- - Servo Buzzing (https://www.rcuniverse.com/forum/rc-helicopter-general-discussions-129/9266740-servo-buzzing.html)

I have a couple servos that are buzzing on my raptor .50. Is this a normal thing to hear? Not all of them are doing this, just a couple that I noticed. The servos are S3152 and the tail servo is a<span style="font-weight: bold;"> S9254</span>

What would be causing this, or is this just normal operation? There is no clicking, and the servos are getting there full range of motion with no binding or hesitation. Also they only buzz when you are moving them via the receiver, after a few seconds when you stop mving them the buzz goes away.

Any ideas or suggestions, I would be happy to hear them. Keep in mind that I am a beginer and this being my first build.

RE: Servo Buzzing

Digital servos buzz, all of them. Not to worry.

RE: Servo Buzzing

Cool, thanks again for your help. You have such a wealth of knowledge, which I am thankful for.

Take care.

RE: Servo Buzzing

Digital servos do buzz, but make sure there not binding. Take of the servo arm and move them and see if it's the same buzzing.

RE: Servo Buzzing

Hi I've got a servo related question. My Esky Belt cp v2 has had more time on the bench than in the air since I got it.
First attempt at flight main gear stripped all it's teeth (motor meshed to close)
Second attempt light on skids slid sideways into outdoor table, new blades, feathering shaft and flybar.
Third attempt decided to test a little more before doing anything rash went to approx 50% throttle and back to zero, motor increased rpm heli leapt up and nosed into ground motor sreaming blades flailing. Disconnected battery disassembled bent feathering shaft new blades flybar maingear. Also elevator servo was whirring away.
The gears had been stripped. Tried it in another channel and it still whirs even without input.
Question is: Is it only a faulty servo or is there another problem (besides the obvious one me)

First, just so you know, you should start a new thread when asking a new question not related to the original post.

But to answer your questions, it's common to strip cyclic servos in a crash. The servo may whir when the gears are stripped because it keeps trying to reach a certain position but nothings moving.

You should always check the swash movement before each flight. Move the cyclic back and forth, left and right and make sure the swash moves in the same directions when looking at the heli from behind.

If the motor reved up when you moved the throttle stick back down to zero, it sounds like you may have inadvertently switched to idle up. Make sure you're in normal mode, not idle up, until you get a hang of basic flying.
