I dont possess a DC controller of any sort. so cant test it that way. I started this lark a few years ago, going with DCC from the start & this is the first time, with any loco, from any company, that I have had such problems. To be frank, I cant be bothered with all this messing about with CV's etc. I just want the bloody things to work, out of the box, like they should.

Mines exactly the same. Had a long series of emails with Dave Jones re. CV settings but it still sounds like an old diesel tractor ticking over & jerks like a very jerky thing at low speed. Mines going back as well.

Thanks again. I cant try it without DCC chip, as my layout is 100% digital control and I dont possess an analogue controller anyway. I have tried it with a Bachmann 557 chip, a Sapphire and a Laisdcc chip. All give the same result. I appreciate all your suggestions but as a non technical person, all the jargon goes right over my head (Vmin, Vmid and Vmax bemf etc?) To reiterate the problem. At low speed it jerks badly whilst picking up speed. The motor is noisy, like an old diesel tractor ticking over, Plus it derails at points, even going straight forward. As stated, I am not very technical and have never had to deal with anything like this on all the Hornby, Bachmann & ViTrains locos I have. Just very disappointed that such an eagerly anticipated addition to my fleet requires such a faff.

Thanks for the advice chaps. Nothing works so must have got a Dud.

Just got the DJ models class 71. It's very noisy and jerky at low speeds and flat out only goes at about half speed. Anybody know if cvs can be altered to aid this? Using a Bachmann decoder with Hornby elite controller. Have tried another decoder but no different Thanks for any advice before it goes back. Just got the DJ models class 71.

Thanks. Never used this before. Advised by Dave Jones to ask on here.
