I am having a real problem getting my ceiling fan balanced. Seems okay in the lowest speed but any higher and it wobbles. This fan does seem to be on an arm that goes into the ceiling fixture that my other didn't. I figured this was some sort of adjustment thing for oh say vaulted or slanted ceilings and when I push/lean the fan a little which moves this arm/extension thing (sorry don't know what it is to properly name it other than extension) it seems to help the wobble a little but am really not sure. Do I need weights on more than one blade? Maybe I am not putting enough on - the ones that came with the fan seem awful small to have any kind of weight to them or really do anything.

Make sure all of the blades are tight and that the arms are properly fixed to the motor. Watch the blades track and see if one is out of track with the others. Sometimes you need more weight but I also find a number of blade arms that aren't properly fitted and tightened
