Actually its all of the animation .  I have a SR71 Blackbird and the landing gear, chutes and rudder movement will not display.  Now on my friends computer, the exact same plane does display.  We both downloaded a FS2004 SR71 and the gear does not display on either of our computers. I  have read that planes created with some design programs DO have trouble showing up the animated surfaces and itmes in Fs9.  But why would the same exact plane show the gear on his computer, but not mine?    We have checked all the display settings in FS and set them identical.  We do have different Nvidia cards.
  What else to check?
