I have a Protek 130 T servo that is barely over the 1 year warranty. And it doesn't come back to center like it should. I turn left and when it comes back to center it's 5 degrees or so skewed to the left. And when I turn right and back to center its 5 degrees skewed to the right. At idle, it's totally solid. Not twitchy like old worn out servos get. Question is, can you send a servo in for service? It's been in a 2 wheel buggy the whole time and never abused.
