I posted this in the form of a different topic. I could not find it to edit. Probably not descriptive enough.
Speed setting is set to R 100. I try to set the momentum by holding down the M button and turn the red dial while holding down. Instead of a graphic visible to indicate a change in momentum setting, the engine accelerates as if I am running it, and there’s no graph or bar to indicate change. I even try to do this after I do an engine shut down with the remote. When I press the M button and turn the red knob, the engine moves silently. I have started with the momentum settings on other engines and really like the additional realism it brings when operating. Would appreciate help or experience with this setup.
