My MSR has a proble. When in a hover with no other input besides throttle it will rovk back and forth or side to side. i can't fix it with trim because it will sway forward and then back. What could be my problem?

Kruser listed a couple things that can attribute to the toilet bowl effect that your having. Most likely the blades to tight in there grips more than the swash being unlevel.
Has the mSR been wrecked just recently and have you added any new parts to the bird by chance ?
A few things to check is to make sure your flybar links have no friction on them. Sometimes with these cheaper RTF heli's there will be some "flashing" there, or a "ring" of plastic around the ball. Make sure those ball-links move freely... Use a knife or sandpaper to remove that flashing. Any resistance in the flybar linkage will cause TBE.
Also check that there is no binding of the flybar inside the center mount of the hub. Check to make sure your flybar is not bent, that is a common issue also with TBE... A bent shaft also will cause your problems, so make sure that is good to go among that. You can take your main blades off and check to make sure your shaft is still true.
These heli's whether large or small are delicate fabrications, and require everything to work together smooth and free to have a nice flying chopper... Check these things, and see where your at. If the problem is still there than there could be some other things that you can check. Check these first...
Hope this helps,
