It's very, very impressive. One of the things most people don't realise about controlling RC planes, helicopters, even cars is that it's in many ways much more tricky than the real thing because you have to constantly put yourself in point of view of the thing being controlled. eg, when the plane is flying away from you in a straight line it's easy, move left makes it move to your left but if it's coming towards you then move left makes it move to your right...put that all into three dimensions and it starts to get very tricky.
