Try this...
I'm using the X52 throttle quadrant with a Microsoft precision pro stick. I have 1 of the buttons on the stick set to "hold to adjust view"(Under the camera settings..controls). while holding the button down, i can use the thumb mouse on the joystick to seamlessly zoom in and out as far as i need.
You also need to have the saiteck Smart_Technology_7_0_2_7_64bit software installed..if your running a 64bit OS.
They also have a 32bit version also.
No profile needed to run it either, I just have the software installed.
