Hello, I recently bought a class 67 DCC fitted R2522 but when I gave it a test, it seemed to slightly stutter. My other locos work fine on the track so I don't think that it is a problem with the track. The stuttering is also in a regular pattern not like you would see if the signal was being interrupted by dirty track. The stuttering is very slight and hard to notice. I have heard that it may be a problem with the decoder or a loose drive shaft. I havent taken it apart yet as I dont want to damage it accidentally.
