Hi Buck:
Having been a Beta tester with fairly extensive experience using Instant Scenery for personal FS projects, I am confident that your described user aircraft slew behavior is
not due to any of your add-ons (including IS3).
I would
not expend time / effort un-installing 3rd party add-ons that you may still wish to use in the future, as, IMHO, they are not likely the cause of the IS3 Slew mode control issues you describe above.
IMHO, instead we need to inspect:
FSX Menu > Settings > Controls > Control Axes >
Controller Type = Saitek X52 Flight Controller >
Flight mode = Slew
Note that one can configure mapping of controller Axes in "Normal"
or "Slew" mode by 'ticking' a radio button type of control above the list of FSX functions for a particular selected type of game controller attached / mapped in FSX.
FYI: I also use the Saitek X52 (original model) USB HOTAS controller with FSX, and have had the same symptoms you describe, with the user aircraft spinning or flying away over terrain when I toggle Slew mode with the "Y" key and/or activate IS3 into object placement mode.
Typically this
mis-configuration occurs if certain controller Axes are linked / mapped to the
FSX user aircraft Axes for
Slew mode.
For example, the rotary dials on the Saitek HOTAS Throttle may be linked to FSX Rudder Axis and cause the user aircraft to 'spin' rapidly.
First, remove mappings for any
non-Saitek game controllers and/or FS features
not intended to be used on your (2) piece Saitek controller.
After calibrating the controller via FSX Menu dialogs, test removing / re-assigning controller Axis mappings for Slew mode, then re-calibrate.
BTW: For more precise object placement using IS3 via a joystick controller instead of a Mouse, you may wish to use "
Slew Assist" :

PS: For IS3 object placement that does not require as much precision as is enabled using a "Slew" utility with the game controller mode, I believe you may find that it is easier to use IS3 in its 'new' Mouse mode, rather than via its 'legacy' game controller mode.
I would recommend instead assigning the Left Mouse Button in IS3 Add Objects mode, as shown below:
Let me know how this process works for you.
