yep should be fine, cause you are using 7955 servo, is the same that i use on my 30% extra with 3" swb arms.... you can hear the servo sing cause is trying to center all the time....digis servos does all the time. You can hear the servo bunzzing when it hit 40 deg. of deflexion on each direction, but just that. You can recognize when the servo is under huge load, and also when is just trying to center again.
