Ya, my servos only buzz, if I push the control sticks all the way. So it's okay like that?
Well not really... ( with exceptions... )
This indicates that the servos still want to travel more, but the control surface is at it's limit.
With the plane on, put your computer controlled TX into setup mode, and LOWER the travel adjustments as you keep the sticks to their extremes.
Try to adjust the TX so that the sticks can still move to the extreme, but the servo buzzing stops.
