Servos Buzzing

[HarryNuts]

I just installed two servos in my buggy. A HS-5645MG and a HS-5625MG digital hitec servo. I hear a small buzzing or beeping sound coming from the servos. Is this normal. I'm a little new to this stuff.

It means your servo's are fighting to find their home position. You may have some binding in the linkage somewhere.

I know my maxx did this with the same servo on my steering. I loosened up my pillow balls and it goes away now if i have the wheels off the ground.

I have the same proublem i tried out my servos the other day and the steering servo buzzez but when i take the car off the ground it stops. Mine iis also a hitec servo.

Digitals are notorius for buzzing. They have super sensitive positioning and are trying to get dead nutz on center, also any slight friction in the control system (linkages) only makes the problem worse. The worst thing that happens is tht it'll run your battery down faster than normal.

I dont have any binding. I am however using a PCR laydown Throttle servo setup. My steering servo doesn't do it . Its just the Throttle/Brake servo.
I still dont know whether to consider it a problem or not. It guess its normal since there is no binding.

Mine does that buzzing noise when I first turn it on but goes away a few seconds later. I believe you really shouldnt think its a problem unless it is not doing right. If it runs OK and everything works then have fun.

Does your servo still make the noise when you take the top off?, if so then that might be a problem, but if the noise stops once you take the top off, then the servo has to be allinged.

As mentioned, this is a common phenomena in digital servos. This can be caused by the servo's tendancy to want to find the most exact center that it can when recentering. It can be caused by any load (no matter how small) placed on the servo without an actual input from the radio. This also commonly happens in brand new digital servos and goes away as the servo gets used.

I have the same set-up in my buggy. I had the noise for about the first five minutes of use. After cycling through the full range of motion on both servos for a while, the noise went away.
