Gidday, can anyone tell me what causes my servos to hum. I have a jr xf631 radio with 537 sevos. When i move any control surface the servo continues to hum for a approx 10 seconds after i have returned the stick to neutral.

Is anything binding? What size/voltage battery are you running? If anything is binding, or if the control surface is stiff around center, the servo will work for a little while to get the surface to where its supposed to be.

I've got a few of those 537's. They seem louder than other JR servos. Dont know why... I do know that Digitals buzz all through their operating range. Thats what they do.

I think you are fine.

I have four brand new JR 537's in a new Hog Bipe and I'm having the same situation.

The servo's seem to buzz several seconds after they are actuated and then it stops.

So far hasn't affected the the flying and I ve been watching the battery drain. I check after each flight and the receiver battery dosn't seem to be dropping any faster then previous.

I heard that these servo's do buzz a little, I don't know why.

thanks for your replies, the voltage is 4.8 volts, sometimes the humming stops after a short duration other times it keeps going. Ive checked the control surfaces and they seem to be free and easy. Oh well, looks like i might have too put up with it. Thanks again fellas.

If after a few seconds the humming stops and there is no binding, I wouldn't worry,some times the weight of the control will cause them to hum a little,I've had the wind while at the flying field cause them to hum.
