Let me explain, in normal camera control mode them amount of force you need to fwd/reverse/up/down/left/right is okay, but turning and rotating (yaw/tilt/roll) is slow relative to the amount of effort you put in. This makes it easy to fly forward at speed by hard to turn left or right!
"Scaling of the translation speed" is a mouse wheel or + and - keyboard buttons. You may bind them to the SpaceNav buttons aswell. You should adjust your speed manually, as Harb have said. This will solve your issue with rotation/movement speed.
Also, there is a sensitivity control. Open the "Camera controls" tab and scroll it down.
