How long does it take on average for a control surface to deflect by one degree? I know this should vary quite a bit (because of aircraft size / use / build / actuation / control surface weight), but I was wondering if anyone here could ball-park some numbers on how long it would take a control surface (aileron/flap/vertical stabiliser) to deflect by one degree on average. 

I am writing a small aircraft simulator, and would like to try and use realistic numbers if possible. 

If these figures are too variable, I would love to know some ball-park figures for some example aircraft if possible.
With hydraulically actuated flight controls, the deflection speed is only limited by the maximum hydraulic fluid flow through the servo valve. I've taken some step responses of civil airliners in the past, and on-ground they can deflect full range in about 1-2 seconds.

For a mid-range passenger jet:


Elevator range = 42 deg, max no load deflection speed = 66 deg/sec
Aileron range = 40 deg, max no load deflection speed = 66 deg/sec
Rudder range = 48 deg, max no load deflection speed = 56 deg/sec


At higher airspeed the maximum deflection angle and speed become less due to aerodynamic blowback - by design, to limit the inertia forces on the airframe.
