harder.

Quads are safer!
