The only surface that was controlled with electricity was the stab, which used an electric powered screw jack to change the incidence.
The ailerons used rods only while the rudder and elevator used both rods and cables.
Ok.
Now I confirmed, the late D models would feature eletric surfaces.
You mean late -11's? -13's?
-9's were little more than the standard A-8 airframe, with the "Jumo" mods for the weight and balance "issues".
Got a source?
Care to share it?
Or is this another "Luft '46" thing?
Guys, some doubts:
The 190 can be considerate as an aircraft with a Fly-by-wire system?
It was pioneer, electrically controlled surfaces were used by other aircraft in WWII?
How it provided a differential in damage control in comparison with other control surface systems?
The tactical significance of the system to maneuvers was significant?
The system had palpable disadvantages?
Thanks since now for the answers.
The turret was turned by a hydraulic gearbox. The gunners feet rested on a tilting platform. If he pressed the tip of his foot toward the front, the turret turned to the right; if he pressed with his sole to the rear, it turned to the left. The more he pressed in the corresponding direction, the faster the movement. At it slowest, a 360 degree revolution of the weapons in the turret took sixty minutes. At it quickest, it took sixty second. Extreme aiming accuracy was thus ensured. The practised gunner didn't need to adjust afterwards with his hand.
Wasn't this just an option for manual settings? AFAIR they had an automatic hydraulic system in the BMW 801 except the 801A series."Stona" is absolutely correct in his statement the only thing to add is the electric driven propeller pitch controll.

Along that same line of thought....
Otto Carius (Tigers in the Mud) provides a good description of how accurate and responsive the Tiger Tank hydraulic turret motor was.
The last sentence is the critical point. WWII tank gunners had a handwheel for fine adjustment of the turret. Not having to use that handwheel was a key advantage for Tiger Tank gunners. It often allowed him to shoot first, while his T-34 opponent with electrically powered turret was still struggling to aim.
What is the advantages of eletric trim with hydraulic surfaces, just the possibility of use the trim tabs to control the plane in case the hydraulics failed?

When you are flying, especially a high performance aircraft, you are continually trimming the aircraft around the pitch axis. There will be the need to trim during climbs, descents (adding or reducing power), when the flaps are deployed or retracted and when the landing gear is raised or lowered. Usually a trim wheel is installed and is turned as required but you are taking one hand off the throttle to do this. Aircraft with electric trim usually has a switch on the stick or yoke and trim can be easily activated with the thumb.The electric motor alters the angle of incidence of the tailplane,the horizontal stabilisers. It doesn't work on the elevators.
This method of longditudinal trimming by "tilting" the tailplane was common to many German aircraft of the period. The tailplane of a Bf109E had a range of near enough 12 degrees (+3.4 to -8.4) but no electric motor. The pilot had to crank the trim wheel,one of the two big wheels (30cm) to his left,5 and 3/4 turns to effect the full range of movement,though I can't imagine why he'd ever need to do that in normal flight conditions!

at least in the FW190 the propeller pitch control at the BMW801 is the electric driven both in the auto and manual mode which is selectable by a switch. To control the manual mode a rocker switch is provided at the throttle lever.

Yes. These controls.
The Fw190 had a good engine and propeller management system (kommandogerat) which meant that the pilot could manage everything with that one throttle lever. The management system set the propeller pitch,timing,mixture and,if I'm remembering correctly,supercharger gear (someone else may have to look that up).
