I've received my Dapol BR/SR Class B4 loco from Rails, seems a nice little loco, runs beautifully with (according to the supplied "Owners Manual") no need to run in the loco. It's a bit of a 'faff' to fit a decoder, 4 tiny screws to remove the bottom plate, turn back the NEM pockets to expose another 2 tiny screws to finally ease off the body. Then you find that a standard 6 pin decoder is way too big! Dapol recommend their own 'Imperium 6p' decoder ( no surprise there) but it's been said in print many times " don't buy decoders from the big model manufacturers", Hornby being a perfect example of what not to buy in my experience, but looking on the Dapol website it seems that this particular decoder is not even listed! I need a 6 pin decoder for this loco, but the decoder body (not including the pins) maximum size is only 10mm long to fit into this loco. I can (and have) removed entire circuit boards from some loco's to create space but I'm loth to do this with this particular loco, bearing in mind past problems Dapol have had with some of their electronics, since obviously this would void the warranty. So, here's the question, does anyone know of a suitable alternative 6 pin decoder of a size that would fit this loco, from a known decoder manufacturer rather than Hornby/Bachmann/Dapol, maximum body length 10mm,(excluding pins) width no more than the 6 pin plug itself, and as thin as possible?
