Servo
 

Just looking for a little clarification. Got a Savox 1258 digital servo and have put it in my SV2. Only thing is, it makes a sort of buzzing sound, static sound. Is this normal? It does seem to be working fine

Cheers.

my 1251 low profile does that too.
By the very nature of how the servo us working, it's trying to zero at rest. A slight bit of pressure of say tyres on the ground can put a force on the servo which it works against to zero, resulting in the noise from the motor. it's normal, but unnerving when its on your workbench.

Thanks for this.
