I received my D40 a good few weeks back. It has needed an inordinate amount of "fettling" and more to get it to work, some of which has been spoken about in the GNSR Review by Des, their modelling guy. It still isn't running very well, due it is believed, because it still too light and needs someone who knows to put lots of lead in at least the tender and over the front bogie. Has a formal review of the loco appeared which gets to grips with all the issues and posits solutions? As a useless bodger only i'd love to find some to take it away and return it running perfectly. Please. But it looks wonderful on my window ledge. Sigh !
