Default Hard mount servos

HI all, how many of you out their, hard mount your servos in Jets( no rubbers on lugs). I know their is no vibration in jets, or is their from turbulence, etc.
Pros for no rubbers=tighter fit in small spaces, shorter screws, No chance the servos will get loose from the rubber grommets drying out .
Cons= more servo wear on gears.
If more are hard mounting, what's your filler piece where the rubber was, Hysol ?
Whats your take on mounting servos in Jets

I never use the rubber mounts on jets, you need as much power as you can get and a solid mount is the best way of stopping flutter from starting

Never even thought about it. I just used the rubber mounts that came with them. Have never had a problem. If the screws are tight on the grommet, I don't see much movement that would cause flutter. Seems like the rubber mounts and grommet would help distribute the stress on the mount a bit though. Especially with the screw usually being ~ 1/8 away from the mount's servo hole.

I try and use servo frames whenever I can. They come with hard plastic inserts that fill the large holes in the servos.

You won't have to fill the servo holes with anything if you use #6 self tapping screws.
This is what I offer on my PYCABS servo mounts.



I can hang 225 lbs on a pair of these without any hint of cracking...

I 3D print plastic grommets for #2 and #4 screws for my stuff.

I have noticed the arms on servos are not perfectly perpendicular to the servo and with out the grommets it bends it a little till it sits flat with surface. I have done both nothing wrong with either, I use carbon plates on top of my grommets and dont notice any play in them.
