What brushed motor will fit dex210?
 

I know this sounds strange but I am looking to transfer my son's brushed set up to my dex210 for him.

I have discovered that the brushed motor I have won't fit the motor mount as the bit that houses the bearing around the spindle is too thick. Don't really have the funds to go brushless at the moment, does anybody know of a brushed motor that will fit the dex210 motor mount?

How much out is it? Could you just dremel a bit of the motor mount slot out to clear?
I can't imagine you'll have to remove much material
