I constantly read a great deal about all the defects with this model or that model...why do muggs buy and then complain so much..?? There have been plenty of Warnings about several models, including the new Hornby Bk 5.
The only answer with ALL of them/the manufacturers is to Stop purchasing in the Hope that "Oh I think mine will be okay"... Just don't buy the 2nd-rate models and save your money.
With regards to Sam's Trains...Sam did you all a favour...he purchased a new Bk 5 and his frustration and disappointment was clear for all to see and then he said it was going back for a refund, Not a replacement!!
Apart from the obviously ridiculous high cost, as Sam has said, there's the frustration, disappointment, and time and cost... I have stuck to my initial decision Not to purchase Any new model based on the poor and defective offerings of recent-date and it's Not just Hornby because I will never purchase anything Accurascale after the constant stopping in different areas of the layout of the "Manor" class model with the wheels still spinning away...and Both models do it and No other model does this and the track is cleaned with CMX and IPA and is kept clean!! Before anybody wants to tell the World that their such and such model(s) is/are perfect then good luck with that as, like me, more are preferring the Dapol option that has a superior motor...at least in my opinion if more than sixty-five years means anything.
