The blade spins at 1000rpm, and can do a bunch of damage to aluminum and weak titanium.

There's also a small 2kg Pussycat style blade at the rear, powered by a 24v S28-150 Magmotor, it spins at 1000rpm, and can scratch most thicknesses of titanium.

...both these blades seem to be the same and yet have different capabilities? :S
