We'll have to wait for one of the "gear-heads" on the cool stuff like the automatic pull-up system. I can tell you about the Psycological aspect of the plane.
It was equipted with what the crews called "The Jerico Trumpets". These were sirens that were attatched to the front of the wheel pants, and, when engaged during an attack, gave a terrible howl.
Stukas were used as flying artillery, blasting holes that the panzers could use to break through and lay waste to rear areas. To increase panic and disorganization in the rear, Ju-87's strafed and bombed civilian as well as military targets. This is well documented by eyewitness accounts. This was total war, and war sucks.
The Stuka also possesed a strange case of the "Uglies", reminding many of a vulture. Suprisingly, to me, the Germans didn't appear to take advantage of the hideous "grin" that was the radiator. There are photo's of a Ju-87-R in North Africa with a giant snake painted on the side from the front to the rear, but this is unusual.
Hope that helps you.
