Just reinstalled FS9; all of my planes trim full down in flight! My stick is OK, checked it out immediately (I thought it broke and some buttons were stuck or something).Never saw this before, or heard of the problem. How can this be cured?It's a clean install, nothing left behind from old installation...no folders or anything.Thanks!

Have you tried loading the FS9 C172 Default flight out of Seattle or whereever it is then switch over to the aircraft of your choice from the aircraft menu? That will usually neutralize any out of whack controls settings.Also check that the autopilot isn't defaulting to being on and in a climb mode.Also, can you neutralize the setting when still on the ground by pressing number pad 5 for a few moments while in "numbers lock"?

are you using any weather program in the background?If so, check wether that happens without it.
