JR Servos Buzzing
Question: I'm setting up a 35% Carden (a step up in plane size for me) with JR DS8411 servos that are not brand new. The servos and installation seem to be fine in that there is no binding of the linkages, no slop, they respond well and seem to have good holding power but I'm getting a lot of buzzing from the servos at neutral. The buzzing goes away when the stick is deflected. Is this just typical with JRs, or because the control surfaces on a 35% are so much larger/heavier than I'm used to, or is it indicative of a problem with my servos?

Re: JR Servos Buzzing
Digital servos, they "sing", that is normal.

Re: JR Servos Buzzing
And JR servos tend to "sing" more than others. If you gently lift the aileron to take the weight off the linkages and the humming goes away......you are fine.
In flight, the airflow over the wing will keep the surface from sagging on the linkage
