Uber performance helicopter?
(OP)
I'm not really 'into' helicopters but since looking at the X3 I kinda segued into the RC realm...I'm not too sure what to make of this thing.

Pretty amazing little machines!!

The good engineer does not need to memorize every formula; he just needs to know where he can find them when he needs them. Old professor

The end over end flips are amazing, although some of the other tricks are prettier.

GregLocock,
At higher speeds, the X3 wings are producing a fair amount of lift and unloading the rotor. So the X3 becomes much more responsive; more like a fixed wing aircraft.
One benefit the single rotor X3 configuration has over the coaxial X2 is the rotor tip deflections. Take a look at the picture below. Even with the X2's small diameter rigid rotors, at high speed you can see the blade tips can potentially pass very close to each other on the side where the upper blade is retreating and the lower blade is advancing.

"quadrotors use fixed-pitch blades, whose rotor pitch does not vary as the blades rotate; control of vehicle motion is achieved by varying the relative speed of each rotor."

There is a company Quanser in Canada that sells that type of model to universities around the world for research related to control theory.
Neat stuff.
