    I just installed an mrc decoder in an athearn bb for a friend it now goes from 0 to 50 mph when starting. the sound speeds up ok but the loco doesn't move until going fast. I changed the start voltage to no availe I put 5 in on momentum and it helped but would rather not use momentum. what do I need to do?
