I agree the Bus design has some inherent flaws. But I disagree that it, simply by its design, somehow diminishes a pilot's hand flying skills.

I flew it for a while and if you click off the A/T and A/P, hand flying basics are there just like any other airplane. But, you have to dump out the Bus koolaid that seems steer many guys to think it's best to use automation all the time. There are lots of pilots quite content to hand fly 30-60 second at the beginning and end of each flight and call it good (usually with an excuse about why it's safer). After they do that enough, I have to agree with them - it is safer because they can't fly very well anymore. If you saw ham fists coming out of it, that was probably more likely a result of them choosing to let their skills degrade (or they never had them).
