Originally this was meant to be a short video showing the fitting of a Bachmann 21 Pin Decoder (36-557) into a Bachmann 3F locomotive (31-627B). I'd never used 21 pin decoders before so wanted to record my experience. However, after installing the Bachmann decoder, the model didn't run well, much worse than on analogue. I couldn't get smooth slow speed running, there was very little acceleration and the speed was inconsistent.
I tried everything possible to improve the performance with the Bachmann decoder including a full reset and adjusting the configuration variable (CV) settings. I managed to get smoother running, but still very poor slow speed motion.
In the end I gave up with the Bachmann decoder and ordered a LaisDCC version which gave great performance straight out of the pack.
This doesn't necessarily mean that all Bachmann 21 pin decoders are rubbish and that all Lais DCC decoders are amazing, because I've had same issue, but the other way round with my Bachmann Webb Coal Tank and the Next 18 decoder.
What this does show is how bad performance can be affected when a decoder isn't right for a particular model.
