HS-81MG buzzing
 

I recently installed a HS81-MG in my Vendetta. I use the CF servo holdown. The sero "buzzs" until I move it left or right. What up with this?

Sonuds like the linkage is a little tight...

I have checked and nothing is binding. I was wondering if the pressure from the top plate could cause the servo to "bind" internally. The Duratrax servo hold uses a CF plate and stand offs to squeeze the servo to the chassis.

The pressure against the servo case can cause this buzzing. Also if the servo case itself is a little tight it can also cause buzzing. In this case you can loosen the case screws slightly to releave the pressure.

I backed off on the top plate and the screws in the servo cast just a touch. No more buzzing. Thanks.
