Trim - This is where the servo centers itself. What you want to do is make sure that your radio's Trim is set to 0. When Trim is at 0, the servo is at dead center. Having positive or negative trim allows us to center the steering or throttle because when we set it up we are not 100% accurate on getting the steering straight, or the throttle setup exactly right. Trim adjusts us for that.

End Point Adjustment (EPA) - EPA is a setting that controls how far the servo will travel in a diraction. The DX3 supports seperate endpoints for both positive and negative servo travel (IE: Left and right for steering, or throttle and brake). So lets say the throttle slide is fully open at 70% of throttle travel, adjust your throttle EPA to 70% and it won't put undue stress on the servo, or the throttle slide/carb. This will make sure both the servo and the batteries last longer, and that the throttle slide doesn't get worn or even pulled right out of the slide bore.

There are a crap load of other options that the DX3 has, and other radios like the 3pk, M8, and M11 have even more.
