Default 2.0 Servo question

Does everyone use the rubber gromets that come with their servos on the 2.0 buggy? I am running hitec servos and when i looked at the servo sheet for setting up the servos, losi did not use the gromets. The screws also are not long enough when i use the gromets etc. I have always used them and that is why it threw me off. Could someone confirm that its ok to run it like this?

I have had throttle servo issues with the 2.0 and a fellow racer, who also happens to race for team losi told me to always use the rubber garments I just get longer screws. Since I started using the rubber garments no more servo failure.

ALWAYS USE THE GROMMETS!

I'm new to cars but not to servos that are exposed to major vibrations (nitro planes.)

Servos WILL be damaged by direct contact vibration and the grommets greatly reduce this effect.

Is this on both steering and throttle? And can anyone else comment on this as well?

Yeah its just weird they show the car without them in the setup sheet and account for the spacers without them.

Your going to get the same vibration on both servos.

The only time grommets arent absolutely needed is with electric planes because of the lack of vibration.

If someone here posts that they don't use rubber grommets on a nitro car and never had an issue I will be greatly surprised.

Is it the grommets that are too thick or the brass inserts that came with the servos?

If you have the RTR maybe the stock grommets and inserts will work on the new servos?

Or is it because you are needing to use the spacers?

dont get me wrong just to be on the safe side i DO use the rubber grommets now, but i owned both the losi 1.0 buggy (for about 8 months) and the losi 2.0 buggy (for about 6 months) and NEVER once used the grommets on either the throttle or steering servo and i never lost a single servo. i was and still am running a JR 9100t for steering and a 8800s for throttle. till this day still no issues. but i do use them now on my mugen mbx6 just as a precaution

They were installed on the 8ight RTR when I bought it so I used them when I installed the Hitec servos. The Losi hardware is to large to fit through the Hitec brass insert so I used the Losi inserts with the Hitec grommets.

That being said, this is the only vehicle I've EVER used the grommets on in 20 years and at least as many cars including 4 nitro powered vehicles. I have never had a servo fail for any reason, ever. I ordered new hardware for the 8ight this week and will be removing the grommets.

Check it out rubber garments installed and they tell me these servos are invincible.

I will 2nd that....Vibrational harmonics are KILLER's on servo's....the Pot's and solder joints do not like being rattled around so much.....

madweazl 20 year's ago....we didn't have the technology we do today and the motor's were Nothing like that are now a days.....more then double the power which will equate to more vibration...its just the way thing's are.

Frank L you never used to run the Grommts did you ?

i know there were a couple stubborn guys who have said it to me over the years...but cant remember if you were one of them or not.

My last gas car wasnt 20 years ago and when it comes to vibration I'm willing to be they're smoother now than they ever have been. I'm not doubting there can be adverse effects but I've never had one.
