There seem to be some QC problems with Heljan. I found that one bogie of my 27 had a bit of a problem with a gear axle out of true and that the lubricant was poorly distributed. The sides of the cab were not trimmed to allow for the tablet catcher pocket and as a result the body fit left much to be desired. This was easily fixed but... The Claytons seem to be a veritable minefield with problems in the worm gear bearings, lubrication everywhere but where it is supposed to be, bunged up commutators and motors that unwittingly act as smoke generators. There is a thread devoted to these woes in RMweb: http://tinyurl.com/oploao

Mine arrives next week so I'm ready to do surgery on all the obvious things before it turns a wheel.
Which brings me to a question, has anyone tried turning down Heljan wheels to P4 profiles?
