Got my HST and 4 Mk3’s today and 1 decoder (explanation below) - I know others have already said, but these models are fantastic, really impressed with the detail.
anyway, quick check on DC to check runs freely then opened up to fit HM7k decoder, lifted cover to check motor wires on flywheel (thanks Richard) and fitted single decoder and speaker, routing wires to avoid screw (thanks Peachy). Paired up, updated and all good to go so been running in this evening.
so I have it running with one decoder, blanking plate left in dummy and still get lights on Dummy though will are not directional i.e. they will stay on same colour irrespective of whether your going forwards or backwards, suits my needs at the moment as majority of time being pulled and happy as sound from front is more than ample and saves expense of 2nd decoder, but will see how we go - I may well add later and definitely be adding a stay alive and coach lights 😉
