Hey Graham I think it is subjective.
I know that my old man who has an electric engineers background, does the same thing as you when looking at the machines, but at the same time marvels at the way these things are set up.
He like you, loves the look of the Goblin after i showed him, and the engineering in it just blows his mind.
I don't like the aesthetics of the warp, but love the simplicity of it. For me the skids don't look right (i like things to scale), however the head on it looks awesome, and the stabilisers grab me!
From other research i've done, most of the guys who are competing and doing hardcore 3D, almost none of them fly a standard helicopter. They've all stretched the tail, or done something else to their bird.
I do like the Align heli's, and the cnc machined heads on them.
I hear what you're saying Graham and understand totally
