Hi all,
Just a note that as part of the "body for a roco loco" thread i've strated in locomotives, i'm going to be chipping my first loco for DCC at the same time. I'll be using a Zimo MX620 decoder and a Bachmann Dynamis controller. Hopefully i'll have space within the body to incorporate directional lighting. I'll post my exploits here.
Brave man using the dynamis - hope you stay close to and in direct view of the receiver at all times! Seriously though, I would be interested in how you get on with it.
Those new hornby R8249 decoders look great - 4 functions, small (fit in most 009 locos) and NMRA compliant - all for
Hi Colin,
I've heard several different views on the Dynamis, some people say there's no problem with connection to the base and others say there is. If it's too bad then i'll fleabay it and get an NCE powercab as that was my second choice.
Hope you don't mind me saying but Hornby decoders have had a lot of negative comments about them frying and smoking on RMweb after short periods of use. Hope the new ones are different, i've been told the Bachmann ones are much better are only a little more
I think the likelihood of decoder burnout in 009 is much less than in the larger scales and I suspect the problems are caused by people chucking loads of amps through these decoders when they are only rated for 500mA. In 009/N gauge that shouldn't be an issue at all. and of course this is a totally different decoder now, with a new code number and that important NMRA compatible tag!
Bachmann may have better reviews for use in largher scales but they are also huge - you'll find it difficult to fit them in quite a few 009 engines!
Otherwise you would have to buy the small zimo/gaugemaster/lenz/ztc decoders at
Trure, i'd not thought of the larger drain on bigger locos.
Anyway, at present my loco fleet is still quite small, i'm using Zimo MX620 decoders which are about
Hi Tom
I wonder if the chip you are using has back EMF which I think is quite important to ensure smooth running

John,
as well as the "shunt" function which cuts the top speed it does have back EMF, full spec in link below...
