1kg+ isn't that micro. Not that big either.
I've also got a tiny 300-sized traditional (collective pitch) heli.
That one tried to attack me with the tail rotor once. The design is kinda wonky, it's a downscaled 450 size, meaning all the shafts are just proportionally scaled down, more or less. Which is stupid, because they're too weak to handle the RPMs (or, rather, they need to be perfectly straight, which they never are).
The tail rotor was acting up. I was testing the heli while holding it in my hand (stupid, i know, but at least i was holding it above my head and directed off the rotor plane). The tail rotor spun up, worked fine for a little while, started vibrating all of a sudden and then the straight line of the shaft blurred into a cone about 2cm in diameter. I had about enough time to go "Ohshi..." and then the shaft snapped, whistled by me and dug a little hole in the wall.
