Some time ago I noticed one of my Mallets had an engine set (front) that was turning noticably slower than the other (rear).  In other words, the rear engine set was pushing the front set around the track.  After spending a good amount of time checking quartering and circuit paths, I finally decided to check the motor itself.  Sure enough that was the problem.  I went ahead and ordered another motor from Aristo and this is the video that shows the difference in performance. 


You can see that it's much harder for this motor to get running and at the same voltage won't turn anywhere near as fast as the other through the entire voltage range from low to high.  You can also see how jerky it is. 


I'm posting this to share with everyone for troubleshooting purposes and not to make a point on QC.  If you have one engine that is faster than another and it's identical, this could be a reason.  Swapping out the motor was not a problem.   If you run the engine by itself and it's not articulated then I don't think this will be an issue or something you will notice.

Note that this motor is the same used in the Mikado and the Pacific.
