Hi everyone.
Just wondering if someone can help..
I have a oo gauge Bachmann class 57305 fitted with a Hattons 21 pin decoder, DCR-21 PIN-DIRECT-V2. At the moment i am having problems with juddering at very low speed. The only changes i have made to the decoder is acc 150 and dec 150. I dont know if it is the motor or if it is the decoder setup. Has anyone had this problem. Any advice welcome

Ok, i would suggest the next thing to try would be to pop a another decoder in if you have a spare. I take i track is nice and clean.

Same make Brian. The Hattons decoders work well on all the other locos. At moment i have ten new locos on my layout, with the new addition yesterday. The Hornby HST from hattons.

Do a reset on the decoder, usually CV8 and keep it for another loco in the future.
