I am getting back into the hobby after being away 15 yrs. I am picking up a bunch of new equipment and still learning about the new technologies. My question is i have a Futaba 3PM radio and s9452 digital servo. When I turn the car on the servo chatters and buzzes. Seems like it is trying to find a neutral/no load spot. Is this normal? If so is there any way to get rid of it? Do I need to change any settings on the radio?

Yeah i seen that happen and what happen is you might of hit somthing and jearked the servo and damage the motor. It is still good but if you hit something again then you might screw your servo. I would just make sure your servo saver is a tad lose.

It is brand new. Nothing has even been run yet. I am just in the process of setting everything up.

i suspect something is binding. free up the servo and see whether it's ok now.

Digitals are a little noisy anyway. It shouldn't be fighting to center itself though, it won't last long if its doing that all the time. Take servo arm off amd see if that makes most of the noise go away. Servo might not have been centered when you put servo arm on. Refit arm and see if thats any better.

You do need to set the endpoints on teh servo when you get past this so servo travel is properly limited.
