Stick for CoD

[Sokol1]

Anyone knows if it is possible to combine MS FF2 and CH throttle quadrant?

Of course, you can use MS FF2 (considered by many the best stick for WWII sim) with
CH Throttle Quadrant and/or CH PRO Throttle, Saitek PRO Quadrant, stand alone throttle of X-52 HOTAS, DIY one.
Same for CH PRO pedal, Saitek PRO, combat or Cessna pedal, Simped, etc.

Modern games see many controllers attached to PC (old IL-2 1946 is limited to four).
