Yes I recieved my D last week, and after running-in, found it ran tolerably rather than impressively. I fitted the Dapol Imperium decoder and have yet to experiment with the basic settings but find it runs too fast. It also reminded me of old Lima models. Wickham Green's suggestion is good, I hope you get some satisfaction from Rails. If anyone has any recommendations as to settings for the decoder I would be grateful.
There is alot I like about the model, the close coupling to the tender, spare axel and detailing parts, and the swopping of the NEM socket for a blank on the front bogie.
On the downside, I found a coupling hook detatched, two of the buffers fell off, and my huge fingers erased some of the fine lining off the running boards whilst handling it, fitting the decoder chip. I really didn't like the silvery handrails, coupling hook, or con-rods and the bright dayglow red of the bufferbeam & piston rod detail. Since last week I have blackened the silvery bits, re-numbered it, added 247 plates, real coal, crew and detailing pack, then lightly weathered with a mucky satin varnish to tone down the brightness and seal it the numbers & plates....so before and after........
