Dan Griffin Posted July 4, 2018 Share Posted July 4, 2018 Good morning. Yesterday I purchased a 4F loco which I was lead to believe was a Hornby product, as it has a Hornby base plate. The model is lovely and has been detailed and weathered by the previous owner. it has real coal in the tender, screw couplings etc. It even has replacement pick ups on all driving wheels, and its tender driven which I'm no fussed about. the loco is in the 'preserved' fleet so will not be doing a great amount of running. I have never attempted to convert an Airfix GMR model to DCC, and my question is, how do they run on digital? are there any special considerations to think about? It is a simple enough affair to chip it as there are no capacitors or anything like that. The Airfix 4f The replacement pick up arrangement the basic motor and wires. there is plenty of spare room in the tender for the decoder. regards Dan Link to post Share on other sites More sharing options...
34theletterbetweenB&D Posted July 4, 2018 Share Posted July 4, 2018 Have you given it a test with DC? (Use a 9V (PP9) block battery if you have no DC controller to hand.) It has to be an adequate runner by your standards to be worthwhile converting to DCC. Assuming it runs adequately I would go straight to a Zimo decoder with this motor, as they have the range of adjustments to obtain all the potential performance from such mechanisms.

Dan Griffin Posted July 4, 2018 Author Share Posted July 4, 2018 Yes it does run very well with a dc controller 1 Link to post Share on other sites More sharing options...
RMweb Gold Barry Ten Posted July 6, 2018 RMweb Gold Share Posted July 6, 2018 I've got a couple of these mechanisms running with a basic Hornby decoder, and they run very nicely on DCC. Link to post Share on other sites More sharing options...
