I got a new radio for Christmas with all kinds of fancy adjustments. I installed the new receiver and it works fine most of the time. Occasionally after a full left turn the steering will suddenly glitch with a quick hard turn to the right. It never did this before so I assume it has to do with one of the default settings on the radio. I read one thread where someone was having a similar problem and the culprit ended up being that the EPA was not set correctly allowing the servo to go to far to the left and then causing the glitch.

First, is this possible or did I read that other thread wrong? (Sorry, I can not find that thread again for reference.)

Second, how do you properly set your EPA? The instructions in the manual do not make sense to me. Thanks all.

You said after a full left turn, do you think it could be the response is so fast and sensitive with your fancy new radio that when you let off the wheel it snaps back the other direction a bit? I know it is far fetched but I have seen it before. The servo traveling too far is prob more likely, but just s thought.
You want to set your steering endpoints so that you just get full travel and no more. Usually its pretty close at 100%, but its always better on your servo and servo saver to back off until there is no extra stress. Turn one way and adjust the endpoint back and forth so that you can see where the steering stops, then you will know where to set it, repeat for the other direction.
