Brushless Motor Build Question
I recently picked up a used 17.5 motor that runs, but when I look closely I can see the stator moving for/aft in the can when I give and let off power. Are the stators normally glued to the outer cans or are they a snug press fit? I don't think a stator should be moving, but thought I'd ask.

I could also be wrong and it works just fine for forever.

Might want to use heatsink compound instead of glue.
The stators are usually, 'interference fit', so if tyou need to fill any gaps the compound will be better, otherwise it won't transfer heat out through the can as well.
When you check the temp after a run, measure the outside of the can as well as the inside through a vent hole.
I usually get 5-7degC difference (hotter on the inside)
