I am in the proccess of building a Century Hawk helicopter, with a Futaba GY401 gyro and a S9253 servo when I turn the radio on the servo starts buzzing like its stalled. But its functioning correctly, I thought it might be the Gyro so I connected the servo directly to the receiver, and I still get the same noise. I have never delt with digital servos before and Im wondering is this sound normal? it is rather loud, or what is the problem?

Had the same thing with mine on my Caliber. If the linkage is not PERFECTLY friction free, then it will buzz. I eventually did away with the caliber z-bend linkage and went with a carbon fiber control rod....no more buzzing for me

I can't say for sure without hearing it but my 9253s & 9251s also all buzzed. It seemed to go away after a little use. It may be that once the gears wear in it can get centered correctly.

Thanx for all the quick responses, I thought the servo might have been defective.
