Delay between the joystick axes input and the actual movement of control surfaces

[Untamo]

S!

I have to agree with Luno. I am quite sure it's the simulation of pilot muscles vs. the force control surfaces put against them. So, think of your joystick as the pilots brain, as in, what you want to do. When you deflect your stick, the pilot in-game starts to move his hands, almost instantly, but working against the control forces.
