Placing the Cube near an ESC

So I wanted to place the Cube near an ESC.
Should there be any electromagnetic interference from the ESC to the Cube’s IMUs and compass?
I also plan on locating the Cube behind COG.
Will there be any meaningful consequences?

It should be fine as long as there is no crazy levels of noise going on.

There are settings in Ardu for the FC position

What do you mean by crazy levels of noise and how can they effect the system?
Have anyone experienced issues regarding this topic?

I know that there are issues regarding relocationg the FC, will they still exist after I change the settings? Or will it fly just as if it is in the COG?
