I guess I like to set the sub near zero, trim at 0, d/r at 100% then dial the pot just a little to get close, then finish the alignment with sub trim. I only use trim on the track, nothing more then a click or two from center. I set the epa's to just buzz the servo and back off a couple. Then I will take the d/r down to 75%. When hot lapping prior to the heat, I will go up or down depending the steering needed for that heat. Some like to do epa only and ignore the d/r claiming they can not keep the ratio correct if they use d/r. Just a preference thing.

But the adjust pot in the JR servo is a little known "goodie".
