First question and hopefully simplest, is any sort of wobble expected for a brand new ceiling fan install? I installed 3 Hunter ceiling fans in my house this week, one of which was mounted to an existing wooden support in the ceiling and two that I had to add a new fan brace/box for in my attic (for reference, I used one of those "new" brace kits as I had attic access to the joists). The fan that went into wood does not wobble, the two that went into the brace do wobble. I'm trying to figure out if they require balancing (which I'll be trying) or if I screwed something up with the install.
The second question is with one specific fan. It seems to have an odd ellipsoid motion around where the fan blade supports are mounted to the fan housing. I'm not sure if it is an optical illusion to my eyes after working on it for so long, or if there is something off here. And if off, can it be adjusted?
Here are two videos showing what I'm talking about. The first one you can see the motion, the second is a bit shorter but you can see a bit of wobble caused by it.
I should note with this particular fan (with the housing wobble), there is about a 1/4" variance in height from ceiling to fan blade tips.
