Can the momentum be changed on the FA2 ? If so what CV ? Mine jumps with each speed step change , not smooth at all. Thanks .

I have been trying to set up 2 S-4 in consist with Prodigy express but I am having problems.
Using the Prodigy instructions I can get them to run properly with engine and turbo sounds .
Sounds awsome. Problem is I loose all other functions , lights , horn , bell and mute.

After I set up the consist do I need to program the missing functions into the consist address ?
I am hesitent to change CV's unless I am 100 percent sure I am doing the correct thing .
For now I have them reset  to factory defaults.

Anyone know if the sound decoder in the S4 can be reset to factory defaults ?
I changed the CV for bell rate and master volume but seemed to have
messed something up along way as now the lights do not work.

It's a great engine, well not so much in the dark now , but I am new to DCC.

I have a DC 2-6-0 that I want to convert to DCC . Does Bachmann have a plug in decoder or will I need to hard wire. I have not disassembled the engine yet , want to know what I need before I do so .
