[FTC]: Tetrix V2 motor internals

Hi All,

I took apart a new motor and here are some photos of the internals. Can someone take a look at the brushes and comment? The motor was still running but they appear to be installed incorrectly. The curvature on the contact surface of the brushes is rotated 90° wrt the curvature on the commutator and that seems rather odd. Increased wear can be seen on the commutator.
