Rubber Thingy lol

[demonoid369]

So I searched but didn't see or hear anything on the servo rubber things that go on the ears, how many of you use them and how many don't? I was debating on if I should leave them on or not

alright it's a crappy pic but it's the rubber bushings that goes in between the screw and the servo ears

I never use them. I will either use RCBros Servo Clamps or cone washers when using a larger servo.

[Scattman]

Never

[losikid]

I haven't, but they're supposed to keep the ears from breaking off on a hard impact or something.

they are suposed to but to not i had them on andi broke 2 ears off just get clamps or make ur own or washers

[demonoid369]

Thanks guys, I was thinking the same lines as to taking them off before but wasn't sure, now I'm going to lol

[2500hdon37s]

never used them, and even RTR's dont come with them.

I would assume these were mainly use in airplanes and helicopter, to reduce vibration during its flight. Cranking the screws down would lead to stripping, adding clamps or washers would also lead to extra weight which is a no-no in aircrafts. Just my 2 cents. BTW, I never use those rubber thingy as you decribed.

+1.
I just use small steel flat washers under the screw head to spread the loads.
The rubber grommets are vibration isolators, needed for other servo applications.
In a crawler, there is really no vibration (other than dropping off a rock....) and the rubber adds some "give" which we DON'T want.

There's supposed to be a brass bushing that goes through it after you put it on the servo ears, that way the screw tightens down on the bushing and not the servo ears.



I don't use them since I got some RCBros clamps.

I like to use them in most cases. It helps from breaking servo cases. I think in the last 6-7 years, I've only broke 2 servo cases, maybe three. More than likely, those broke when the "rubber thingy's" weren't being used.

[demonoid369]

Ya I couldn't think of the name till I posted up the pic lol so it was called rubber Thingy, so far my last servo, which was a jr9100, I remember not using the bushings and it was fine, but tue 645 that I got in a deal awhile back did, so when I got my new servo I decided to ask and see what was up with them

[Twiztid Metal]

Well what kind of servo did they come with? most dont come with them, Iv never used them, but If the servo was a cheapy servo and came with them, you may want to atleast use them, because the plastic could break just by tightingin the screws lol


There is a reason.....

What servo's don't come with them? I've never bought a new servo that didn't haven them little "rubber thingy's"

[mjderstine]

i have never bought a servo that didnt come with them, at least 4 different servo horns, screws to attach them, the collars to go through the "rubber thingys".

they are deg designed for aircraft to help keep the high frequency vibes from killing the internals from the engines. but i also them in all my vehicles as well. they really help keep things from breaking.

OK, I'll be the "butthead"........"Sounds like you & your other 1/2 have an issue, tell her it was cold & she doesn't need a 'rubber thingy', just wait until the room warms up..........."
