John, momentum settings have little effect on this engine. I think I was doing that test on the bench with a DCS remote that shows what step your in. Most engines I run on heavy. Part of the problem on heavy with this one was you turn the Cab wheel in the normal fashion and next thing you are going at warp speed. Speed step 2 in this one is equal to about 20 in the earlier version. For switching moves I found it best to use a DCS remote. It gives you a positive click for each step so you don’t get carried away. The problem is the big difference in speed from one step to the next. Momentum may get you there a bit slower but it’s way to fast once you get there. Your constantly spinning the thumb wheel trying to adjust the speed. I ran it in a drag race with the earlier Legacy version. Both programmed with the same I.D. . This one walked away from it. I did a lot of testing. I want to say that when the newer version is in step 2. The older version is somewhere between 15 and 20. The original Odyssey version ramped up very slowly through the first 12 steps. After that there was a dramatic increase in speed as you got to the higher steps. This one has a dramatic increase in speed right from step 1.
