I would use the rubber grommets that come with the servo to take up the space but the instructions do not show this and also when I did try the rubber grommets the self tapping screw is not long enough. I tried with a longer self tapping screw with the grommets, the thickness of the rubber made the servo sit too low in the chassis so the arm was contacting the chassis.

Do other servos use a smaller mounting hole? I've not seen this dimension listed on the servos specifications. Is there something else I'm missing?


The servo is a spectrum z590.


Thanks
